This 3.5 mm drill bit is intended for standard drilling tasks in wood, plastics and thin metals depending on the drill used and the workpiece material. Supplied as one piece, it serves as a maintenance and repair item for workshop and household use.

Advantages

The drill bit features a precise 3.5 mm diameter and a 70 mm overall length that provide reach and accuracy for small- to medium-depth holes. Its geometry and material are suitable for general-purpose drilling when matched with the correct drill speed and clamping.

How to use

Fit the STANLEY 3.5 mm drill bit into the drill chuck and tighten securely before operation. Select a drilling speed appropriate to the material: lower speeds for metal, medium to higher speeds for wood and plastics. Use steady, even pressure and allow the bit to cut without forcing. For metal drilling, apply cutting fluid or intermittent drilling to reduce heat and extend bit life. After use, clean debris from flutes and store the bit in a dry place to avoid corrosion.

Usage recommendations

Check drill chuck compatibility and run a test hole in scrap material to confirm speed and feed. For precision holes, use a pilot or guide and clamp the workpiece securely. Replace the bit when wear or chipping is visible to maintain hole quality and safety.
