TECWERK Countersink DIN 335 C Ø16.5 mm – HSS TiN, 90° 3‑flute

TECWERK Countersink DIN 335 C Ø16.5 mm is a precision chamfering tool for deburring and standard countersinking across a wide range of metals

• HSS with TiN coating for extended wear
• 90° chamfer angle for standard countersinks
• Three-flute design for rattle-free cutting

Precise chamfers from a DIN‑standard tool

The TECWERK countersink DIN 335 C Ø16.5 mm is manufactured to the DIN 335 C specification and combines a 90° chamfer angle with HSS substrate and TiN coating to deliver consistent, repeatable chamfers. The Ø16.5 mm geometry makes it suitable for creating standard countersinks and deburring bore edges, reducing the need for manual finishing. The TiN layer reduces friction and increases abrasion resistance, which results in longer tool life and fewer tool changes during production runs.

Smooth, vibration‑free cutting for clean edges

A three‑flute geometry provides balanced cutting forces and a rattle‑free cutting action, which improves surface quality at the chamfer and lowers the risk of chatter marks. The countersink features a cylindrical shank for secure clamping in standard toolholders and a predictable run-out. For machining in steel at cutting resistance up to 500 N, the recommended feed is 0.14 mm/rev, a value that supports efficient material removal without compromising edge quality. This combination of flute count and feed guidance enhances process reliability in both single‑item workshops and series production.

Versatile use across common workshop materials

Engineered for chamfering and deburring, the tool is suitable for steel, cast iron and non‑ferrous metals, making it a practical choice for maintenance, fabrication and production departments that handle mixed materials. The DIN‑compliant form and robust HSS body enable operation at conventional spindle speeds while the TiN coating helps resist built‑up edge on softer metals. The result is a reduction in rework and more consistent assemblies downstream, supporting leaner workflows and improved part quality.

FAQ

What materials can this countersink machine on?
The TECWERK countersink (DIN 335 C, Ø16.5 mm, SKU 2000865198NW) is suitable for steel, cast iron and non‑ferrous metals, as indicated by its HSS substrate and TiN coating.

How does the TiN coating affect performance?
The TiN coating on the TECWERK countersink improves wear resistance and reduces friction, which extends tool life and helps maintain chamfer quality during longer production runs.

Why is a three‑flute design advantageous?
A three‑flute geometry provides balanced cutting forces and a rattle‑free cut, resulting in cleaner chamfers and less vibration compared with two‑flute alternatives.

Which feed should be used for steel?
For steel under cutting resistance up to 500 N, the countersink achieves efficient results at around 0.14 mm/rev, as specified for the tool.

Is the shank compatible with standard toolholders?
Yes, the countersink has a cylindrical shank designed for secure clamping in standard collets and toolholders used in workshop and production environments.
