Single STANLEY drill bit STA50092 with a 4 mm cutting diameter and 75 mm overall length supplied in a blister pack. This one-piece drill bit is intended for standard drilling tasks in wood, plastics and light metals when used with compatible drills. The cylindrical shank fits common chucks and provides stable rotation for creating precise 4 mm holes in repair, installation and DIY projects.

Advantages

The drill bit offers a consistent 4 mm hole size and a 75 mm length that reaches through thin panels or into assemblies. The cylindrical shank ensures compatibility with keyless and keyed drill chucks. Supplied in a blister pack, the single-piece packaging protects the cutting tip during storage and transport and makes it easy to identify and handle the bit on the job site.

How to use

Install the 4 mm drill bit into the drill chuck and tighten securely. Select a drill speed appropriate for the material: lower speeds for metals, moderate speeds for plastics, and higher speeds for wood. Mark the drilling point and, if needed, use a center punch or pilot mark to prevent wandering. Apply steady, even pressure and allow the drill bit to do the cutting; withdraw occasionally to clear chips when drilling deeper holes. After use, store the bit in its blister to protect the tip.

Usage recommendations

Use the drill bit with a compatible drill rated for the intended material and wear appropriate eye and hand protection. For metal work, clamp the workpiece securely and apply cutting fluid for cleaner holes and longer bit life. Avoid excessive side pressure and overheating to maintain dimensional accuracy of the 4 mm hole.
