TECWERK Countersink set DIN 335 C – HSS, 90° (6.3–25 mm)

The TECWERK countersink set DIN 335 C is a five-piece HSS tool kit designed for countersinking and deburring drilled holes in workshop and production environments

• DIN 335 C standard compliance
• 90° countersink angle for standard chamfers
• Three cutting edges for smooth finishing
• High-speed steel (HSS) for cutting performance

Consistent hole finish and reduced rework

The combination of a 90° countersink profile and three cutting edges produces clean, concentric chamfers that reduce secondary machining and fitting issues. The three-edge geometry evens out cutting forces, which leads to a more uniform surface and fewer burrs after drilling. For production environments where repeatable results matter, this set supports faster inspection cycles and lower scrap rates while maintaining reliable hole geometry.

Streamlined workshop workflow and secure storage

With five sizes spanning 6.3–25 mm, the set minimises tool changes and covers common countersinking requirements without unnecessary inventory. The kit is supplied in a compact plastic case that protects the cutters and keeps the set organised at the bench or in a tool trolley. This practical packaging helps shorten setup times and makes it simpler to track tooling on the shop floor, contributing to overall process efficiency.

Purpose and application explained

Designed specifically for the task of countersinking and deburring drilled holes, the cutters follow the DIN 335 C specification for consistent chamfer geometry. Countersinking prepares holes for flush fasteners and removes burrs that can impede assembly or compromise part fit. The HSS construction ensures the cutters retain cutting capability across standard workshop operations where moderate speeds and intermittent cutting are typical.

Standards, durability and operator benefits

Compliance with DIN 335 C gives machine shops and maintenance teams a clear reference for interchangeability and expected chamfer form, simplifying quality checks and documentation. The HSS material is a proven choice in cutting tools for its balance of hardness and toughness, delivering dependable performance across routine countersinking tasks. Operators benefit from straightforward handling and predictable cutting behaviour, which supports faster training and safer, more consistent work steps.
