Factory source Step Drill Bits For Steel - CNC Tungsten Drill Tool Metal Solid Carbide Cutting Bits Spot chamfer drilling bit – MSK
Factory source Step Drill Bits For Steel - CNC Tungsten Drill Tool Metal Solid Carbide Cutting Bits Spot chamfer drilling bit – MSK Detail:
Spotting drill bits or spot drill bits are used to start a traditionally drilled hole. By using the same angled spot drill bits to that of the regular drill bit to be used, an indentation on the exact location of the hole is made. This prevents the drill from walking and avoids unwanted damage in the workpiece. Spotting drill bits are used in metal works such as precision drilling on a CNC machine.
Feature:
1.This item without coating is suitable for copper, aluminum, aluminum alloy, magnesium alloy, zinc alloy and other materials.
This item with Alloy coating is suitable for copper, carbon steel, cast iron, die steel and other materials.
2.Excellent wear resistance and long using life
Produced by Germany machine, high performance for finishing and semi finishing the workpiece (heat treatment) under HRC58 and improve the hardness of cutting tool and using life.
3.Sharp Flute, smooth chip removal
Grinded by high precision machine, big chip removal space. Not break, sharp cutting, smooth chip remove, improve milling processing.
Notice:
1.Fixed-point drilling can only be used for fixed-pointing, dotting, and chamfering, and must not be used for drilling
2.Be sure to test the yaw of the tool before use, please select correction when it exceeds 0.01mm
3.Fixed-point drilling is formed by one-time processing of fixed-point + chamfering. If you want to process a 5mm hole, you generally choose a 6mm fixed-point drill, so that subsequent drilling will not be deflected, and a 0.5mm chamfer can be obtained.
