How to use
Clamp the straight shank securely in a compatible drill chuck. Select an appropriate speed for the material (lower speeds for harder metals) and use cutting lubricant when drilling metal to reduce heat and extend bit life. Start drilling with light pressure to locate the hole, then apply steady feed until breakthrough. Retract occasionally to clear chips if drilling deep holes.
Usage recommendations
Use cutting oil for improved finish and longer tool life; avoid excessive speeds and pressure to prevent overheating and premature wear. For accurate positioning, consider centre-punching before drilling.
