71mm Sheet Countersink Drill HSS-Co Two-Flute Universal For Sheet And Plastics, 8mm Shank - TECWERK

Take advantage of the combination of HSS‑Co cutting material, a secure 8 mm shank with three flats, and a radially relieved, conically rising geometry that produces a clean, peeling cut in sheet materials; order directly via Metav Werkzeuge or consult our specialists for application advice.

TECWERK sheet-metal peeling drill 4–20 mm, HSS‑Co, 71 mm overall length

The TECWERK sheet-metal peeling drill is a universal two‑flute twist drill engineered for burr‑reduced holes in sheet metal and plastics, suitable for standard drill rigs.

• HSS‑Co cutting material for extended life
• 8 mm shank with three flats for secure clamping
• 20° countersink angle for burr‑free hole edges

Achieve clean, burr‑reduced holes for faster assembly

The tool’s defining feature is its radially relieved, conically rising cutting edges, which create a controlled peeling cut rather than a conventional chipping action; this reduces burr formation and minimises the need for secondary deburring operations. The result is a measurable improvement in throughput and consistent hole quality in thin materials. The HSS‑Co grade provides wear resistance under elevated cutting temperatures, so cycle times remain stable even in production environments.

Secure clamping and repeatable concentricity

A smooth production flow depends on tool stability. The 8 mm shank with three flats ensures reliable torque transmission and prevents slippage in standard three‑jaw chucks and quick‑change holders. With two cutting edges and a balanced geometry, runout is reduced and hole position repeatability improves, which supports automated workflows and reduces rejected parts. These mechanical advantages translate directly into less downtime and fewer quality checks per batch.

Versatility across materials and machines

Designed as a universal tool, the drill performs well on a variety of thin materials: primarily sheet metal, but also many plastics. The 20° countersink geometry forms clean edges that are beneficial for rivet or fastener seating and for components that will be painted or surface‑treated. Compatibility with conventional drill machines makes integration into existing shops straightforward, avoiding costly fixture changes.

Practical specification that supports shop planning

With an overall length of 71 mm and a drilling range from 4 mm to 20 mm, the drill is sized for general workshop and light‑industrial applications. The combination of HSS‑Co cutting material and the peeling geometry supports longer tool life and fewer tool changes, which simplifies inventory decisions and reduces indirect labour costs. Where predictable, repeatable hole quality is required, this tool contributes to leaner production processes.

FAQ

What materials is this drill suitable for?
The TECWERK sheet‑metal peeling drill is intended mainly for sheet metal and is also suitable for many plastics due to its peeling geometry and HSS‑Co cutting material.

How does the peeling cut improve hole quality?
By producing a peeling action rather than conventional chipping, the tool reduces burr formation and creates cleaner edges, which lowers the need for secondary deburring on the TECWERK drill.

What clamping is required for reliable operation?
Secure clamping in a chuck or holder that accommodates an 8 mm shank with three flats is recommended to prevent slippage and ensure concentricity when using this TECWERK tool.
