TECWERK countersink DIN 335 C — 90° · 31 mm · HSS TiAlN

The TECWERK countersink DIN 335 C is a precision 90° countersinking tool designed for clean deburring and chamfering of holes in a wide range of metals.

DIN 335 C geometry for standardised chamfers Three cutting edges for chatter‑free machining TiAlN coating for improved heat resistance Cylindrical shank for secure mounting

High‑productivity countersinking with stable cutting

The standardized DIN 335 C profile and the three cutting edges produce a consistently shaped chamfer and a chatter‑free cutting action. This geometry reduces the risk of burring and the need for post‑operation rework, which shortens cycle times in production environments. The tool’s design suits serial processing as well as precision repair work, offering predictable results when used in quality‑controlled setups.

Wear resistance and thermal stability for longer runs

Made from HSS with a TiAlN surface treatment, the tool resists thermal softening and wear during sustained cutting. The coating lowers friction at the cutting zone and increases oxidation resistance, which extends service life compared with uncoated variants. For machining stainless and high‑temperature alloys, the HSS‑Co option offers increased red‑hardness and maintains cutting performance under demanding conditions.

Practical mounting and feed guidance for reliable results

A cylindrical shank guarantees concentric clamping and simple integration into commonly used holders and machines, reducing setup time. Recommended practical data includes a feed in steel up to 500 N of 0.22 mm/rev, which balances surface finish and tool life for typical workshop steels. The tool is intended for countersinking and deburring operations in steel, cast components and non‑ferrous metals, delivering precise chamfers that aid assembly and welding preparation.

FAQ

What materials can be processed with this countersink?
The TECWERK countersink DIN 335 C (SKU 2000865229NW) is specified for steel, cast parts and non‑ferrous metals; an HSS‑Co variant extends suitability to stainless and heat‑resistant steels.

How does the TiAlN coating benefit the tool?
The TiAlN coating on the countersink reduces friction and raises heat resistance, which keeps cutting edges sharper for longer and improves performance in longer machining runs.

Is the tool suitable for production runs on CNC machines?
Yes — the three‑edge geometry and cylindrical shank ensure stable clamping and chatter‑free cutting, making the tool suitable for repeated operations in CNC and production settings.

What feed rate should be used as a starting point?
A practical starting point is 0.22 mm/rev for steel up to a cutting force of 500 N; this provides a balance between surface quality and tool life.

Can this countersink be used for final chamfering before assembly?
Indeed — the DIN 335 C profile produces standardised chamfers that facilitate assembly, deburring and preparation for welding.
