Cone Drill Metal: recommendations on the selection

The modern market is characterized by the variety of instruments used for any type of work. Cone drill for metal cutting are professional products, which are characterized by long term performance, versatility and ease of use. To select the desired recommended tool to study basic properties of such devices.

Features and characteristics of the conical drill for metal

All conical devices, depending on the work item form, divided into two groups: smooth and graded. Both variants products have a conical shape and are used for processing metal sheets of small thickness. The smooth variation is less convenient because it does not have to perform a precise diameter. When operating with such a drill is necessary to periodically stop and carry out appropriate measurements.

Helpful information! Stepped cone drill through a clear gradation levels, each of which has its diameter, They are more comfortable and are recommended for people who have no experience with similar instruments. Each step in this article is digitally coded, which allows you to quickly determine the correct diameter.

Both types of instruments are equipped with a special groove with sharp edges. It is thanks to the cutting edges occurs drilling a metallic material. The grooves may have different shapes. All conical devices are distinguished by good strength. Most of them can be sharpened, which is a major advantage, allowing to extend the service life of the drill.

It is important to understand that such devices replace multiple tools that are used in normal conditions for the organization of the holes in the metal plates. To work with such products used screwdrivers or drills under the drill. Cone Instruments are suitable for drilling at high speed. However, their use ensures high quality holes edges. In this case, it eliminates the possibility of the occurrence of burrs, which under normal conditions should be removed.

In view of the above characteristics can be said that these instruments have an ideal structure for use with metal sheets. Furthermore, their use allows to process and other materials which makes them truly universal and indispensable. The main objective of such drills - making holes, but they can also be used for other purposes. Quite often tapered products are used for the elimination of defects, obtained by drilling other drilling components.

Cone Drill Metal: advantages and disadvantages

All tools cutting type has positive and negative traits. Before purchasing a product, please conical become more familiar with its advantages. One of the main advantages of such devices is that they can be used to perform holes of various dimensions. One drill of this type replaces a complete set of cutting tools.

These products characterized by high strength properties. This reduces the rate of wear. Another advantage, which also affects the duration of the operation is the speed of such tools. With a taper devices can perform an opening much faster than when using the other cutting elements. This eliminates the possibility of overheating of the drill.

Stepped tools in the shape of Christmas trees, which are also called drill-carrots, have a sharp tip. Such a form allows to significantly simplify the sidebar in a metallic material of any density. As well as such items are used as grinding elements.

Tapered devices provide smooth extension hole diameter in a metal material (and not only). Thus, reducing the likelihood of deformation of the sheet. They can not only be used on hand-held equipment, but also to be installed in stationary machines, which is also a major advantage.

The surface of the conical parts can be equipped with a special protective coating. The modern market offers the buyer a model with a titanium and diamond-coated. The strength of these products, which increases the duration of their use, allows you to spend less sharpening. Sharpen taper step drill, like any other, you can use the grinder. Such tools are a good alternative to the core bit. Large size tapered tools provide the ability to perform large-sized holes.

Note! Such a drill can be used not only in metal sheets for organizing apertures, but in the tubes (round and profiled) and corners.

The versatility of these instruments can not be criticized. However, we should remember that they can not be used for metal products, the wall thickness of greater than 7 mm. Optimum version of the application - drilling holes in thin sheet parts (not more than 4 mm). Drills for metal of this type have the most positive feedback from users.

If special adapters such drills can be installed even in a grinder. The only significant drawback of these devices is their relatively high cost.

Scope of drills for metal cone type

Bevel cutting tools are designed for continuous operation without interruption. This is achieved by strong edges representing the edges of the grooves. Such drills are completely independent. Therefore, for the organization of the holes in this case it is not necessary to use special centering devices.

The scope of application of such tools is quite broad. The shape of the cutting edges, located on the edges of the grooves, can significantly extend the operational tools belonging. These drills can be used for the treatment of not only fine-leaved steel, but other materials, such as:

• cast iron;
• aluminum;
• copper;
• brass;
• plastic;
• drywall;
• wood.

they are also used extensively when working with stainless steel. Drills for metal of this type differ in several working embodiments groove arrangement. The channels can be straight or spiral shape. The second variant is characterized by greater efficiency, but sharpen tool with such a channel is much more difficult.

