TECWERK 90° Countersink DIN 335 C, Ø 8.3 mm — HSS‑Co, 3‑Flute

The TECWERK 90° Countersink DIN 335 C is a precision cylindrical‑shank countersink designed for reliable deburring and countersinking of drilled holes in steel, cast iron and non‑ferrous metals.

• 90° cutting angle for standard countersinking
• HSS‑Co for heat and wear resistance
• Three‑flute design for rattle‑free cutting
• Cylindrical shank for secure toolholding

Consistent hole quality through chatter‑free cutting

A three‑flute geometry produces a rattle‑free cutting action that reduces vibration and secures a smooth bore and chamfer finish. The result is less rework and faster throughput in repetitive operations, with the design optimised for steady feed and a predictable surface quality. Thanks to the 90° tip geometry and adherence to DIN 335 C, the tool produces standard countersink profiles suitable for assembly and fastening processes.

Durable performance on demanding materials

Manufactured in HSS‑Co, the countersink offers improved resistance to heat and wear compared with standard high‑speed steels, extending tool life during continuous use. It is suitable for steel, cast iron and non‑ferrous metals, and is also capable of handling tougher stainless and heat‑resistant steels where increased hardness and temperature resistance are required. For machining in steel at cutting forces up to 500 N, a recommended feed of 0.09 mm/rev supports efficient material removal without compromising tool life.

Secure clamping and repeatable results for production use

The cylindrical shank provides reliable seating in collets and chucks, enabling secure toolholding and consistent concentricity when used in handheld drills or machining centres. This mechanical stability minimises run‑out and ensures repeatable chamfer geometry across batches, supporting quality control and reducing the need for manual finishing. The combination of standardised dimensions and robust shank design means straightforward integration into existing tool inventories.

Versatile and straightforward for workshop and on‑site tasks

Designed for both industrial workshops and maintenance departments, the countersink handles common deburring and countersinking tasks with minimal setup. The tool’s geometry and material selection balance cutting performance with ease of use, making it suitable for intermittent hand‑held operations as well as higher‑volume production. Single‑piece packaging supports rapid replenishment of consumables and straightforward stock management.
