TECWERK 90° Countersink DIN 335 C — 6 mm, HSS, 3 flutes

TECWERK 90° Countersink DIN 335 C — 6 mm, HSS, 3 flutes is a compact tool for accurate chamfering and deburring in workshop and industrial environments

• DIN 335 C, 90° countersink
• High-speed steel (HSS) construction
• Three flutes for chatter-free cutting

Consistent, chatter-free chamfering for production use

The three‑flute geometry delivers a consistent, chatter‑free cut, reducing rework and improving hole finish in serial production. Built to the DIN 335 C profile and ground for uniform cutting action, the tool provides repeatable chamfers with minimal operator adjustments. The 90° angle is the standard for many fastening and countersinking applications, ensuring compatibility with common screw heads and assembly tolerances while supporting efficient deburring workflows.

Robust material and shank design for workshop handling

Manufactured from HSS, the countersink combines toughness with edge stability under moderate cutting loads. The cylindrical shank ensures secure clamping in standard toolholders and drill chucks, making the tool suitable for both hand drilling and machine use. This configuration supports safe, predictable machining when working with metals often encountered in production: steel, cast components and non‑ferrous materials, providing a single‑tool solution for a range of assemblies.

Measurable cutting performance for engineering certainty

Technical feed guidance is supplied for practical process planning: with a feed in steel up to 500 N, the recommended advance is 0.09 mm/rev, offering a balance between surface quality and tool life. The three cutting edges split the material removal load, which lowers vibration and improves surface texture. Engineers and planners gain measurable data to integrate the tool into existing cycles, enabling more reliable cycle time calculations and quality control.

Practical benefits for maintenance and efficiency

Using this countersink reduces the need for secondary finishing operations by delivering clean chamfers and reduced burr formation. The combination of HSS durability and the anti‑vibration flute geometry minimises premature wear, contributing to fewer tool changes and steadier throughput. For maintenance teams and workshop managers, this means lower process variability and a straightforward tool choice for routine hole preparation.
