Countersink DIN 335 C, 90° Ø 8.3 mm – HSS TiN, 3 flutes (TECWERK)

Countersink DIN 335 C, 90° Ø 8.3 mm – HSS TiN, 3 flutes (TECWERK) is a precision tool for chamfering and deburring holes in a range of engineering materials

• DIN 335 C geometry for industrial chamfering
• High-speed steel base material with TiN coating
• Three‑flute design for smooth, chatter‑free cutting
• Cylindrical shank for stable clamping

Precise chamfers with industrial standard geometry

The three‑flute tool follows DIN 335 C and offers a true 90° countersink angle, delivering consistent chamfer dimensions suitable for subsequent fastening or visual finishing. Manufactured from HSS, the tool maintains edge integrity under typical workshop demands, while the TiN coating reduces friction and extends service intervals. This combination supports predictable machining results and reduces the need for rework, which is essential for process reliability in production environments.

Smooth cuts and higher productivity through flute design

Thanks to the 3‑flute geometry, the tool achieves a chatter‑free cut, noticeably improving surface quality at the chamfer and reducing vibration transmitted to the workpiece. The specified feed performance — 0.09 mm/rev in steel up to 500 N — gives a clear baseline for machining parameters, enabling planners to balance speed and finish. The result is a time‑efficient operation with fewer interruptions for adjustments, contributing directly to throughput improvements on the shop floor.

Durable finish and easier handling in daily use

The TiN coating combines lower adhesion tendency with enhanced wear resistance, which supports longer tool life even when processing abrasive alloys. The cylindrical shank simplifies clamping in standard toolholders and reduces setup time, so the tool is ready for rapid changeovers. These attributes make the tool well suited to both repetitive production tasks and repair jobs where consistent chamfers are required without compromise.

Clear suitability across common materials and simple feed guidance

Intended for use on steel, cast iron and non‑ferrous metals, the countersink adapts to a broad set of workshop applications from fabrication to maintenance. The design ensures effective chip evacuation and consistent geometry even on small bore holes, while the given feed figure provides a starting point for optimisation. For unfamiliar materials or special alloys, consult material‑specific cutting data to match speed and feed to the component’s properties.
