PACKING LIST: 2 packs drill bits in 4.1mm (0.16 inch≈5/32 inch) cutting diameter, 35mm/1.38inch flute length, 75mm/2.95inch total length, 135 degree sharp angle
NOTE: High Cobalt HSS typically has a higher number of bores than M2 HSS and M35 HSS under the same conditions, potentially thousands or more. This significantly increases machining efficiency and reduces costs, especially when machining difficult materials.
Instructions: The twist drill should be at a 90° angle to the workpiece. When drilling different materials, the drilling speed must 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.
Function: M42 high speed steel is formulated with a high 8%, high hardness and wear resistance, especially suitable for machining hard materials, excellent heat resistance, suitable for high speed cutting. The titanium nitride (TiN) coating can prevent further oxidation or corrosion of the drill bits and extend the service life.
APPLICATION The M42 material drill bit has a high 8% content, mainly used for demanding professional drilling operations, which makes it suitable for machining medium-hard meters. It is suitable for drilling various materials, including stainless steel, iron, aluminium, copper, plastic and wood.
