TECWERK sheet-metal peel drill — HSS, 24–40 mm range, 10 mm shank

The TECWERK sheet-metal peel drill is a universal HSS tool designed to produce clean peeled holes and integrated countersinks in thin metals and plastics, suitable for use on standard drilling machines.

• HSS material for long tool life
• 20° countersink angle for precise chamfers
• 10 mm shank with three flats for firm clamping
• Universal tool for sheet metal and plastics

Faster, more consistent holes through peeling action

Built for efficiency, the HSS construction and the tool’s two cutting edges deliver sustained cutting performance while maintaining edge stability. The radially back-ground, tapering cutting edges produce a peeling cut rather than a blunt shearing action; this reduces burr formation and heat build-up, so holes remain dimensionally consistent. For production environments, the result is fewer reworks and a measurable time saving per workpiece.

Clean countersinks and reliable chamfer geometry

The integrated 20° countersink angle ensures a neat chamfer directly during drilling, eliminating the need for a separate countersinking pass. The controlled geometry allows for predictable fastener seating and reduces assembly time. This design detail translates into a practical benefit: a single tool achieves both holemaking and chamfering with consistent outcomes, improving process flow on the shop floor.

Secure gripping and universal machine compatibility

A 10 mm shank with three flats provides positive clamping in chucks and reduces slippage during interrupted cuts. The shaft profile suits standard drill chucks, so the tool is compatible with any drilling machine commonly found in workshops. This universality simplifies tooling logistics while ensuring stable, concentric rotation and repeatable hole quality.

Versatile use across thin metals and plastics

The geometry and material choice make the tool particularly effective for sheet metal processing, while also being suitable for various plastics, widening its application range in repair shops and production lines. The moderate cutting geometry helps avoid melting or deformation when working with softer polymers, and the HSS composition preserves edge integrity when used on steel sheets.

FAQ

What materials can be machined with this tool?
The TECWERK sheet-metal peel drill is suitable for sheet metal and a range of plastics, its geometry minimising burrs and reducing thermal stress on polymer parts.

What clamping system is recommended for best results?
Use a standard chuck that accepts a 10 mm shank; the three flats on the shaft ensure secure clamping and reduced slippage under load.

Does the tool create a countersink at the same time as the hole?
Yes, the integrated 20° countersink angle produces a clean chamfer during drilling, removing the need for a separate countersinking operation.

Is this tool suitable for all drilling machines?
The universal shank design allows the tool to be used on most standard drilling machines; compatibility with specific equipment should be checked for special setups.
