TECWERK Countersink DIN 335 C 90° D6.3 HSS-Co – 3-flute countersink for steel, castings and non‑ferrous metals

The TECWERK Countersink DIN 335 C 90° D6.3 HSS‑Co is a precision three‑flute countersink engineered for smooth chamfering and deburring of drilled holes in a wide range of workshop materials.

• DIN 335 C, 90° countersink
• Three‑flute, chatter‑free cutting
• Cylindrical shank for stable clamping
• HSS‑Co for stainless and heat‑resistant steels

Deliver consistent, burr‑free holes with precision geometry

The tool’s DIN 335 C geometry and 90° chamfer angle ensure standardised countersinks suitable for most fastening tasks, while the nominal 6.3 mm diameter provides a compact option for small to medium holes. The three‑flute arrangement produces a chatter‑free cut by distributing cutting forces evenly; this reduces vibration and results in cleaner chamfers with minimal finishing work. The specified feed in steel up to 500 N of 0.09 mm/rev ensures predictable material removal — information that helps to set cutting parameters correctly and improve cycle time.

Optimised material compatibility for demanding workshops

Manufactured in high‑speed steel with a cobalt alloy option (HSS‑Co), the countersink is suitable for conventional and more challenging materials. The HSS grade offers reliable performance on steel, castings and non‑ferrous metals, while HSS‑Co increases red‑hardness and abrasion resistance for stainless and heat‑resistant steels. The cylindrical shank allows secure mounting in standard tool holders; as a result, the tool can be integrated into existing setups without toolholder modification, maintaining throughput and reducing setup time.

Reduce rework and rely on a consistent supply chain

With a design focused on stable cutting and reduced burr formation, this countersink delivers consistent results that lower rework rates and save operator time. The combination of robust geometry and wear‑resistant material reduces tool changes and supports sustained production runs. Procurement via Metav provides the reassurance of an experienced precision partner: Metav’s position as a quality filter in Europe, plus a broad catalogue and reliable logistics from Emmerich, supports uninterrupted workshop supply and predictable lead times.

FAQ

Is this countersink suitable for stainless steel?
Yes. The TECWERK Countersink DIN 335 C 90° D6.3 HSS‑Co is available in an HSS‑Co grade that is suitable for stainless and heat‑resistant steels.

What advantage does the three‑flute design provide?
The three‑flute geometry reduces vibration and delivers a chatter‑free cut, resulting in cleaner chamfers and less need for post‑process deburring when using this countersink.

Can the tool be used in standard collets and holders?
Yes. The countersink features a cylindrical shank designed for secure clamping in common tool holders and collets.

What materials can be machined with the HSS version?
The HSS variant is suitable for steel, castings and non‑ferrous metals; for stainless and heat‑resistant alloys the HSS‑Co option is recommended.

What is the recommended feed in steel?
The technical specification indicates a feed in steel up to 500 N of 0.09 mm/rev for consistent cutting performance.
