Drill bit STANLEY STA52001 – 3 mm diameter, 70 mm length, 1 pc

STANLEY STA52001 drill bit, single piece with a 3 mm cutting diameter and 70 mm overall length, is intended for precision drilling with compatible portable and bench drills. The bit is suitable for small-diameter holes in wood, plastics and light metals where a standard twist drill is required. This single unit provides a spare or replacement bit for occasional and professional use and fits common three-jaw chucks and keyed chucks of standard drills.

Advantages

The 3 mm diameter and 70 mm length provide a balance between reach and rigidity for accurate hole placement. Made to STANLEY quality standards, the bit offers consistent geometry for straight drilling and predictable chip evacuation in appropriate materials. Supplied as a single piece, it is convenient for replacing a worn or broken bit without buying a multi-pack.

Suitable for

• Drilling small-diameter holes in wood
• Precision drilling in plastics
• Light metal drilling where a small twist bit is adequate
• Replacement or spare bit for portable and bench drills

Key specifications

• Cutting diameter: 3 mm
• Overall length: 70 mm
• Applicable materials: wood, plastics, light metals
• Quantity: 1 piece
• Compatible with standard drill chucks (three-jaw and keyed chucks)

How to use

Select a drill with a chuck that accepts the bit shank, securely clamp the bit in the chuck, and set the drill speed appropriate for the material (lower speeds for metals, medium to higher speeds for wood and plastics). Mark the drilling point, use a centre punch or pilot mark if precision is required, and apply steady pressure while keeping the drill perpendicular to the workpiece. Withdraw the bit periodically on deep holes to clear chips and reduce heat buildup.

Usage recommendations

For best results, use cutting lubricant when drilling light metals, control speed to avoid melting plastics, and support workpieces to reduce vibration. Replace the bit when cutting edges become dull to maintain hole accuracy and reduce the risk of workpiece damage.
