Countersink drill bit STANLEY STA61502 — 1.6 cm diameter, 1 pcs

STANLEY STA61502 countersink drill bit with a 1.6 cm diameter is designed to create conical recesses and to deburr holes in wood, metal and plastic when used with compatible drills. Supplied as a single piece in blister packaging, this countersink enables chamfering of screw heads and removal of sharp edges to improve assembly fit and surface finish.

Advantages

The single-piece construction provides rigidity and consistent performance during drilling and countersinking operations. A hex shank ensures secure grip in standard chucks and quick-change adapters. The diameter specified for the cutting head gives a uniform chamfer suitable for common screw sizes, while the black finish helps reduce glare and surface reflections during use.

Suitable for

• Creating conical recesses for countersunk screws in woodwork
• Deburring drilled holes in plastic and sheet materials
• Preparing edges and holes for assembly to improve fit and appearance
• Use with portable drills and drill drivers equipped to accept hex shanks

Key specifications

• Type: countersink drill bit for creating chamfers and deburring
• Cutting diameter: 1.6 cm
• Shank type: hex shank for improved retention in chucks and adapters

How to use

Install the countersink bit into the drill or driver that accepts hex shanks, ensuring the shank is fully seated and secured. Mark the hole centre and drill the pilot hole if required. Run the drill at a moderate speed and apply steady, even pressure while creating the conical recess; withdraw periodically to clear chips. Adjust feed and speed according to the material—lower speeds and light pressure for plastics and thin metals, moderate speeds for wood—to achieve a clean chamfer without burning or tearing the surface.

Usage recommendations

Wear appropriate eye protection and follow standard safety practices when operating power tools. For best results, test the countersink on a scrap piece of the same material to verify the chamfer size and fit for the intended screw, and clear chips frequently to avoid clogging.
