Conical countersink DIN 335 C Ø 16.5 mm — 90° HSS‑Co, 3 flutes (TECWERK)

The conical countersink DIN 335 C Ø 16.5 mm HSS‑Co is a precision cutting tool for countersinking and deburring holes in steel, cast iron and non‑ferrous metals, designed for industrial metalworking and workshop use

• DIN 335 C conical countersink, 90° angle
• Three‑flute design for chatter‑free cutting
• HSS‑Co for stainless and heat‑resistant steels
• Cylindrical shank for secure chucking

Consistent, measurable results for metalworking operations

The conical design, specified to DIN 335 C and a 90° seating angle, delivers predictable geometry for rivets, flat‑head screws and chamfers. Manufactured in HSS‑Co, the tool retains hardness at elevated temperatures, which extends tool life when working with tougher alloys. The Ø 16.5 mm cutting diameter combined with the three cutting edges produces a stable, low‑vibration cut; this minimises rework and helps maintain hole tolerances, translating directly into higher first‑pass yield on production and maintenance tasks.

Cutting geometry that reduces chatter and improves surface finish

The three‑flute arrangement ensures a balanced cut and continuous chip formation, resulting in a rattle‑free process and improved surface quality at the chamfer. The cobalt‑alloyed steel matrix (HSS‑Co) increases resistance to softening under heat, making the tool suitable for stainless and heat‑resistant steels as well as conventional steels and cast materials. For shops seeking repeatable chamfer edges, this geometry reduces cycle‑time losses caused by tool marks and vibration, improving assembly fit and visual appearance.

Practical handling and compatibility with standard tooling

The cylindrical shank is compatible with common drill chucks and straight shank holders, enabling fast tool changes and straightforward integration into existing workflows. Recommended feed guidance in steel up to 500 N is 0.14 mm per revolution, which balances cutting efficiency and surface finish; this figure aids process planners and operators when setting feeds on manual or CNC machines. The countersink’s robust construction supports routine use in maintenance, fabrication and small‑batch production environments.

Where this countersink adds measurable value

Suited for de‑burring and countersinking operations in steel, cast iron and non‑ferrous metals, the tool is particularly valuable where corrosion‑resistant and heat‑resistant alloys are present. Reduced vibration and improved cut quality mean fewer rejected parts and less post‑processing, offering a tangible contribution to uptime and cost control. For workshops aiming to standardise on resilient cutting tools without complex tooling changes, this countersink offers a dependable, easy‑to‑implement option.

FAQ

What materials can this countersink be used on?
The conical countersink is suitable for steel, cast iron and non‑ferrous metals; the HSS‑Co grade extends capability to stainless and heat‑resistant steels when using the TECWERK countersink (SKU 2000865010NW).

Is the tool compatible with standard drill chucks?
Yes, the cylindrical shank allows secure mounting in conventional drill chucks and straight‑shank holders, making the TECWERK conical countersink straightforward to use in workshop settings.

What feed should be used for reliable results in steel?
For steel with cutting forces up to 500 N, follow the recommended feed of 0.14 mm per revolution to balance tool life and surface finish when using this countersink.

Does the three‑flute geometry affect finish quality?
The three‑flute design provides balanced cutting and continuous chip evacuation; as a result, surface finish and hole concentricity improve compared with fewer‑flute designs.
