TECWERK Countersink DIN 335 C Ø31 mm, 90° — HSS, TiAlN, 3‑flute

A TECWERK countersink DIN 335 C engineered for accurate countersinking and deburring of drilled holes in steel, cast iron and non‑ferrous metals.

• 90° countersink for standard chamfers
• TiAlN coating for extended tool life
• Three‑flute geometry for chatter‑free cutting
• Cylindrical shank for stable toolholding

Precision finish and material versatility for reliable chamfers

The DIN 335 C design and Ø31 mm diameter provide a consistent chamfer profile, making the tool suitable for routine production and rework alike. Manufactured in HSS and enhanced with TiAlN, this countersink sustains cutting performance at elevated temperatures and maintains edge integrity, which reduces the need for frequent tool changes. The result is a predictable surface finish and fewer interrupted cycles when working with steel, cast iron or non‑ferrous metals.

Higher throughput through chatter‑free geometry and predictable feeds

The three‑flute configuration ensures balanced cutting forces and a chatter‑free operation, which helps to maintain concentricity and hole quality even at moderate feeds. With a recommended feed of 0.22 mm/rev in steel at cutting forces up to 500 N, the tool supports efficient material removal while preserving edge life. This combination of geometry and feed guidance translates into shorter cycle times and fewer rejects in batch work.

Robust construction and secure toolholding for consistent results

A cylindrical shank provides straightforward mounting in standard chucks and collets, delivering axial stability during countersinking. The tool’s composition in HSS offers toughness for interrupted cuts, while the TiAlN surface treatment increases wear resistance and reduces built‑up edge formation. Together these features provide a maintenance‑friendly option that keeps machine downtime to a minimum and supports repeatable quality across runs.

Practical fit for workshops and production environments

Designed for countersinking and deburring after drilling, the tool performs well in mixed‑material environments where quick changeovers are common. Its adherence to the DIN specification facilitates process planning and integration with existing toolsets. By combining thermal resistance and a balanced flute design, the countersink supports both small workshops and larger fabrication benches that prioritise predictable performance and low regrind rates.
