TECWERK Countersink Set DIN 335 C — HSS Nano, 90° geometry (6.3–25.0 mm)

A TECWERK Countersink Set DIN 335 C designed for high‑performance chamfering and deburring across metals and plastics in workshop and industrial applications

• HSS with Nano coating for high wear resistance
• 90° countersink geometry per DIN 335 C
• Three cutting edges for smooth, low-vibration cutting
• Reduced feed force, up to 60% longer tool life
• Supplied in a plastic case for organised storage

Faster, more efficient countersinking for production demands

The TECWERK countersink set combines HSS substrate and a specialised Nano coating to deliver tangible production benefits: the modified coating and flute geometry result in reduced feed force, which lowers spindle load and operator effort, while optimised chip evacuation enables up to 30% faster countersinking in comparable conditions. The three‑edge design provides a stable cut that translates into smoother operation and consistent cycle times, making the set particularly suitable for series work where throughput and repeatability are priorities.

Precision geometry for repeatable, burr‑free finishes

Built to DIN 335 C with a 90° countersink angle, the tools provide predictable chamfer dimensions for both clearance and screw seating operations. The variable back‑off (relief) reduces contact on the flank, which helps to prevent chatter and minimises burr formation on the workpiece edge. A shank with three flats from nominal Ø 8.3 mm ensures secure clamping and concentric running, contributing to a very quiet, low‑vibration cut and measurable improvements in surface quality when working on assembly components.

Versatile machining across common workshop materials

These countersinks are engineered for a wide range of materials including steel, stainless and heat‑resistant steels, aluminium, brass and plastics. High hot hardness and wear resistance are achieved through a combination of flute parameter optimisation and the Nano finish, so the tools maintain cutting performance under increased temperatures and extended use. This versatility makes the set a pragmatic choice for maintenance shops, toolrooms and small production lines that handle mixed‑material batches.

Practical handling and organised storage for the shop floor

The set covers a size range of 6.3–25.0 mm and is supplied as a five‑piece kit in a durable plastic cassette for tidy storage and rapid tool selection. Right‑hand cutting geometry suits standard spindle directions, while the three cutting edges reduce surface irregularities and permit lower feed rates without sacrificing productivity. The compact case protects the inserts and keeps the workshop orderly, supporting fast changeovers and reducing downtime between operations.

FAQ

What size range does the set cover?
The countersink set covers sizes from 6.3 mm to 25.0 mm and includes five precision countersinks for common workshop needs.

Which materials can be machined with these countersinks?
The TECWERK countersinks are suitable for steel, stainless and heat‑resistant steels, aluminium, brass and a variety of plastics due to their HSS core and Nano coating.

How does the Nano coating improve performance?
The Nano coating increases wear resistance and hot hardness, which prolongs life and helps maintain cutting performance during longer runs with the TECWERK tools.

Is the geometry suitable for production use?
Yes. The 90° DIN 335 C geometry combined with three cutting edges and optimised flute parameters ensures repeatable chamfers and low vibration for series production.

Are the tools easy to clamp securely?
A shank with three flats from nominal Ø 8.3 mm provides secure clamping and improved concentricity for quieter, more precise machining.
