Manual centering punch Beta Tools 32AU with 3 mm tip — marking tool for metal, wood, plastic

Beta Tools centering punch 32AU is a manual marking tool designed to produce a clear, repeatable centre mark prior to drilling. The tool features a hardened 3 mm tip that creates a defined impression on metal, wood and plastic, helping to prevent drill bit wander and improving hole placement accuracy. Compact and simple to operate, this centering punch is intended for use across workshop, maintenance and hobby tasks where precise starting points are required.

Advantages

The hardened 3 mm tip provides durable, consistent impressions for repeatable marking. Its manual, one-piece design makes the tool easy to handle and position, while the compact size allows use in confined spaces. Because it requires no power or setup, the punch is immediately ready for marking and offers reliable performance for frequent manual use.

Suitable for

• Marking centre points on metal sheets and plates
• Creating starter dents on wood before drilling
• Preparing plastic parts for accurate hole drilling
• Maintenance and repair tasks requiring precise hole placement
• Hobby and DIY projects with small or detailed components

Key specifications

• Tip material: hardened steel tip for wear resistance
• Tip diameter: 3 mm for precise, small-diameter marks
• Operation: manual hand punch, no power source required
• Construction: compact, single-piece body for easy handling
• Compatible materials: suitable for metal, wood and plastic

How to use

Place the tip of the centering punch at the desired drill centre and hold the tool perpendicular to the work surface. Apply a controlled impact or press the punch to produce a clear dent; for harder materials use a light hammer blow to form a visible impression. Verify the mark location and proceed to drill using the dent as a guide to reduce drill bit wander. Clean and store the tool after use to maintain tip condition.

Usage recommendations

For best results on harder metals, use a light hammer strike rather than excessive force. When marking thin sheets, support the workpiece to avoid deformation. Inspect the tip regularly and replace the tool if the tip shows excessive wear to maintain marking accuracy.
