How to use

Secure the Dremel 640 in the rotary tool collet with the 3.2 mm shank fully inserted and tightened. Select a moderate speed appropriate to the material (lower speeds for plastics and soft metals, medium to high for wood). Guide the bit along the desired path with steady, controlled motion; avoid excessive pressure—let the bit cut at its own pace. Make multiple shallow passes for deeper grooves to maintain accuracy and reduce chipping.

Recommendations

Use appropriate personal protective equipment (eye and respiratory protection) and secure the workpiece. Test on a scrap piece to set speed and feed. For best results on lettering, use slow, steady feed and consider finishing passes to clean edges.
