Drill Bit set STANLEY STA51023 universal cylindrical 3 mm, 2 pcs

STANLEY STA51023 is a set of two universal cylindrical drill bits with a 3 mm diameter intended for general-purpose drilling. Manufactured for everyday workshop and domestic use, these small-diameter bits are suitable for creating precise 3 mm holes in a variety of materials. The twin pack provides a spare for continued work without interruption and supports common DIY, maintenance and light trade tasks.

Advantages

These 3 mm cylindrical drill bits offer a compact solution for accurate holemaking in wood, plastics and thin metal sheets. The universal design balances cutting performance with endurance for routine drilling. Supplied as a pair, the set reduces downtime by providing a replacement bit when one dulls or breaks. The bits are sized for compatibility with standard chucks and handheld drills used in workshops and for home improvement.

Suitable for (tasks / use cases)

• Drilling precise 3 mm guide or pilot holes in wood and composite panels
• Working with plastics and acrylics for fittings, fasteners or cable routing
• Light metal drilling on thin sheet, brackets and enclosures
• General DIY repairs, mounting small fixtures and assembling furniture
• Workshop prototyping and small-scale fabrication where small holes are required

Key specifications

• Compatibility: standard drill chucks and handheld drills

How to use

Select the appropriate drill speed and clamp the workpiece securely before drilling. Install the 3 mm cylindrical bit in the drill chuck, ensuring it is centered and tightened. For wood and plastics, use moderate speed and steady pressure; for light metals, reduce speed and apply consistent, gentle feed to avoid bit overheating. Consider using a backing piece to prevent blowout when drilling through thin panels. Replace the bit from the pair when cutting performance decreases.

Usage recommendations

Wear appropriate eye protection and follow safe drilling practices. For longer bit life in metal, use cutting lubricant and moderate speeds. Store the spare bit in a dry place to prevent corrosion and inspect before use for any signs of wear or damage.
