TECWERK 60° tapered countersink DIN 334 C, Ø20 mm, HSS, 3‑flute

The TECWERK 60° tapered countersink DIN 334 C Ø20 mm is a precision countersink intended for burr removal, smooth chamfering and flush countersinking in steels, castings and non‑ferrous and light metals.

• HSS construction for long tool life
• 60° taper for standard countersinking
• 3‑flute geometry for smooth, burr‑free cuts
• Cylindrical shank, right‑hand cutting

Consistent burr‑free finishing that reduces rework

The 60° taper combined with a 3‑flute cutting geometry produces a controlled chip flow and a uniform chamfer, resulting in burr‑free edges that minimise follow‑up finishing. Manufactured from HSS to the DIN 334 C specification, the cutter is built for repetitive production tasks where a clean seating surface is essential. This reliability translates into fewer rejects and lower rework times for assembly operations that demand accurate countersinks.

Robust tool life and dependable cut behaviour

Constructed in high‑speed steel and designed with three cutting edges, the tool offers a balance of toughness and sharpness that withstands intermittent production stresses. The cylindrical shank and right‑hand cutting ensure stable clamping and consistent rotational direction in standard drill holders. For best results, the tool performs optimally at reduced cutting speeds; a recommended feed in steel (up to 500 N) is 0.2 mm/rev, which supports predictable tool wear and repeatable surface quality in series work.

Wide material compatibility to streamline tooling

The design is suitable for machining steel, castings, and a range of non‑ferrous and light metals, allowing one tool to cover multiple tasks and reduce tool changes. The combination of HSS material and the three‑edge geometry handles softer alloys like aluminium and brass without excessive burring, while still delivering acceptable performance in typical carbon steels. Where gentle chamfering and deburring are required, this countersink provides a versatile, production‑oriented solution.

Easy integration into workshop processes

Conforming to DIN 334 C standards and fitted with a cylindrical shank, the cutter integrates seamlessly into common drilling and countersinking setups, reducing set‑up time and simplifying inventory management. The geometry promotes low vibration and improved surface finish, supporting automated or manual operations alike. Specifying a standardised countersink minimises the number of special‑purpose tools and supports a leaner workshop tooling concept.
