100% High quality and Brand new. The gears is made from YG8 tungsten carbide steel and the rigidity varies from The hole saw has a twist drill bit inside, which is undetachable. 64HRC to 65HRC. Sharp gears and anti-cutting with lower consumption make the product a long service life. Carbide teeth for fast cutting of clean, round holes. Suitable for hand held electric drill, stand motor-driven drilling machine and mobile ribbon type magnetism drilling machine. Cuts quick, precise holes in stainless steel, mild steel, iron, copper and brass. Can drill about 20mm depth Please noted that if you cut the hard material such as steel, ceramic tile...you need to use the oil or water to low the temperature, if not, maybe the drill bit will be broken due to high temperature, please understand Application: drill machine, do not advocate the use of drill machine. Use the matters needing attention: The knife cut materials must be fixed, not mobile, and opening into a 90 degree angle. When the positioning drill through, please wait for a moment, and then slowly drilling. In the process of operation, such as abnormal or cutting is not ideal, please stop working, to cut down on the job. Upper and lower screws do not too hard, so as not to turn the screw slide, such as the emergence of the store does not pay any responsibility. Processing thickness more than 15MM, please go to the next spring, please do not drill metal material under 1.5MM. Available in the bench drill, magnetic drill, drill, the use of pneumatic drill, drill.

Not for Impact Use, Bench Drill Machine, Radial Drill Machine, and Magnetic Drill Machine Applications: Aluminum, Copper, Brass, Mild Steel, I Beam, etc. of up to 4 mm (5/32”) thickness in combination with HSS Center Drill RP Plates, Hardened Steel, Stainless Steel, Resin Plates, etc. of up to 4 mm (5/32”) thickness in combination with Carbide Tip Center Drill

Specially developed robust head geometry with optimum 4 x 90° symmetry of carbide tip reduces jamming when hitting reinforcing steel.Centering point with 130 point angle ensures easy spot drilling with pinpoint accuracy and provides optimum guidance during drilling.The robust secondary cutting edge for 16mm diameters and larger, supports the primary cutter for faster drilling.Shorter spiral windings for faster transport of drilling dust from the head to the flute ensures less wear and heat build up at the tip.Wear mark on both sides of primary cutter guarantees diameter accuracy for anchor fittings – life time indicator in warranty cases.Patented reinforced flute geometry ensures lower vibrations for smoother drilling. The stronger flute means less breakages and better transfer of hammer energy to the tip.Deep flute shoulders give high volume dust removal for optimum drilling speed less wear and heat build up. Suitable for drilling general masonry including brick, block, concrete, reinforced concrete and natural stone.PGM marked for guaranteed exact sized drilling holes to ensure anchor specifications are not compromised.

2 cutter SDS plus drill bits suitable for masonry and concrete. The solid carbide tip with centering point and optimised flutes offers fast drilling speeds in a contractors, low cost option.
