Take advantage of the combination of HSS construction, TiN coating and a three‑flute geometry for efficient, chatter‑free countersinking and reliable deburring in mixed workshop environments; order directly via Metav Werkzeuge or contact the consultants for technical advice.

TECWERK Countersink DIN 335 C — 90° · 10 mm · HSS with TiN, 3 flutes

The TECWERK Countersink DIN 335 C is a 90° conical countersink designed for precise chamfering and deburring of drilled holes in steel, cast iron and non‑ferrous metals.

• HSS body with TiN coating
• 90° conical angle for standard countersinks
• Three‑flute design for chatter‑free cutting
• Suitable for steel, cast iron and non‑ferrous metals

Precise, standard‑compliant countersinking for reliable assembly

The tool is manufactured to DIN 335 C and offers a 90° conical geometry with a nominal 10 mm diameter, delivering consistent chamfers that ease bolt seating and finishing operations. The standardised angle and dimensioning help to reduce assembly tolerances and rework, while the combination of countersinking and deburring in a single operation shortens cycle times. This behaviour is particularly valuable where repeatability and interchangeability are required across batches.

High productivity through optimised flute geometry

A three‑flute configuration ensures a balanced cut and significantly reduces vibration compared with two‑flute designs, resulting in a chatter‑free cut and improved edge quality. The tool is specified for a recommended feed in steel at load levels up to 500 N with a feed of 0.12 mm/rev, which supports stable material removal and predictable surface finish. The cylindrical shank is compatible with common tool holders, enabling quick changeover on standard workbenches and machines.

Durable coating and material for extended service life

Made from HSS and finished with a TiN coating, the countersink combines toughness with reduced friction. The coating increases wear resistance and helps dissipate heat at the cutting edge, extending tool life and maintaining consistent surface quality over prolonged production runs. For workshops aiming to lower tooling costs per part, this balance of hardness and surface treatment offers measurable benefits in uptime and consumable replacement intervals.

Practical guidance for workshop integration

For long service life, use secure clamping and moderate spindle speeds appropriate for high‑speed steel tooling; avoid excessive feed or lateral forces that could blunt the cutting edges. The tool performs well when returning clean chamfers after drilling; finishing can ordinarily be completed in one pass depending on material and hole size. The TECWERK countersink is particularly suited to applications requiring quick deburring and reliable chamfer geometry in mixed‑material production runs.

FAQ

What materials is this countersink suitable for?
The TECWERK countersink (DIN 335 C, Ø 10 mm) is suitable for steel, cast iron and non‑ferrous metals, as stated in the technical specification.

How many flutes does the tool have and why does that matter?
This countersink has three flutes; the triple‑flute geometry provides a more balanced cut and a chatter‑free finish compared with two‑flute designs.

What is the recommended feed for use in steel?
A recommended feed in steel at loads up to 500 N is 0.12 mm/rev, which supports controlled material removal and consistent chamfer quality.

Does the TiN coating improve tool life?
Yes. The TiN coating reduces friction at the cutting edge and improves wear resistance, extending the service life of the HSS tool under typical workshop conditions.

Which standard does this countersink comply with?
The countersink conforms to DIN 335 C, ensuring standardised angle and geometry for repeatable countersinking operations.
