Countersink DIN 335 C 90° Ø10.4 mm HSS TiN, 3 flutes – TECWERK

Countersink DIN 335 C 90° Ø10.4 mm HSS TiN, 3 flutes – TECWERK is a precision conical countersink designed for accurate hole finishing and deburring across a wide range of metallic materials

*High-speed steel with TiN coating
*90° conical geometry for precise countersinking
*Three-flute design for chatter-free cutting
*Cylindrical shank for secure toolholding

Precision finishing for consistent assembly results

The TECWERK countersink follows the DIN 335 C specification and combines a conical 90° profile with a Ø10.4 mm cutting diameter to create uniform chamfers and clean deburred edges. The use of HSS as the base material, enhanced with a TiN coating, reduces wear and improves surface finish, which helps maintain repeatable assembly tolerances. This consistency reduces rework and supports streamlined production processes.

Smooth, chatter-free cutting increases productivity

A three‑flute geometry delivers a balanced cut that significantly reduces vibration and chatter compared with two‑flute designs. The result is a chatter‑free countersinking action that leaves a controlled edge and minimises the need for secondary finishing. For machining tasks in steel, the recommended feed up to 0.12 mm/rev at forces up to 500 N helps preserve tool life while maintaining effective material removal rates.

Versatile compatibility across common workshop materials

Engineered for both countersinking and deburring, the tool is suitable for steel, cast iron and non‑ferrous metals, making it a flexible option for mixed‑material production environments. The TiN surface hardening improves resistance to abrasion and reduces built‑up edge on softer alloys, enabling reliable performance when switching between different workpiece materials without frequent tool changes.

Secure clamping and simple integration into existing tooling

A cylindrical shank ensures stable mounting in standard toolholders and collets, providing secure toolholding during operation. The compact, standardised design supports easy integration into workshop routines and minimises setup time. Low maintenance requirements, coupled with robust material and coating choices, contribute to lower total cost of ownership over the tool’s service life.

FAQ

Is this countersink suitable for stainless steel?
The TECWERK countersink is primarily specified for steel, cast iron and non‑ferrous metals; stainless steel may be machined depending on grade and cutting parameters, but tool selection should consider workpiece hardness and cutting speed.

What advantage does the TiN coating provide?
The TiN coating on this countersink improves surface hardness and wear resistance, which enhances tool life and reduces adhesion on softer alloys during countersinking and deburring.

How does the three‑flute design affect the finish?
The three‑flute geometry produces a more balanced cut compared with two flutes, resulting in chatter‑free operation and a cleaner chamfer with less need for secondary finishing.

What clamping systems are compatible with the shank?
The cylindrical shank is compatible with standard collets and toolholders, providing secure toolholding for typical workshop and production setups.

Can this tool be used for both countersinking and deburring in one pass?
Yes, the conical 90° profile and the balanced flute design enable combined countersinking and deburring in many applications, reducing cycle time where geometry and material allow
