How to use

Secure the drill bit firmly in the drill chuck and tighten according to the drill manufacturer's instructions.

Start drilling with light pressure to create a pilot indent, then apply steady pressure while maintaining alignment. Withdraw the bit periodically to clear chips and allow cooling when drilling deep holes.

Usage recommendations

For best results, use cutting fluid when drilling harder metals, choose a lower speed for stainless steel and hard alloys, and ensure the drill and bit are properly aligned. Wear appropriate personal protective equipment such as safety glasses and gloves when performing metal drilling tasks.
