How to use
Install the Dremel 7144 bit into a compatible rotary tool collet sized for a 3.2 mm shank, tighten securely and set the tool speed according to the material: use lower speeds for delicate materials and higher speeds (up to 25,000 RPM) for harder substances. Apply light, steady pressure and keep the bit moving to avoid excessive heat or gouging. Use appropriate clamps and personal protective equipment (safety glasses, dust mask) when cutting or grinding.
Usage recommendations
For best results, test the bit on a scrap piece of the same material to determine optimal speed and pressure. Replace the bit if diamond coating becomes worn to maintain cutting efficiency and avoid damaging the workpiece.
