Product description
- PACKING LIST 1 pack of drill bits in 4.0mm cutting diameter, 25mm 0.98 inch flute length, 50mm 1.97 inch overall length, 130 Point Angle
- FEATURE Cemented Carbide twist drills have become the preferred tool for industrial drilling due to their exceptional performance. With ultra-high hardness, they can effortlessly machine difficult-to-cut materials like hardened steel and stainless steel. Their wear resistance is 5-10 times that of HSS drills, significantly extending service life. The excellent thermal stability supports cutting speeds 2-3 times faster than conventional drills
- APPLICATION Carbide twist drills with titanium aluminum silicon nitride coating are suitable for machining high-hardness materials due to their ultra-high hardness and heat resistance, including hardened steel, alloy steel, stainless steel, titanium alloys, cast iron, hard plastics, and wood.
- 130 POINT ANGLE A characteristic feature of carbide drills, which provides enhanced cutting stability and self-centering capability through increased contact area between the drill point and the workpiece.
- INSTRUCTION The twist drill should be at a 90 angle to the workpiece. When drilling different materials, the drilling speed needs to be adjusted. The harder the material, the lower the drilling speed should be. Adjusting the speed can improve cutting efficiency, extend tool life, and reduce material damage.
