8.3mm Countersink 75° HSS 3-Flute Cylindrical Shank, Right-Hand - TECWERK

The combination of HSS construction and a 75° cutting angle ensures consistent, burr‑free seating while the three cutting edges provide smooth material removal; order the TECWERK conical countersink directly from Metav Werkzeuge or request specialist advice if required.

Conical countersink 75° Ø8.3 mm – TECWERK (HSS, 3 flutes, 6 mm shank)

The Conical countersink 75° Ø8.3 mm – TECWERK is a high‑speed steel countersink designed for burr‑free countersinking, deburring and seating in steel, cast and non‑ferrous metals.

• HSS Form C with three flutes
• 75° angle for precise seating
• Suitable for steel, cast and non‑ferrous metals

Precise seating and a clean finish for reliable assemblies

Made from HSS and shaped to a 75° cone, this countersink gives a consistently true seat for countersunk fasteners and rivets, reducing rework and assembly alignment issues. The Ø8.3 mm cutting diameter and three cutting edges produce a fine surface profile that minimises burrs and prevents chatter; the result is repeatable quality in both prototype and production runs. Less need for secondary finishing saves cycle time and improves joint reliability.

Durable design for varied workshop materials

The tool’s Form C geometry and right‑hand cutting action are matched to common workshop demands, providing long tool life across a range of substrates. Compatibility with steel, cast iron and non‑ferrous metals makes the cutter a versatile choice for mixed‑material workbenches. The 6 mm shank and cylindrical mounting ensure secure clamping and straightforward tool changes, supporting continuity in batch processing and repair tasks.

Predictable machining parameters for efficient processes

Optimised for careful material removal rather than high‑speed stock removal, the countersink delivers its best results at low cutting speed with a recommended feed of 0.09 mm/rev when machining steel up to the specified force range. Following these parameters helps to avoid excessive heat and premature wear while maintaining the desired burr‑free finish. The performance profile supports stable cycle times and reduced scrap rates in serial operations.

Easy integration and practical workshop advantages

With a compact design and standard shank dimensions, the cutter integrates seamlessly into existing drill holders and collets that accept a 6 mm shaft, simplifying adoption into established tooling sets. Its burr‑ and chatter‑reducing action translates into less manual deburring and faster downstream assembly.

FAQ

What materials can be machined with this countersink?
The TECWERK conical countersink is suitable for steel, cast iron and a range of non‑ferrous and light metals, providing burr‑reduced edges across these substrates.

What is the recommended feed for countersinking in steel?
A feed of 0.09 mm/rev is specified for steel up to the indicated force range to achieve a clean finish and minimise tool wear.

Which shank size is required for mounting?
The cutter features a 6 mm cylindrical shank and is intended for holders or collets that accept a 6 mm shaft.

How does the tool reduce burrs and chatter?
The combination of three cutting edges, Form C geometry and a 75° cone ensures smooth cutting engagement and reduced vibration, resulting in burr‑free seats.

Is the countersink suitable for production use?
Yes; the HSS construction and the optimised cutting geometry make the countersink appropriate for both repair work and small to medium production runs where consistent finish and tool life are required.
