How to use

Secure the Dremel 997 bit in the rotary tool collet or chuck compatible with a 3.2 mm shank. Start at a low speed to align the bit and the workpiece, then increase speed up to 25,000 RPM as required by the material and task. Apply light, steady pressure and use smooth, controlled movements to avoid overheating or over-grinding. Cool the workpiece periodically if necessary and replace the bit when worn.

Recommendations

Use appropriate personal protective equipment — safety glasses, gloves and hearing protection. Work in a well-ventilated area and secure small parts in a vise or clamp to prevent slippage. Match the speed and pressure to the material to prolong bit life and achieve consistent results.
