TECWERK 90° countersink DIN 335 C, 12.4 mm — HSS‑Co, 3‑flute

The TECWERK 90° countersink DIN 335 C is a cylindrical‑shank countersinking cutter designed for precise chamfering and deburring of holes in steel, castings and non‑ferrous metals.

• DIN 335 C 90° geometry
• HSS‑Co for heat‑resistant steels
• Three‑flute rattle‑free cutting

Precise chamfering that reduces rework and improves fit

The DIN 335 C 90° geometry delivers consistently accurate chamfers, making the tool ideal for preparation of fastener seats or removing burrs after drilling. The three‑flute arrangement produces a rattle‑free cutting action, which visibly improves surface finish and reduces the need for secondary deburring operations. For production environments and maintenance workshops alike, the result is fewer rejects and shorter downstream processing times.

Durable cutting performance for demanding materials

Manufactured in HSS‑Co, the cutter offers elevated hardness and thermal resistance compared with standard high‑speed steel, enabling reliable cutting of stainless and heat‑resistant steels as well as conventional steel and cast materials. With a specified feed of 0.14 mm/rev in steel up to 500 N, the tool balances material removal rate and tool life for stable machining. The cylindrical shank ensures secure clamping in standard holders and steady concentricity during countersinking.

Designed for seamless workshop integration and consistent results

This countersink is intended for straightforward use in tool rooms and industrial production: the geometry and material combination support repeatable chamfering and deburring across batches. Use in machines or handheld holders that accept a cylindrical shank maintains process stability, while the rattle‑free flute design reduces vibration and noise at the cutting edge. Supplied as a single unit per pack, the tool is suited to both one‑off repairs and series work where consistent edge quality is required.

FAQ

Is the TECWERK 90° countersink suitable for stainless steel?
Yes. The TECWERK countersink, made in HSS‑Co, is specified for stainless and heat‑resistant steels as well as conventional steel, castings and non‑ferrous metals.

What clamping system is required for this tool?
The tool features a cylindrical shank and is compatible with standard cylindrical holders that accept the specified shank diameter.

How many flutes does this countersink have and why does that matter?
The cutter has three flutes, which produce a rattle‑free cutting action and a smoother chamfer, reducing burr formation and improving finish quality.

What feed rate is recommended for use in steel?
For steel up to 500 N, a feed of 0.14 mm/rev is indicated, balancing effective material removal with stable tool life.

Is the TECWERK 90° countersink suitable for series production?
Yes. The combination of HSS‑Co material, three‑flute design and DIN 335 C geometry makes the countersink appropriate for repeatable chamfering tasks in production environments.
