Choose the Correct Fit
Confirm that the required finished diameter is among the #7 bit’s marked sizes.
Match the drill setting and lubrication to the work material. Clamp thin stock so it cannot spin.
Installation & Care
Seat the shank securely in the drill chuck. Start square and stop advancing once the chosen step reaches the required depth.
Allow the cutter to cool before handling it. Clear chips safely and inspect the cutting edges before the next hole.
