TECWERK 90° Countersink DIN 335 C — 31 mm, HSS, 3-flute

TECWERK 90° Countersink DIN 335 C — 31 mm, HSS, 3-flute is a precision tool designed for clean countersinking and burr removal in a wide range of workshop materials

• HSS countersink, DIN 335 C, 90° angle
• Three-flute design for chatter-free cutting
• Cylinder shank for secure toolholding
• Suitable for steel, cast iron and non-ferrous metals

Consistent, accurate chamfers for repeatable assemblies

Built from HSS and shaped to the DIN 335 C specification, the tool delivers a repeatable 90° chamfer that improves assembly fit and fastener seating. The 31 mm diameter provides a generous contact area for common bolt and screw sizes while maintaining concentricity. As a result, downtime caused by reworking misaligned countersinks is reduced and components meet their functional tolerances more reliably.

Faster, smoother cutting thanks to three flutes

The three-flute geometry is engineered to produce a chatter-free cut, which stabilises the machining process and improves surface finish. For workshop planners this translates into fewer rejects and less manual deburring. The tool is specified with a practical feed guideline — 0.22 mm/rev at up to 500 N feed in steel — which supports predictable cycle times when integrated into production or repair workflows. This numeric guidance helps set machining parameters without prolonged trial runs.

Secure handling and broad material capability

A cylinder shank ensures reliable clamping in standard toolholders so the cutter remains true under load. The design is suitable for countersinking and deburring holes in steel, cast iron and non-ferrous metals, enabling one cutter to cover multiple tasks in mixed-material shops. The robust construction and geometry reduce vibration and wear, supporting longer service life and fewer tool changes — a practical advantage for small to medium production batches and maintenance departments.
