Kegelsenker DIN 335C 90° D4.3 HSS TiN, 3‑flute countersink (TECWERK)

The Kegelsenker DIN 335C 90° D4.3 HSS TiN Z.3 TECWERK is a three‑flute, 90° conical countersink designed for clean chamfers and burr removal in steel, castings and non‑ferrous metals, with a cylindrical shank for reliable clamping.

• Countersink 90° for standard chamfers
• HSS substrate with TiN coating
• Three‑flute geometry for chatter‑free cuts
• Cylindrical shank for secure clamping

Precise chamfers and reliable deburring for workshop production

The three‑flute countersink follows the DIN 335 C specification to deliver consistent 90° chamfers and radial symmetry in hole finishing. The three cutting edges ensure a rattle‑free cutting action, which reduces vibration and delivers a clean burr‑free edge on through and blind holes. For production environments where repeatability matters, this conical tool provides predictable results across mild steel, cast iron and a range of non‑ferrous metals, helping to maintain component tolerances and minimise rework.

Longer tool life through hardened substrate and surface coating

This chamfering tool is manufactured from high‑speed steel (HSS) and finished with a TiN (titanium nitride) coating to increase surface hardness and reduce built‑up edge. The coating improves wear resistance under intermittent cutting and extends the interval between tool changes. In practice, the combination of HSS and TiN supports robust performance on mixed batches and small series production, offering a balance between toughness and abrasion resistance without the need for special tooling systems.

Controlled feed and application guidance for consistent results

The tool is optimised for controlled feeds; in steel under a cutting force up to 500 N a recommended feed of approximately 0.07 mm/rev provides an efficient material removal rate while preserving edge quality. The cylindrical shank suits standard collet and chuck holders, ensuring concentric clamping and minimal runout. Typical tasks include deburring drilled holes prior to assembly, creating standard 90° chamfers for countersunk screws, and removing flash on cast components. For quieter cutting and improved surface finish, match speeds and feeds to workpiece material and machine rigidity.

FAQ

What materials can this countersink process effectively?
The Kegelsenker (TECWERK three‑flute countersink) is suitable for steel, castings and non‑ferrous metals and is optimised for general chamfering and deburring tasks.

How does the TiN coating benefit tool life?
The TiN coating on the TECWERK HSS countersink increases surface hardness and reduces wear, extending tool life under typical workshop conditions.

Is the shank compatible with standard collets?
Yes, the cylindrical shank is intended for secure clamping in standard collets and chucks to maintain concentricity during chamfering.

What feed should be used for steel components?
For steel under a cutting force up to 500 N, a recommended feed is around 0.07 mm per revolution for the specified countersink geometry.

Does the tool conform to recognised standards?
The countersink follows the DIN 335 C specification and is designed for 90° chamfering applications
