6.3-25mm Countersink Set DIN 335C 90° HSS-Co TiAlN Spiral 5-Piece, Plastic Case - TECWERK

Fast, precise countersinking with extended tool life and significantly reduced cutting forces: the combination of HSS‑Co construction, TiAlN coating and spiral‑fluted geometry ensures cleaner holes and longer production runs; order directly via Metav Werkzeuge or consult their specialists for application guidance.

TECWERK Countersink Set DIN 335 C 90° (6.3–25 mm) — HSS‑Co, TiAlN, 5‑piece

The TECWERK Countersink Set DIN 335 C is a robust, spiral‑fluted countersink kit designed for precise 90° chamfering in a wide range of workshop materials, supplied as a five‑piece set in a plastic storage cassette

• HSS‑Co core with TiAlN coating, high wear resistance
• Spiral flutes for smooth, chatter‑free countersinking
• Three unequal convex cutting edges for precision
• 60% lower feed force and 50% lower radial force
• Five‑piece set in a durable plastic storage cassette

Reliable performance and extended tool life for continuous production

Manufactured with a high‑cobalt HSS core and enhanced by a TiAlN coating, the set is engineered to withstand elevated temperatures and abrasive conditions typical of mixed‑material machining. The coating reduces friction and helps maintain edge hardness, which translates to longer tool life and fewer tool changes on the shop floor. These properties support higher productivity and more predictable maintenance cycles, which is particularly valuable for production environments seeking to reduce downtime and tooling costs while maintaining consistent quality.

Precision results with markedly lower cutting forces

The spiral‑fluted design combined with three unequal convex cutting edges produces a round, burr‑reduced chamfer and helps to avoid chatter. Measurable performance improvements include 60% lower feed force and 50% lower radial force, leading to easier penetration, reduced load on the spindle and improved surface finish. This technical behaviour simplifies setup and can permit more stable feeds on smaller machines, making the toolset suitable for both in‑house workshops and light production lines aiming for repeatable, high‑quality countersinks.

Broad material compatibility for versatile workshop use

Conforming to DIN 335 C and featuring a 90° geometry, the set is suitable for processing a broad spectrum of materials: steel, stainless and heat‑resistant steels, aluminium, brass and plastics. The spiral flutes assist chip evacuation across these substrates, reducing the risk of clogging and enabling cleaner cutting action in softer as well as tougher materials. This versatility reduces the need for multiple dedicated tools and supports faster changeovers when different components are being processed on the same machine.

Practical supply and secure storage for organised workflows

Delivered as a five‑piece set in a secure plastic cassette, the countersinks are easy to store and locate, which speeds up tooling changes and supports orderly workshop practices. Size coverage from 6.3–25 mm permits common chamfering requirements to be handled with one compact kit. The case protects edges during transport and keeps selections visible and accessible on the tool trolley, contributing to reduced setup times and consistent part quality across shifts.
