TECWERK 90° conical countersink, 8 mm — HSS, 3‑flute, DIN 335 C

A TECWERK 90° conical countersink designed for reliable chamfering and deburring of drilled holes in steel, cast iron and non‑ferrous metals, compatible with standard cylindrical shank toolholders

• HSS material, DIN 335 C specification
• 90° chamfer angle for standard countersinking
• Three‑flute geometry for chatter‑free cutting
• Cylindrical shank for secure toolholding

Fast, consistent chamfering that reduces rework

The tool is made from HSS, optimised for repeatable performance in mixed workshop and production environments. The 90° cutting angle matches common chamfer standards, while the three‑flute geometry produces a chatter‑free cut that minimises burr formation and the need for secondary finishing. With a rated feed 0.09 mm/rev in steel at up to 500 N, the cutter balances efficient material removal and surface integrity for repeatable hole preparation.

Seamless fit into existing tooling systems

Compliant with DIN 335 C, the countersink integrates easily into standard toolholders thanks to its cylindrical shank, enabling quick changeovers and stable clamping. This compatibility reduces set‑up time and supports predictable cycle planning on both manual machines and CNC centres, delivering consistent results across batches without special adapters or modifications.

Built for steady production and longer uptime

The three‑edge design distributes cutting forces evenly, lowering vibration and extending edge life compared with two‑edge alternatives. The result is smoother surfaces and fewer rejected parts, which improves overall yield and reduces downstream costs. The robust HSS substrate provides a dependable combination of toughness and wear resistance for typical workshop applications and serial production tasks.

Practical guidance for reliable application

For best results secure the workpiece firmly and use appropriate light cutting fluid when working harder alloys; softer non‑ferrous metals often permit dry operation. The cutter is intended primarily for deburring and countersinking operations on steel, cast iron and non‑ferrous metals; adherence to the specified feed parameters helps maintain cutting quality and tool life. If uncertain about feeds or clamping, consult the product data or our technical advisers.

FAQ

What materials can this countersink process?
The countersink is suitable for steel, cast iron and non‑ferrous metals; the HSS construction handles common workshop alloys effectively.

Is the 8 mm size the cutting diameter or the shank diameter?
The 8 mm designation refers to the cutting diameter of the conical countersink.

What does DIN 335 C indicate for this tool?
DIN 335 C denotes the standardised conical countersink form and geometry, ensuring dimensional and functional compatibility with industry tooling expectations.

How does the three‑flute design affect finish quality?
Three cutting edges distribute forces and reduce vibration, resulting in a chatter‑free cut and improved surface finish compared with fewer‑flute alternatives.
