7mm Countersink 90° HSS Three-Point, 3-Flute Cylindrical Shank For Countersinking And Deburring In Steel, Casts, Non-Ferrous Metals - TECWERK

Smooth, chatter‑free countersinking for steel, cast iron and non‑ferrous metals is achieved by combining HSS construction with a three‑cutting‑edge 90° geometry; order the tool via Metav Werkzeuge or request application advice from their specialists.

TECWERK Countersink DIN 335 C 90° D.7mm HSS Z.3 — 3‑edge countersink with cylindrical shank

The TECWERK Countersink DIN 335 C 90° D.7mm HSS Z.3 is a high‑speed steel countersink designed for reliable deburring and countersinking of holes in common engineering materials such as steel, cast iron and non‑ferrous metals.

HSS construction for heat resistance and durability
90° countersink angle for standard fittings
Three cutting edges for chatter‑free cuts
Cylindrical shank for secure clamping

Consistent, chatter‑free cutting for reliable production

The combination of HSS material with a three‑cutting‑edge design delivers a stable, chatter‑free cutting action that reduces the risk of rework and improves surface finish. In practical terms, the geometry minimises vibration during countersinking, which supports faster cycle times and more consistent hole chamfers. The tool’s compliance with DIN 335 C ensures repeatable results when integrated into standard production routines.

Clear suitability across common engineering materials

This countersink is engineered specifically for countersinking and deburring holes in steel, cast iron and non‑ferrous metals, providing a single‑tool solution for mixed‑material workshops. The 90° angle matches standard flathead and countersunk fastener profiles, simplifying assembly preparation. The cylindrical shank allows secure clamping in conventional drill chucks and holders, making tool changes straightforward and keeping downtime to a minimum.

Measured performance that supports process planning

Quantified performance data enables confident process planning: the cutter is specified for a feed in steel up to 500 N at approximately 0.09 mm/rev, offering a practical reference for setting feed rates in manual or machine operations. The DIN 335 C specification and the robust HSS composition make the tool suitable for routine workshop use, where consistent countersinking quality is required without complex tooling changes.
