6.3-25mm Countersink Set DIN 335C 90° HSS Nano Coated 5-Piece, Plastic Case - TECWERK

Take advantage of the combination of HSS construction, a Nano coating and optimised flute geometry for faster, longer-lasting countersinking with less feed force; order the set via Metav Werkzeuge or contact our consultants for application advice.

TECWERK Countersink Set DIN 335 C 90° — HSS Nano, 5-piece (6.3–25.0 mm)

The TECWERK Countersink Set DIN 335 C is a precision 5-piece HSS set, Nano-coated and designed for high-performance countersinking in a wide range of metals and plastics.

• HSS with Nano coating for high wear resistance
• DIN 335 C profile, 90° countersink angle
• 3 cutting edges for smooth, quiet running
• Plastic case for organised storage

Faster machining and prolonged tool life for production environments

The combination of HSS base material and a specialised Nano coating reduces friction and increases heat resistance, resulting in up to 60% higher tool life and up to 30% faster countersinking under comparable conditions. These cutters require significantly less feed force, which lowers spindle load and helps maintain cycle times during repetitive operations. The coating and flute geometry also contribute to improved hot hardness, so the cutters remain effective throughout longer runs and in continuous production.

Smooth running, better surface quality and quieter operation

Three optimised cutting edges and a variable relief produce a balanced cutting action that reduces vibration and chatter. The result is a consistently clean countersink finish, reduced burr formation and an extremely quiet running behaviour on the machine. For applications where surface quality and repeatability matter, the balanced geometry minimises rework and inspection time while delivering predictable results on each hole.

Broad material compatibility and secure clamping for shop versatility

Designed to machines standards with a DIN 335 C profile and a 90° seating angle, the cutters are suitable for machining steel, stainless and heat-resistant steels, aluminium, brass and various plastics. A shank with three flats from nominal Ø 8.3 mm ensures secure clamping in chucks or collets, preventing slippage at higher speeds. Right-hand cutting and the optimised flute parameters enable reliable chip evacuation across different materials, supporting a wide range of workshop tasks from maintenance to series production.

Practical set range and tidy workshop handling

The five sizes covering 6.3–25.0 mm reduce the need for frequent tool changes, while the robust plastic cassette keeps cutters organised and protected between jobs. Variable relief and the specially developed flute geometry not only extend service life but also make the set a practical choice for both specialist toolrooms and general workshop use. The right-hand cutting direction and consistent DIN profile simplify process planning and ensure interchangeability with standard fasteners and fixtures.

FAQ

What size range is included in the set?
The set contains five countersinks covering 6.3–25.0 mm, supplied in a plastic cassette for organised storage.

Which materials can be machined with these countersinks?
The TECWERK countersinks are specified for steel, stainless and heat-resistant steels, aluminium, brass and various plastics, thanks to the HSS substrate and Nano coating.

How does the Nano coating benefit the countersinks?
The Nano coating improves wear resistance and hot hardness, reducing friction and extending the cutters' service life for longer production runs.

Is the shank suitable for secure clamping in standard chucks?
Yes — the shank has three flats from nominal Ø 8.3 mm, enabling secure clamping in chucks or collets to prevent slippage.

What performance improvements can be expected compared with conventional countersinks?
Due to the optimised flute geometry and coating, users can expect reduced feed force, up to 60% longer tool life and up to 30% faster countersinking under comparable machining conditions.
