150mm Countersink Set DIN 373 HSS 3-Flute Spiral-Grooved With Fixed Pilot, M3–M10, 6-Piece - TECWERK

Take advantage of a hard-wearing HSS geometry and a three‑flute spiral design for consistent, burr‑free chamfering; the fixed pilot pin and M3–M10 range ensure centred starts and reduced rework. Order the set via Metav Werkzeuge or consult the team for application advice.

TECWERK Replacement Countersink Set DIN 373 – HSS, 3‑Flute, M3–M10 (6‑piece)

A TECWERK replacement countersink set engineered for precise chamfering and clean thread starts across metric sizes in workshops and light production environments

• HSS 3‑flute spiral design
• Fixed pilot pin for centred operation
• Covers threads M3–M10
• Supplied in durable plastic cassette

Consistent thread starts through centred pilot guidance

The three‑cut geometry and fixed pilot pin deliver reliable centring for each chamfer, which reduces the risk of misaligned thread entries and minimises rework. Built to DIN 373 dimensions, the toolset provides repeatable results on threaded holes so machining tolerance is preserved and subsequent tapping operations run smoothly. The HSS cutting material maintains a sharp edge for a predictable finish without excessive force, supporting steadier cycle times and fewer scrap parts.

Reduced downtime with robust spiral‑fluted cutters and storage

The spiral‑fluted design evacuates material evenly, improving chip flow and avoiding clogging during serial work. With a cylindrical shank and standardised mounting interface the cutters interchange quickly, while the 6‑piece set in a protective plastic cassette keeps tools organised and ready for use. This configuration cuts changeover time and helps maintain a tidy toolroom, contributing to steady throughput and lower handling errors.

Broad metric coverage for versatile workshop use

Covering M3–M10 thread sizes in one set eliminates the need for multiple single cutters and simplifies inventory management. The combination of three cutting edges and HSS construction balances edge life with ease of resharpening, making the set suitable for frequent chamfering tasks in mixed‑use environments. Clear labelling in the cassette supports rapid selection, while the standard compliance guarantees compatibility with existing tooling systems and fixtures.

FAQ

Which metric thread sizes are covered by this set?
The TECWERK replacement countersink set covers thread sizes from M3 to M10 and is supplied as SKU 2000865360NW.

What material are the cutters made from and what does that mean for durability?
The cutters are manufactured from HSS, which offers a good balance of toughness and wear resistance for chamfering tasks, extending tool life in routine workshop applications.

How many pieces are included and how are they stored?
The delivery contains a 6‑piece set stored in a durable plastic cassette for organised transport and straightforward identification.

Is a pilot pin included and what is its benefit?
Yes, the set features a fixed pilot pin that ensures centred chamfering to reduce the likelihood of cross‑threading and to support consistent thread engagement.

Does the set conform to any standard?
The tooling conforms to DIN 373 specifications and uses a three‑flute spiral geometry for reliable chip evacuation and finish quality.
