Product Information

Raw Material : Solid Carbide Tungsten Steel

Shank : Extended Shank & Straight Shank

Main Function : Special For Drilling

Edge : Fulrinding of the cutting edge . Double-edge angle 140°

TiPS：The solid carbide twist drill is relatively "brittle" due to its high hardne. Not as tough as high-speed steel. So you can't use                           hand drill to operate. The hand drill shakes a lot, the speed is low, and the drill bit is easy to break.

Before using the tool，please measure the accuracy tolerance of the tool，if the tool accuracy exceeds 0.01mm，please correct it before cutting.

The shorter the tool protrudes from the collect,the better.If the tool protrudes longer,it is neceary to reduce the speed,feed rate or cutting volume。

If producing abnormal vibration or sound during cutting,reducing the speed and cutting amount until the situation improves.

The best way to the steel cooling is spray jet and air jet,which can improve the use of milling .
