8.3mm Countersink 90° 3-Flute HSS-Co Cylindrical Shank - TECWERK

Take advantage of the combination of standardised geometry, a three‑cutting‑edge design and heat‑resistant HSS‑Co for consistent chamfering and reliable deburring results; order the tool directly via Metav Werkzeuge or ask our consultants if needed.

TECWERK Countersink DIN 335 C Ø 8.3 mm, 90° HSS‑Co, 3‑flute

The TECWERK countersink DIN 335 C is a 3‑flute HSS‑Co chamfering tool for clean deburring and spotfacing of drilled holes in steel, castings and non‑ferrous metals

• DIN 335 C standardised 90° geometry
• Three flutes for chatter‑free cutting
• HSS‑Co for stainless and heat‑resistant steels

Consistent chamfers with standardised 90° geometry

Built to DIN 335 C dimensional and cutting geometry, this countersink delivers uniform chamfer profiles and predictable results across production runs. The 90° angle is the industry standard for general countersinking and ensures compatibility with common fastening and seating applications. Consistent geometry reduces measurement rework and supports process stability in workshops and small production environments.

Smoother surfaces and higher productivity from three cutting edges

The three flutes provide an even material removal pattern that produces a rattle‑free cut and a cleaner edge compared with two‑cut designs. This results in fewer burrs and reduced need for secondary finishing. The tool is specified with a recommended feed of 0.09 mm/rev in steel under loads up to 500 N, which balances surface quality and efficient material removal for routine chamfering and deburring tasks.

Cobalt alloy for demanding materials and reliable shank compatibility

Manufactured from HSS‑Co, the tool offers improved hot hardness and wear resistance suitable for machining steel, castings and stainless and heat‑resistant steels where elevated temperatures occur at the cutting edge. The cylindrical shank allows straightforward mounting in conventional holders and drill chucks, making integration into existing workstations simple and reliable while maintaining tool concentricity for repeatable results.

FAQ

What materials can this countersink machine effectively handle?
The TECWERK countersink (DIN 335 C, 90°) is suitable for steel, castings and non‑ferrous metals; the HSS‑Co grade extends capability to stainless and heat‑resistant steels.

What does the specified feed 0.09 mm/rev mean in practice?
A feed of 0.09 mm/rev indicates the axial advance per revolution advised for machining steel under the stated load condition (up to 500 N), balancing surface finish and tool life when using the three‑flute design.

Is the shank compatible with standard holders and chucks?
Yes, the cylindrical shank of the countersink fits conventional drill chucks and toolholders, allowing straightforward mounting in standard workshop equipment.

How does the three‑flute geometry affect finishing and tool life?
The three cutting edges produce a more uniform cut and reduced vibration, which improves edge quality and can lower the frequency of secondary deburring operations compared with two‑flute alternatives.
