76mm Sheet Metal Counterbore Drill HSS-Co 2-Flute 20° Countersink, 9mm Shank - TECWERK

Take advantage of the robust HSS‑Co cutting material together with the two cutting edges and the three‑flat shank for reliable, burr‑reduced countersinking in thin materials; order the tool directly via Metav Werkzeuge or consult the advisers for application support.

Sheet Metal Countersinking Drill 16–30.5 mm HSS‑Co, 76 mm – TECWERK

The sheet metal countersinking drill 16–30.5 mm is a two‑flute HSS‑Co tool designed for precise hole enlargement and countersinking in sheet metal and plastics for workshop and light industrial use

• Shank with three clamping flats
• Two cutting edges for smooth chip removal
• HSS‑Co for enhanced wear resistance
• Ideal for sheet metal and plastics

More throughput through a peel‑cut geometry

The TECWERK countersinking tool combines a peel‑cut geometry with a conically increasing cutting edge to reduce cutting forces and improve chip evacuation. The HSS‑Co substrate provides higher red‑hardness and wear resistance compared with standard high‑speed steel, which translates into longer tool life and fewer interruptions. This design lowers the risk of heat build‑up and workpiece distortion, making the tool economically attractive for repetitive tasks in fabrication and maintenance.

Reliable clamping and machine compatibility

A 9 mm shank with three clamping flats ensures secure seating in standard chucks and quick‑change holders, preventing slippage during higher torque operations. The two‑flute layout balances cutting action and stability, offering a controlled feed that reduces chatter on portable drills and drill presses. The total length of 76 mm maintains an effective working reach while remaining compact enough for bench and hand‑held applications.

Clean results on sheet metal and plastics

The tool’s 20° countersink angle and radially ground cutting lips are tuned to produce a shaved, burr‑reduced finish on thin materials. In practice, this means fewer secondary deburring steps after drilling, particularly when working with common sheet metals and softer plastics. The result is improved component appearance and a faster transition from drilling to assembly or finishing operations.

Practical handling and universal application

Marked by a universal application profile, the drill is suited to everyday workshop tasks where versatility matters: from light structural panels to non‑ferrous components made of plastics. The combination of HSS‑Co, two cutting edges and the three‑flat shank supports stable performance in mixed production environments, reducing tool changes and simplifying tooling logistics across jobs.

FAQ

What materials can be processed with this countersinking drill? The countersinking drill is designed primarily for sheet metal and various plastics; the HSS‑Co composition supports common fabrication alloys and softer engineering polymers.

Is the shank compatible with common drill chucks? Yes, the 9 mm shank with three clamping flats provides secure seating in standard chucks and quick‑change holders to avoid slippage under load.

How does the peel‑cut geometry affect finishing? The conically increasing, radially ground edges create a peeling action that reduces burr formation, resulting in cleaner holes and less post‑processing.

Can the tool be used on portable drills? The tool’s two‑flute design and secure three‑flat shank make it suitable for both drill presses and hand‑held machines, provided the machine offers adequate rigidity.

What maintenance is recommended to extend tool life? Periodic inspection for wear and light regrinding when appropriate will maintain performance; the HSS‑Co substrate improves temperature resilience but does not eliminate normal wear.
