TECWERK 120° Countersink, 12.4 mm HSS, 3-flute, 8 mm shank

The TECWERK 120° countersink is a high-speed steel cutting tool for burr-free countersinking, deburring and chamfering in steel, cast iron and non‑ferrous metals.

• HSS, Form C, 3 cutting edges
• 120° countersink angle
• 8 mm cylindrical shank
• Best results at low cutting speed

Consistent, burr‑free countersinking for production use

The combination of high-speed steel (HSS) and a three‑flute geometry produces smooth cutting action with reduced vibration, which leads to burr‑free edges and less rework. The three cutting edges distribute cutting forces evenly, lowering radial load and improving surface finish when creating conical seats or chamfers. As a production tool, this design supports repeatable results across series work and maintenance tasks, improving process reliability and reducing scrap rates.

Clear material compatibility and machining parameters

Designed for use in steel, cast iron and non‑ferrous metals, the tool gives predictable performance when run at conservative spindle speeds. The manufacturer data specifies a recommended feed in steel up to 500 N: 0.14 mm/rev, a practical guideline that balances cutting forces and tool life. The 120° angle suits countersinking for flat‑head fasteners and provides a broad contact surface that eases alignment. Explaining the numbers: the feed figure indicates the linear advance per revolution and helps set stable machining conditions for consistent surface quality.

Robust shank and cutting direction for workshop compatibility

The 8 mm cylindrical shank fits standard chucks and collets, simplifying tool changes and integration into common drilling stations or light milling setups. The tool is right‑hand cutting, optimised for standard clockwise spindle rotation. The cylindrical shank combined with the HSS body gives a compact, rigid tool that resists chatter when used within the recommended cutting parameters, supporting quieter operation and stable feeds in everyday workshop use.

Practical applications and productivity benefits

Ideal for deburring, countersinking and chamfering tasks, this cutter reduces secondary finishing work and speeds up cycle times in both repair and production environments. The Form C geometry and low‑speed preference make it particularly suitable for delicate surfaces and softer non‑ferrous components where excessive heat or aggressive cutting would deform edges. In short, the tool helps maintain component integrity while streamlining assembly preparation and finishing operations.

FAQ

What materials is this countersink suitable for?
The TECWERK 120° countersink is specified for steel, cast iron and non‑ferrous metals, making it versatile across common workshop materials.

How should the spindle be set for optimal results?
Optimal results for the TECWERK cutter are achieved at lower cutting speeds, with the recommended feed in steel up to 500 N set at 0.14 mm/rev.

Which holders accept the shank of this tool?
The 8 mm cylindrical shank is compatible with standard chucks and 8 mm collets used in drill presses and light milling machines for straightforward mounting of the TECWERK countersink.

Is the tool suited to series production as well as maintenance work?
Yes, the three‑flute HSS design provides repeatable, burr‑free edges that benefit both series production and repair tasks where consistent finish is required.

What does 'Form C' indicate for this countersink?
Form C refers to the cutter geometry that balances cutting stability and surface finish; for this countersink it supports smooth chip evacuation and a uniform chamfer profile.
