Drill for a perforator - what is it?
In the advantages and advantages of guns for the device openings and holes in concrete or brick walls and partitions are convinced by all who at least once performed such work. Indeed, the puncher is indispensable in such cases, especially if you need to drill or chisel, and combine percussion drilling.
Unlike drills, perforators are armed with special locks-cartridges, into which are installed interchangeable working attachments in the form of various chisel-like tips, drills and blades. Since the formation of various holes in very hard materials is the main task of a perforator and a drill, the change of such a workpiece should be done quickly, in one or two movements.
The SDS standard just so allows you to fasten any nozzle, for example, a drill bit for concrete for a perforator. It is enough to insert the shank into the holder and turn it. Everything, the attachment is fixed, you can work. But here's how to choose such a nozzle, we'll look at it just below.
A set of drills for a perforator - what determines the type of drill?
Depending on the class, the perforators can be light, medium and heavy( real hammers).Accordingly, the class is designed and replaceable working attachments. So, the already mentioned type of liner plus usually has a set of drills for a perforator of middle class.
Well, for heavy punchers, accordingly, there are a number of replaceable working attachments with liners of the max type. Specialists do not recommend to install on the perforators of the middle class sets of nozzles, designed for heavy punchers, during the work. Although manufacturers, trying to cater to the needs of the consumer, produce a large number of all kinds of adapters, which allow installing borax "maksi" in perforators "pluses".
But often their dimensions are not comparable, the drills for a heavy puncher weigh sometimes heavier than the middle class tool itself. Therefore, it makes no sense to rape a puncher, not designed not only to perform such heavy work, but also to install max-drills.
Drill for concrete for a perforator - features of the choice and use of
There are many designs of Boers, but basically it resembles a drill, with a spiral cutting part. Like a drill, the spiral automatically removes slurry and broken pieces of material from the working area. The very cutting edge of the working part is made of carbide materials, has a rounded shape, which increases its strength under impact loads.
Since the working conditions of the replaceable working attachments of the rotary hammers are quite heavy, the most running dimensions are usually offered in sets. For example, a drill bit for a 6 mm perforator, the most common for the installation of a guide profile of a suspended ceiling from GKL or the attachment of a frame structure for a similar wall covering, is sold in ten pieces. This is how it should be purchased, undertaking repairs or construction work.
Drills do not wash and do not cool with water, do not grind, do not level and do not repair. This is an expendable material.
Choosing between the spiral forms of the Boers, it must be taken into account that the steeper the spiral, the better the removal of the waste material, the faster and deeper the resulting drilling. Greater strength in this case will have a variant with a shallow spiral. At shallow apertures, it is preferable to apply it. The manufacturer also depends on the longevity of this consumable. For professional work, you need to choose a quality drill, although the price may be much higher than for "one-time" baits.
In addition, a quality drill from a well-known manufacturer will fit the holder in the shape and size of the shank. While a cheap sample of unknown origin may well not be sustained the dimensions of the grooves and grooves, which will negatively affect the work of the holder cartridge. Therefore, compliance must be sustained, because the damaged cartridge, in turn, will lead to breakage of the drill.
In the course of the work, before each installation of the drill bit into the holder holder, lubricate its liner with a thin layer of oil like lithol. The amount of lubricant is not more than a pea. When working, especially with a long drill, do not move relative to the drilling axis in order not to break the nozzle.
Do not use attachments not intended for this type of work. For example, drilling a reinforced concrete structure with a drill that is not designed for "meeting" with the reinforcement. To avoid overheating, the extraction of nozzles from the holes is carried out once every ten seconds, and the speed of rotation must correspond to the passport speed.
