Achieve precise 28-degree angled holes consistently with this 10-hole collet block and punch set. Designed for metal, wood, and plastic applications at the bench.

What it does

This robust collet block guarantees repeatable angled drilling without the need for complex jigs. Simply select the appropriate collet for your stock, insert your workpiece, and use the included hardened steel punch to accurately centre it. The block's precisely machined 28-degree angle ensures every hole is drilled at the correct inclination, simplifying batch production of components. Its solid carbon steel construction provides a stable platform for accurate work.

How to use it

  • Select the correct collet size for your material.
  • Position your workpiece and use the punch to centre it.
  • Drill through the collet at the preset 28-degree angle.

Who it's for

Ideal for bench jewellers, silversmiths, and model makers requiring accurate angled holes for findings, settings, or structural elements. This tool replaces the need for manual angle measurement and complex jig setups, streamlining the creation of consistent components for both intermediate and professional makers.

Common questions at the bench

What metal does this punch work on?
Our steel letter, number, and design punches are heat-treated to strike non-ferrous metals: silver (sterling, fine), copper, brass, bronze, aluminium, gold. Striking hardened steel will damage the face. For pewter and very soft alloys, use light strikes.
What size impression do I need?
1–2 mm for ring shanks and small pieces (initials, hallmark-style); 3–4 mm for pendant backs and signed plaques; 5 mm+ for presentation pieces and stamped jewellery components. Bigger is not always better — a clean small mark reads better than a struggle with an oversized one.
What do I strike it with?
A 1–2 lb brass mallet on a polished steel bench block. Do not use a steel hammer — it will deform the punch over time. One firm strike beats two soft ones for a clean impression.
How do I keep the punch sharp?
Polished punches stay sharp for thousands of strikes if you are hitting cleanly on a flat block. If the face starts blurring impressions, polish lightly with 600-grit emery, then a buffing mop on a polishing motor. Replace before the face deforms further.
