Sheet-metal peeling drill 4–20 mm HSS (71 mm, 2 flutes) – TECWERK

The Sheet-metal peeling drill 4–20 mm HSS (71 mm, 2 flutes) is a universal drilling and countersinking bit designed for precise, chip-minimising boreholes and countersinks in thin sheet materials and plastics.

• Shaft with 3 clamping flats
• Conical cutting edges for shearing cut
• Countersink angle 20° for clean countersinks
• HSS, for sheet metal and plastics

Precision and productivity for sheet-metal operations

The drill is engineered to produce a shearing cut that reduces burr formation and rework. With its HSS cutting material and radially relieved, conically increasing cutting edges, the bit slices through thin metals rather than tearing them, which results in smoother hole edges and faster post-process handling. The combination of two flutes and a fine 20° countersink angle supports a controlled chip flow and consistent countersink geometry, so fewer secondary operations are required and production throughput improves.

Secure clamping and machine compatibility

A 8 mm shank with three clamping flats ensures firm retention in standard chucks and quick-change holders, reducing runout and wobble in repetitive tasks. The design is intended for use on any conventional drilling machine, allowing integration into existing workflows without specialised adaptors. The reliable shank interface and two cutting edges translate into predictable tool life and reduced downtime for bit changes, which is particularly valuable in batch production.

Versatility across materials and applications

Although optimised for sheet metal, the geometry also performs well in a range of non-ferrous and polymer materials, including certain plastics, making it a practical single-tool solution for mixed workshops. The universal nature of the bit reduces the number of tool changes on the shop floor and lowers inventory complexity while preserving the quality of drilled holes and countersinks across different substrates.

Practical advantages and maintenance

Maintenance is straightforward: the hardened HSS body tolerates regrinding for a number of resharpening cycles, and the conically stepped cutting edges maintain their beneficial shearing action after reconditioning. For operations seeking a balance of clean hole quality, simple handling and cost-effective tool life, this bit provides a pragmatic, performance-driven option that reduces downstream finishing and inspection effort.

FAQ

What materials is this drill suitable for?
The TECWERK sheet-metal peeling drill is optimised for sheet metal and is also suitable for a variety of plastics, offering a clean shearing cut in thin materials.

How does the shearing geometry improve hole quality?
The conical, radially relieved cutting edges produce a shearing cut, which reduces burrs and yields smoother hole edges compared with conventional twist drills.

What clamping system is required for the shank?
The bit features an 8 mm shank with three clamping flats, ensuring secure retention in standard chucks and quick-change holders.

Can the drill be used on any drilling machine?
Yes, the design permits use on conventional drilling machines, making it adaptable to most workshop setups.

Is the material resharpenable?
Made from HSS, the bit can be resharpened to extend service life while preserving its shearing performance.