Nib conical parts facilitates easy entry into the metal material and also has another advantage. Its shape allows you to cope with the vibration exposure occurring during metal drilling. Such benefits are deprived of the usual model of cutting products. As an example, a twist drill for metal cutting 13 mm.

These products are actively used during the installation of sanitary equipment, and they are often used in the repair of automotive vehicles. What other applications of conical parts are there? Among other things, they are in demand in the construction and in the manufacture of electrical boxes.

Especially the shape and dimensions of the conical drill

For a correct choice of the conical cutter must be clearly understood that, what options there are forms of these products on the market. Each type of product has its own advantages and disadvantages. Consider the three main types of such tools:

• conventional (step herringbone);
• truncated without a guide tip;
• combination of the two conical parts.

The latter option consists of two segments, each of which has a different angle of inclination of the surface. The grooves, which include data on the product may also have a different shape.

Helpful information! The maximum diameter of such drills can vary, but most often there are models in which the figure is 32 mm. Cone drill bit for metal 4-32 mm can be purchased in the profile store or order on the Web.

Today, the market can meet and drill a marker pattern, e.g., step product with a maximum diameter of 40 or 50 mm. It is said that the figure in the biggest models does not exceed 60 mm.

When selecting the conical cutter it is also recommended to pay attention to the shape of its tail. This drill is being used to fix the tool in the chuck drill. The following versions of the forms of liners:

• cylindrical;
• triangular;
• Hex.

The last two species are recommended by many masters, as they allow more tightly secure the drill in the working tool. When using triangular and hexagonal cranking instances eliminated, so reducing the risk of injury during drilling metal surface.

Smooth products extend closer to the tail section, which is fixed in the cartridge. They, unlike the step, do not have a clear gradation of diameters. The speed variations of the conical cutting tool height level is 5 mm. However, in some instances the indicator may be different (e.g., 4 or 6 mm). metal drills have a pitch that before stage 12 mm in diameter is 1 mm. More marker levels are characterized by steps of 2 mm.

It is important to remember that define the maximum thickness of the metal material in which the permissible to use a particular bit, can be independently. This option is usually repeats the altitude levels of the conical device.

Recommendations made by the choice of cone drill

Many people who are poorly acquainted with the peculiarities of the various cutting tips, it is difficult to decide on the acquisition of such a tool. In order to avoid mistakes in the selection, you need to learn a few of the highlights.

The first thing to remember is that all nozzles are different in color. This is a very important point, because of the color of the product depends on its specifications. For example, the color of the steel work piece suggests that it is not subjected to additional temperature (or any other) treatment.

Adaptations steel coloring are not characterized by high strength and, accordingly, are more susceptible to wear. They are recommended to be used exclusively for the organization of the holes in the fine-leaved material, as well as for the treatment of plastic, drywall and wood. Cone Drill Metal of this type have the lowest cost.

cutting tool Black says that the product has been further processed by high temperature. Such devices have a higher strength, which increases their operational life.

Note! The tool must be selected on the basis of its operational purposes. Product dimensions may vary, so you should decide in advance as to which holes will be carried out by means of it. Most often, the sale can be found in the cone drill bits for metal 6-36 and 4-32 mm.

Another option, common on the market today - the golden cones. These models have a protective coating, represented by titanium nitride. As a result, they are the technical characteristics far superior to previous analogues.

In embodiments, the step height levels, as already mentioned above, the average is 5 mm. Drills for metal should not have razbezhnosti in this index is greater than 1 mm. This is worth remembering when buying a tool.

What else you need to pay attention? No less importance is the tool brand. Products made little-known Chinese companies, masters do not recommend to buy, because in this case, the chance to purchase low-quality or defective products increases significantly. domestic production Drill have a smaller working life when compared to their foreign counterparts.

Marking tapered cutting tools: what you need to know

Technical characteristics of such products are indicated in cutting a marking which is applied to the outer surface of the tail section. Knowledge of basic notation allows you to choose the quality, and the most suitable for the specific operating conditions of the product. Let us consider in more detail what information is encrypted in the labeling:

• manufacturing material;
• diameter;
• accuracy class.

Labeling Deciphering - a very important step, so you should get acquainted in more detail with possible options. Most products of this type have a 1 mm pitch. Drills for metal, which is inherent in the shape of Christmas trees, differ in many dimensions. This information is contained in the mandatory labeling.

