Countersink drill bit STANLEY STA61500 — diameter 1 cm, 1 piece, blister pack

STANLEY STA61500 countersink drill bit with a 1 cm diameter is a single-piece tool supplied in blister packaging, designed to create conical recesses for screw heads and to chamfer holes in wood, soft metals and plastics. The bit has a hex shank for secure fit in hand drills and drill drivers and is intended for repair, assembly and finishing tasks where a 1 cm countersink is required.

Advantages

The countersink bit provides a clean, consistent conical recess that improves screw seating and reduces splitting in wood. The hex shank ensures a stable connection to the drill chuck, reducing slippage during operation. Supplied as a single unit in blister packaging, it is convenient to store and transport and suitable for both occasional DIY use and professional maintenance jobs. The black finish helps to resist wear and provides visual contrast against lighter materials.

Suitable for

• Countersinking screw heads in wooden boards and panels
• Chamfering drilled holes to prevent splintering in wood
• Preparing holes in soft metals and plastics for flush fasteners
• Use with hand drills and drill drivers for on-site repair and assembly

How to use

Install the countersink bit into the chuck of a hand drill or a drill driver, ensuring the hex shank is seated firmly to prevent rotation or slippage. Mark the screw position and drill a pilot hole if required. Use controlled speed and moderate pressure to create the conical recess; reduce speed for metals and plastics to avoid overheating. Periodically withdraw the bit to clear chips and inspect the countersink depth until the screw head will sit flush or at the desired depth.

Usage recommendations

For best results, select a pilot drill size appropriate to the screw core diameter and adjust drill speed to match the material: higher speeds for softer woods, lower speeds for metals and plastics. Wear eye protection and secure the workpiece to prevent movement. Inspect the bit for wear before use and replace when the cutting edges become dull to maintain clean countersinks.
