Drill Bit Set STANLEY STA51013 universal cylindrical 2 mm, 2 pcs

STANLEY STA51013 is a set of two universal cylindrical drill bits with a 2 mm diameter. These compact drill bits are intended for general drilling tasks and deliver precise small-diameter holes in a range of common materials when material-specific compatibility is observed. The bits are made to fit standard drill chucks and portable drills, making them suitable for workshop, home repair and light professional use.

Advantages

The cylindrical shank ensures secure clamping in standard chucks and reduces wobble during drilling. A small 2 mm diameter provides high precision for pilot holes, electronics enclosures, model making and fine woodworking. The universal geometry is optimized for starting and through holes in metal, wood, plastic and composite materials where a universal bit is appropriate. Supplied as a pair, the set offers a spare or backup bit to reduce downtime during repetitive tasks.

Suitable for

• Drilling pilot holes for screws and fasteners
• Small-diameter holes in metal sheets and light alloys
• Precise holes in wood, plywood and laminates
• Drilling plastic parts, housings and model components
• Electronics and hobby work requiring fine drilling

Key specifications

• Set quantity: 2 drill bits
• Shank type: cylindrical (straight) shank for standard chucks
• Diameter: 2 mm
• Intended use: universal/general-purpose drilling
• Compatibility: designed for use with portable drills and bench drills that accept cylindrical shanks

How to use

Select the correct drill speed and feed for the material you are working with: lower speeds for metals and higher speeds for wood and plastics. Secure the workpiece with clamps or a vise to prevent movement. Insert the 2 mm cylindrical shank into the drill chuck and tighten firmly. Start drilling with moderate pressure, keeping the drill perpendicular to the surface to maintain hole accuracy. Withdraw the bit periodically when drilling deeper holes to clear chips and reduce heat buildup. Replace the bit with the spare from the set when wear or damage affects performance.

Usage recommendations

Use cutting fluid or light lubrication when drilling metals to extend bit life and improve hole quality. For plastics, use reduced speed and steady feed to avoid melting; for wood, a clean, sharp bit and correct speed provide cleaner holes. Inspect the bits for wear before use and replace when edges are dulled or the bit produces oversized or rough holes.
