Countersink DIN 335C 90° Ø25 mm — TECWERK HSS TiN, 3‑flute

The Countersink DIN 335C 90° Ø25 mm is a high‑speed steel, TiN‑coated 3‑flute cutting tool designed for chamfering and deburring holes in metalworking workshops and production environments

• HSS with TiN coating for extended life
• 90° chamfer angle for standardised countersinking
• Three‑flute geometry for vibration‑free cutting
• Suitable for steel, cast iron and non‑ferrous metals

Consistent chamfers with industrial endurance

The combination of HSS construction and a TiN coating offers a reliable balance between hardness and wear resistance, making the tool suited for repeated use under production conditions. Conformance to DIN 335C ensures dimensional predictability so that chamfers remain consistent across batches. The result is fewer rejected parts and reduced need for rework, which supports steady throughput and predictable process planning.

Faster, cleaner processing with reduced chatter

The three‑flute design delivers a rattle‑free cut, splitting chips into smaller segments and smoothing chip evacuation. This geometry, together with the 90° chamfer angle, shortens cycle times for deburring and countersinking operations while maintaining a clean edge. For steel work under loads up to 500 N a feed of 0.2 mm/rev has been specified, providing a practical reference for setting machining parameters on conventional drilling and milling machines.

Broad material compatibility for versatile workshop use

Engineered for chamfering and deburring of steel, cast iron and non‑ferrous metals, the tool is a versatile addition to general workshop tooling. The cylindrical shank suits standard tool holders and allows quick mounting on conventional machines. Reduced vibration from the tool geometry improves surface finish and lowers the likelihood of tool‑induced damage, increasing confidence when processing delicate or critical components.

Standardised format for seamless production integration

Supplied in a standard Ø25 mm diameter and manufactured to recognised specifications, the countersink integrates easily into tool sets and inventory systems. The combination of robust materials and surface treatment helps prolong service life, reducing the frequency of replacements and contributing to cost‑efficient operation. Maintenance is straightforward: regular inspection of cutting edges and appropriate machine settings preserve performance and repeatability.

FAQ

What materials can be processed with this countersink?
The TECWERK countersink is suitable for steel, cast iron and non‑ferrous metals, making it a versatile tool for general metalworking tasks.

What is the chamfer angle and why is it important?
The tool has a 90° chamfer angle, which is a common standard for creating neat, standardised chamfers and preparing holes for fasteners.

How does the TiN coating benefit tool life?
The TiN coating reduces wear and improves heat resistance, extending the service life of the HSS cutting edges under repeated use.

Is the three‑flute design better than two flutes for countersinking?
The three‑flute geometry offers improved chip control and a rattle‑free cut, which enhances surface finish and reduces vibration compared with fewer flutes.

What feed rate should be used as a guideline?
For steel under loads up to 500 N a feed of 0.2 mm/rev is indicated as a practical reference for setting machining parameters.
