How to use

Apply cutting fluid or lubricant when required to reduce heat and extend tool life. For deep holes, periodically retract the bit to clear chips and prevent clogging. Maintain a stable drill setup to avoid deflection and ensure a precise cylindrical hole.
Usage recommendations
Use appropriate personal protective equipment, clamp the workpiece securely, and follow the drill manufacturer’s guidance for speed and coolant. Match drill speed and lubrication to the specific metal to optimize performance and tool life.
