TECWERK Conical countersink DIN 335 C — 25 mm, HSS with TiAlN, 3-flute

A TECWERK Conical countersink DIN 335 C engineered for precision chamfering and deburring of drilled holes in steel, cast iron and non‑ferrous metals

• DIN 335 C profile, 90° chamfer angle
• Three-flute design for rattle-free cutting
• TiAlN coating for increased tool life
• Suitable for steel, cast iron and non-ferrous metals

Precision chamfers with consistent, burr‑free results

The TECWERK countersink combines a three‑flute geometry with a 90° chamfer to produce clean, concentric chamfers and minimal burr formation. The multi‑cut design reduces vibration and delivers a rattle‑free cutting action, which translates into smoother surfaces and fewer secondary operations. The use of HSS substrate ensures toughness under intermittent cutting, while the TiAlN coating improves heat resistance and wear performance, extending tool life in high‑temperature conditions.

Reliable performance across typical workshop materials

Designed for general workshop and industrial use, this tool is suitable for chamfering and deburring in steel, cast iron and non‑ferrous metals. A version in HSS‑Co is noted for better performance on stainless and heat‑resistant steels where higher red hardness is required. The specified feed capability — 0.2 mm/rev in steel with cutting forces up to 500 N — provides a practical balance between material removal and surface finish. The cylindrical shank ensures secure clamping in conventional chucks and reduces run‑out for repeatable results.

Minimise downtime and simplify workflow

Conforming to DIN 335 C gives compatibility across standard tool holders and fixtures, simplifying replacement and inventory management. The robust combination of substrate and TiAlN coating reduces frequency of regrinds and tool changes, saving operator time and lowering production interruptions. Clear, verifiable technical data and standardised geometry support predictable outcomes and make this countersink a dependable choice for workshops seeking efficient, high‑quality chamfering.

FAQ

What materials can this countersink be used on?
The countersink is suitable for steel, cast iron and non‑ferrous metals; an HSS‑Co variant is available for stainless and heat‑resistant steels.

What does the TiAlN coating provide?
The TiAlN coating increases thermal resistance and wear performance, allowing longer tool life and improved performance at elevated cutting temperatures.

Is the geometry standardised for easy replacement?
Yes, the tool follows DIN 335 C with a 90° chamfer angle and cylindrical shank for straightforward replacement in standard holders.

What cutting parameters are recommended?
A practical guideline from the data indicates a feed in steel of 0.2 mm/rev at cutting forces up to 500 N for consistent results.

Does the three‑flute design improve surface finish?
The three‑flute layout reduces vibration and produces a rattle‑free cut, which helps achieve cleaner chamfers and reduces the need for secondary finishing.
