31mm Countersink 90° Three-Point HSS-Co 3-Flute Cylindrical Shank, For Steel Cast Non-Ferrous Metals - TECWERK

High-strength HSS‑Co alloy combined with a three‑flute, 90° geometry delivers reliable, chatter‑free countersinking and fast deburring across steel and non‑ferrous materials. Order the TECWERK countersink directly via Metav Werkzeuge or ask Metav Werkzeuge consultants if needed.

TECWERK countersink DIN 335 C — 90° conical countersink, 31 mm, HSS‑Co, 3‑flute

A TECWERK countersink DIN 335 C, 90° designed for precise countersinking and burr removal in steel, cast iron and non‑ferrous metals, with a cylindrical shank for standard tool holders

• DIN 335 C standard geometry
• 90° countersink angle for precise seating
• Three-flute design for chatter-free cutting
• HSS-Co for stainless and heat-resistant steel

Consistent hole finishing with reduced vibration

The conical 90° cutting geometry specified to DIN 335 C ensures a uniform seat for fasteners and clean chamfers. The three‑flute design produces a chatter‑free cut, which reduces rework and improves surface quality compared with two‑edge variants. This results in more consistent assembly fits and fewer rejects when machining components from steel, cast iron or aluminium alloys.

Robust alloy and construction for demanding materials

Manufactured in HSS‑Co, the tool is formulated for elevated thermal stability and wear resistance, making it suitable for stainless and heat‑resistant steels in addition to conventional steel grades. The cylindrical shank is intended for secure mounting in common tool holders, so the tool life is extended and changeover is straightforward. The combination of durable material and standardised geometry supports repeatable performance in industrial workshop environments.

Productivity through geometry and recommended feed data

The three cutting edges, which provide a rattle‑free engagement, enable smooth material evacuation and reduced cutting forces during countersinking. A feed of 0.22 mm per revolution is specified for steel under cutting forces up to 500 N, offering a practical baseline to balance surface finish and cycle time. The result is faster processing of batches with fewer interruptions for tool maintenance, contributing to steady throughput on production benches.
