TECWERK 90° Countersink DIN 335C — D 10.4 mm, HSS Nano, 3‑flute

The TECWERK 90° Countersink DIN 335C is a precision countersinking tool designed for reliable chamfering and deburring in metalworking and general workshop production.

• HSS Nano coating for high wear resistance
• 90° DIN 335C geometry for accurate countersinks
• 3‑flute design for smooth, quiet operation
• Reduced feed force; up to 60% longer tool life

Consistent chamfers and reliable seating for fast assembly

The TECWERK 90° Countersink DIN 335C D 10.4 mm is engineered to deliver precision chamfers that ensure screw heads and rivets seat consistently. The standard 90° geometry conforms to DIN 335C and simplifies downstream assembly by producing predictable chamfer forms. The tool’s optimised cutting geometry reduces radial runout and produces a clean surface finish, which minimises manual rework and speeds component joining operations. Such repeatability supports quality control routines and reduces rejects on series parts.

Higher throughput with less effort and extended tool life

Designed for productivity, the tool requires significantly less feed force, enabling stable operation on smaller machines or handheld countersinking setups. The specially developed chip flute parameters, the variable relief, and the nano coating combine to increase wear resistance and thermal hardness—resulting in up to 60% longer tool life and up to 30% faster countersinking in comparable conditions. For machining steel under forces up to 800 N, a reference feed of 0.15 mm/rev is indicated, supporting efficient cycle times without compromising edge life. The net effect is fewer tool changes and higher overall equipment effectiveness.

Versatile material capability with secure clamping

The cutter is suitable for a broad range of materials: steel, stainless and heat-resistant steels, aluminium, brass and various plastics, making it a practical choice for mixed-production workshops. The shank features three flats from a nominal diameter of 8.3 mm, ensuring positive drive and secure clamping in standard chucks or collets; this reduces the risk of slippage and maintains concentricity during high-speed countersinking. The right-hand cutting action and three‑cutter layout also support an extremely smooth, quiet running behaviour that benefits both operator comfort and surface quality.

Clear application guidance for dependable results

The cutter is a 3‑cutter, right-hand countersink manufactured to DIN 335C principles and fitted with an HSS substrate and a nano coating for enhanced performance. Use within the stated feed conditions for steel up to 800 N at approximately 0.15 mm/rev to balance surface finish and tool life. The variable relief assists in chips evacuation and reduces heat build-up, but consistent monitoring of cutting edges is recommended to determine the ideal regrind or replacement interval for specific production demands. Suitable for both production benches and tool rooms where dependable chamfering is required.

FAQ

What materials can this countersink machine handle?
The countersink is suitable for steel, stainless and heat‑resistant steels, aluminium, brass and various plastics; the TECWERK countersink (SKU 2000865177NW) is specified for these material groups.

What is the exact geometry and size of the tool?
The cutter has a 90° countersink angle in accordance with DIN 335C and a nominal diameter of 10.4 mm.

How does the nano coating affect performance?
The nano coating on the HSS substrate increases wear resistance and thermal hardness, leading to longer tool life and more stable cutting at elevated temperatures compared with uncoated tools.

Is the tool suitable for handheld use or only machine tools?
The three‑flat shank from nominal Ø 8.3 mm provides secure clamping, making the cutter suitable for use in production machines and in secure handheld setups where the chuck or collet supports that shank form; appropriate feed control is advised.

What feed rate should be used for steel applications?
A reference feed for steel at cutting forces up to 800 N is 0.15 mm/rev; actual feeds should be adjusted according to machine stiffness, material batch and surface finish requirements.
