Drills for metal
Drills for metal used for cutting holes in unalloyed and alloyed steel, cast iron, nonferrous metals, etc.This type of drill has a helical shape, hence the appropriate name - twist drills.Twist drills have two longitudinal grooves which remove the chips during drilling.There are several types of tails twist drills - conical, hexagonal and cylindrical.Tapered inserted directly into the machine, cylinder - a
If you are interested in the question: "Which drill for metal is better?" When selecting drill pay attention to the color, it will say a lot about the quality.
Choose quality drill color
If the drill is black, it means that when finishing used superheated steam.This drill has a high wear resistance.
When finishing used for holiday stress relief, the drill will have a faint golden hue.
quality drill for metal have a bright golden hue - to drill a layer of titanium nitride.This is a very high-quality tools have high strength and reduced friction.Mute more expensive than others, but also in quality above the rest.
Average gray drill (the cheapest) has no treatment.The minimum price and the same service life, and nothing more.
See photos of drills for metal, to finally remember kinds of flowers and their inherent characteristics.
marking drills on metal
marking depends on the diameter.Drills are not marked to 2mm, 3mm on drills to indicate the brand, and the diameter of the steel, thicker drill may carry information about the manufacturer and the class accuracy.
Marking drill begins with the letter P - cutting steel.In the form of numerical values also indicate the content of various substances in the alloy.For example K6 - part of cobalt, M3 - molybdenum content.On the import drills marking is in the form of values or HSS Din.
learning characteristics and types of drills, you now know exactly how to choose the drill for metal.We only give examples of high-quality drill bits, which are widely used by professionals.
Twist drills RUKO metal TL 3000 (HSS-G, HSS-E, HSS-G TiN, HSS-G TiAlN)
Drills for metal ruko lineup TL 3000 known to consumers as the high-quality materialat an affordable price.Drill diameter - from 3mm (Phillips are sharpening according to DIN 1412 C).Drills are sharpening angle of 130 °.Depending on the particular model has the coating of titanium nitride, titanium, etc. alyumonitrida
Multipurpose drill, excellent for large drilling depth.It is best suited for materials that form long and medium chips.
drills HSS-G fine drilled carbon and alloy steel, cast iron, copper and aluminum alloy.
HSS-E in addition to carbon and alloy steel drills stainless and acid resistant steel as well as copper and aluminum alloy.
HSS-G TiN and HSS-G TiAlN suited to work with all the above-described materials, and titanium alloy.
Drills for metal BOSCH HSS-CO
drills companies BOSCH lineup HSS-CO are made of high-speed steel by all standards.Drills have an oxide coating that quickly removes chips during drilling.Standard in the form of a chisel edge with an angle of 135 ° with grinding mesh suitable for almost any type of work.
doping of cobalt improves the strength and heat resistance of the drill.The tensile strength of 1000N / mm2, which allows you to handle most types of steel and alloys, as well as to cope with the severe production problems.
accuracy class h8 provides the necessary restraint outer diameter.
Drills for metal titanium-coated HAISSER
One of the most powerful drills that are used under extreme load in household and industrial environments.Drills cruciform sharpening.Titanium coating provides maximum cooling, allowing you to work in the toughest conditions.The main use of the drill is in the sphere of industrial and demanding applications.Angle 135 mesh grinding.Titanium nitride coating provides low friction and a reduction of cold welding.Due to the high wear resistance of drill bits have a unique long life.
Recommended for: Non-alloy and alloy steel, bronze, copper, metal ceramics, Plexiglas, etc.
Drill on metal Zubr "Cobalt»
Drill on metal Zubr made of high speed steel R6M5K5.It has a cylindrical shank.On the strength of the class is classified as A1.Using Co (5%) in the manufacture of the drill bit gives extra strength and resistance to wear.
used drills "Cobalt" drilling non-ferrous metals, stainless steel, hard-tensile steel, etc.Drills are made in accordance with GOST 10902-77.The price of the drill Zubr "Cobalt" is consistent with the quality of the product, so many buyers make a choice in favor of this product.
