Countersink set DIN 335 C 90° (6.3–20.5 mm) – TECWERK, HSS nano-coated

A Countersink set DIN 335 C 90° (6.3–20.5 mm) designed for precision countersinking and chamfering in steel, stainless and non-ferrous materials across production and workshop environments

• HSS with nano coating for increased wear resistance
• Three cutting edges for smooth, precise countersinking
• Up to 60% longer tool life
• Supplied in robust plastic case

Faster, more efficient countersinking for production use

The set is based on DIN 335 C geometry with a 90° countersink angle and three cutting edges, which reduces thrust and produces a consistent surface finish. The combination of HSS substrate and a nano coating lowers friction in the cutting zone; this results in lower feed force requirements and up to 30% faster countersinking speeds in many applications. For production planners and purchasing, these characteristics translate directly into shorter cycle times and reduced spindle load, improving throughput without major process changes.

Wide material compatibility and predictable results

The tool set is suited to a broad range of materials: from mild and alloyed steel to stainless and heat-resistant steels, plus aluminium, brass and common plastics. The three-edge design and optimised chip space help avoid clogging when machining softer alloys and avoid excessive heat when cutting tougher grades. The specified geometry ensures reliable, repeatable chamfer quality for fastening operations and cosmetic edges, making the set suitable for machine shops, fitting lines and maintenance departments that require consistent hole preparation.

Secure clamping, durable design and reduced downtime

Design features include a shank with three flats from nominal Ø 8.3 mm for positive clamping in chucks and holders, a variable relief that balances cutting action across the edge, and specially developed chip-space parameters that enhance wear resistance and hot hardness. The set is supplied in a practical plastic case for organised storage and tool protection, reducing tool-change time and the risk of damage. Together, these design choices cut the frequency of replacements and lower overall tooling costs while maintaining high-quality countersinks.

FAQ

What materials can be countersunk with this set?
The TECWERK countersink set is suitable for steel, stainless and heat-resistant steels, aluminium, brass and many plastics, as stated in the product data.

How does the nano coating affect performance?
The nano coating reduces friction and heat at the cutting edge, improving wear resistance and contributing to the reported increase in tool life for the TECWERK countersink set (SKU 2000865188NW).

Why choose a three-edge design?
A three-edge geometry gives a smoother cutting action and lower thrust forces compared with two-edge countersinks, leading to a better surface finish and quieter operation for precision tasks.

Is the set easy to clamp securely in holders?
Yes. The tools feature a shank with three flats from nominal Ø 8.3 mm, which ensures positive clamping and reduces slippage in standard chucks and collets.

What is included in the packaging?
The set is supplied as a 6-piece collection in a plastic case for organised storage and transport.