Most often, a letter designation is the beginning of the markup. On most of drills that can be purchased today, stated the Latin letter «P». Such designation tells us that high-speed alloy steel was used for the manufacture of the device. Such a material has high strength characteristics.

Next is the next letter, after which necessarily is worth a certain number. This symbol includes information of metal that has been used as an additive to the alloy steel. The number indicates what percentage of the alloy is in the product.

Note! Labeling is not applied to the product, the diameter of which is less than 2 mm. Drills for metal of this type have too small shank.

After a minor percentage of metal in the mark indicates the maximum and minimum diameters, as well as the accuracy class of devices. It is worth noting that these products often found lettering HSS. Drills for metal of this type are made of high speed steel. After the initial mark marking comprises information about the extension material used in the manufacture of the product.

How to drill holes cone drill: instruction

Operation of the conical cutting element has some features when compared to the process using conventional spiral devices. Thus, to a beginner who does not have experience with such a tool could understand usage patterns, he must study the instructions. Not recommended during operation deviate from the algorithm works, since this can lead to various problems.

To study the technical characteristics of the cutting member can be further acquainted with her drawing. Drills and schemes can be found on the worldwide web without any difficulty. The first stage is a preparatory. At first need to buy and prepare all the necessary tools and materials. Consider what is required in this case:

• conical cutting tool;
• drill;
• preform, wherein the hole is performed.

Selection conical tool depends entirely on what is necessary to make the diameter of the hole in the workpiece. When you select a drill in which the drill bit will be set, it is worth considering that the instrument must have an opportunity to develop the required speed (3 to 5 thousand. rev / min). Before you start, experts advise to fix the drill additional handle. As the blank sheets can be used, made from steel, soft metals, as well as various synthetic materials.

Conventional drills with taper shank to apply for the organization of the holes in the metal much more difficult. Such articles have a simple design, which is not conducive to precise work. After preparing all the necessary tools, you can proceed directly to the drilling of the workpiece. The procedure in this case consists of 4 stages.

First of all it is necessary to fix the cutter holder in the electronic instrument. Next, you need to select and apply an appropriate marking in the place that was chosen for the drill holes.

In the next step the cutting device is applied to the workpiece surface and the drilling is performed. It is important to remember that the product must be placed strictly in a perpendicular position with respect to the workpiece. During drilling, this angle must be followed precisely. Drills for metal that have a conical shape are used for different diameters and are separate tools.

Final stage - gradual implementation in a metallic material with increased speed of revolutions. The end result of this work is a neat hole, the edges of which are deprived of any burrs and other defects.

Note! Many artists say that the usability of such a drill is its main advantage. Therefore, these cutting products are perfect for beginners who do not have the relevant experience.

Popular manufacturers and prices of cone drills for metal

Brand products - a very important indicator, because the cost of goods depends on it, as well as their quality characteristics. Drills, produced popular foreign companies, of course, have a higher price, but it is often justified by the quality and long service life. However, the tools of some domestic brands are not inferior to the American and German counterparts.

The most popular domestic company (for reviews of consumers) - "Bison". Drills for metal of the manufacturer at a fairly good quality cost about 2-3 times cheaper foreign options. Many foreign brands. Consider which ones are prevalent in the market.

Makita. Products of this Japanese brand is recommended by many experts as combine optimal price-quality ratio. Minimum cost of such devices is 1250 rubles. The most expensive devices produced by this company are sold for 14-15 thousand. rub.

Bocsh. Very popular German company engaged in the production of various goods. Tools of this manufacturer are of high quality and have a long service life. Price conical drills of this type is quite high. The cheapest product variants can be bought for 4,000 rubles.

You can also select two other popular brands, namely: Milwaukee, Yato. The first is an American brand. The company is engaged in manufacturing of tapered cutting tools for professional and consumer use. The second company is in Japan. It also manufactures and distributes conical products that exhibit high performance.

The modern market is full of cheap Chinese products that do not have a long application period. Such products very quickly wear out and become useless. Experts do not recommend to buy Chinese goods, despite their attractive cost.

Tapered drills - multifunctional and versatile product, the use of which allows you to work quickly, for which in other circumstances would require a set of common tools. When choosing a tapered cutting tools, it is desirable to immediately determine the budget and focus on the purpose for which the drill will be used.
