How to use

Secure the Proline 92840 drill bit in a compatible drill chuck, ensuring the straight shank is clamped firmly and concentrically. Select an appropriate rotational speed and feed rate for the metal being drilled, and use cutting fluid or coolant as required to reduce heat and extend tool life. Apply steady pressure and allow the bit to cut at its own pace to avoid bending or breakage when drilling deep holes. Periodically clear swarf from the hole to maintain efficient cutting.

Usage recommendations

For best results, use appropriate coolant and moderate speeds for the specific metal being drilled. Inspect the chuck fit and bit condition before each use, and replace the bit if wear or damage is visible to maintain accurate, centered drilling.
