How to use
Secure the drill bit in the drill chuck and tighten firmly. Mark the drilling point and, if necessary, use a centre punch to prevent slippage. Start drilling at low speed to establish the hole, then increase speed as appropriate for the material. Use steady, moderate pressure and withdraw occasionally to clear chips. For metal and thin sheets, use cutting fluid or lubricant to extend tool life and improve finish when applicable.
Usage recommendations
Use appropriate personal protective equipment such as safety glasses and gloves. Match drill speed and lubrication to the metal being worked to reduce wear and prevent overheating. Replace the bit if signs of excessive wear or chipping appear to maintain hole quality and operator safety.
