TECWERK cone countersink DIN 335 C — 90° · 12.4 mm · HSS TiN · 3‑flute

TECWERK cone countersink DIN 335 C, 90° 12.4 mm HSS TiN, three‑flute design for countersinking and deburring

• HSS with TiN coating
• 90° tip to DIN 335 C
• Three‑flute design for chatter‑free cuts
• Cylindrical shank for secure clamping
• Suitable for steel, cast and non‑ferrous metals

Consistent, vibration‑reduced countersinking for accurate seating

The TECWERK countersink combines a three‑flute geometry with high‑speed steel and a thin TiN surface layer to deliver stable, chatter‑free performance when preparing bolt heads and chamfers. The 90° tip matches common fastener seating angles defined by DIN 335 C, ensuring exact fitment without secondary rework. The three cutting edges distribute cutting forces more evenly than a two‑flute tool, which reduces vibration and produces a cleaner edge; this is particularly helpful when repeatability and a precise seat are required in production or jobbing work.

Reliable cutting performance across common workshop materials

Engineered for use in a broad range of materials, the tool is effective on steel, cast iron and non‑ferrous metals. The specified feed performance — 0.14 mm per revolution at a cutting resistance up to 500 N in steel — indicates an efficient chip formation regime and predictable material removal. For less experienced users: the feed value is the linear advance per spindle revolution (chip load) and is a practical starting point for achieving a consistent finish without tool overload. The combination of substrate and coating extends useful life while maintaining cutting quality across different workpieces.

Firm clamping and straightforward handling for workshop workflows

A cylindrical shank provides compatibility with standard chucks and collets, allowing quick tool changes and secure clamping during countersinking and deburring operations. The geometry is optimised to minimise burr formation at the hole edge, which reduces manual finishing time and supports smoother assembly processes. Where exact alignment matters, the solid shank and balanced flute design help maintain concentricity and reduce run‑out, contributing to fewer rejects and shorter set‑up times.

Durable finish and economic machining for less downtime

The combination of HSS substrate and TiN coating offers a strong balance between toughness and wear resistance: the substrate absorbs impact loads while the coating reduces friction and improves heat resistance. This leads to longer intervals between tool changes and lower overall tooling costs per part in medium‑volume production. For operations looking to increase throughput without compromising hole quality, this countersink supplies a pragmatic route to efficiency gains and dependable performance.

FAQ

What materials is this countersink suitable for?
The TECWERK cone countersink (SKU 2000865195NW) is intended for use on steel, cast iron and non‑ferrous metals, offering reliable deburring and seating preparation across these materials.

What does the 0.14 mm/rev feed refer to?
The value 0.14 mm per revolution describes the recommended linear feed (chip load) in steel at cutting resistances up to 500 N for the TECWERK countersink; it is a practical starting point to balance finish and tool life.

How does the three‑flute design improve performance?
The three‑flute geometry of this countersink reduces vibration and distributes cutting forces, resulting in chatter‑free cuts and a cleaner hole edge compared with two‑flute alternatives.

Is the tip angle compatible with standard fasteners?
Yes, the 90° tip complies with DIN 335 C conventions and is suitable for preparing seats for common 90° head screws and countersunk fasteners.

Which shank types will accept this tool?
The countersink has a cylindrical shank, compatible with standard chucks and collets commonly found in workshop drill presses and machining centres.
