TECWERK Countersink DIN 335 C, 90° – HSS nano, 8.3 mm, 3-flute

TECWERK Countersink DIN 335 C, 90° – HSS nano-coated, three-flute tool for precision deburring and countersinking in a wide range of metals and plastics.

• 90° DIN 335 C geometry for standard countersinks
• HSS with nano coating for increased wear resistance
• Three-flute design for smooth, stable cutting
• Shank with three flats from nominal Ø 8.3 mm

Precision cutting that reduces effort and increases output

The HSS body combined with a specialised nano coating and optimised chip-space geometry results in significantly lower feed forces, which reduces required machine power and minimises chatter. This refined design enables up to 30% faster countersinking and an extremely quiet run, so production lines operate more smoothly and with fewer interruptions. The DIN 335 C 90° geometry ensures consistent chamfer profiles, making the tool suitable for both series production and manual finishing tasks.

Longer tool life across metals and plastics

A variable relief and a carefully developed chip-spiral parameter provide very high wear resistance and hot hardness, delivering up to 60% longer tool life under comparable conditions. The cutter is right-hand cutting and is optimised for a broad material spectrum including steel, stainless and heat-resistant steels, aluminium, brass and plastics. For demanding batches, the combination of material resilience and coating stability offers measurable savings in tool changes and downtime.

Practical handling and reliable machine integration

The shank is supplied with three flats from nominal Ø 8.3 mm, improving grip in the chuck or collet and preventing slippage during high-torque operations. The three-flute geometry balances chip evacuation with surface finish, producing an optimised countersink and reducing the need for secondary operations. Recommended feed guidance for steel (up to 800 N) is 0.15 mm/rev, offering a clear baseline for process planning while allowing adjustments for specific machines or materials.

FAQ

What materials can this countersink process reliably?
The TECWERK countersink is suitable for steel, stainless and heat-resistant steels, aluminium, brass and various plastics, thanks to its HSS substrate and nano coating.

How does the nano coating benefit production runs?
The nano coating on the cutter improves wear resistance and hot hardness, which in turn extends service life and reduces the frequency of tool changes during continuous production.

Is there a recommended feed value for steel?
For steel under loads up to 800 N, a feed of 0.15 mm/rev is recommended as a starting point; the TECWERK countersink maintains stable performance at this setting.
