DIN 1897 Short Shank HSS Twist Drill Bit Metal Drilling Bit
1. Qualified HSS(M35/M2/4341/4241) raw materials ensure sharp and fast execution in any material for clean results
2. Premium Heat treated black oxide is durable and withstand heavy duty operation for a long tool life
3. Black Oxide Surface Treatment holds up lubricant better for smoother drilling
Features
1. Grinding technology: Use powerful grinding wheel to make the blade groove more sharp and smooth,making the drill bit more durable.
2. Spiral groove:S - type spiral groove helps to remove chips easier and work more efficient.
3. 118° and 135° split points:118 drill bits are more suitable for soft materials cutting,like mild steel or cast iron.135 drill bits are suitable for hard steel,especially for hole diameter 4times as the drill bits’ diameter.The thick chips produced when cut hard materials reduce the working hardening of the cavity.
