TECWERK Countersink DIN 335 C — 90° / Ø 6.3 mm / HSS, extra‑long

The TECWERK countersink for precise chamfers and deburring in steel, castings and non‑ferrous metals, designed with an extra‑long cylindrical shank for deep access

• HSS according to DIN 335 C
• 90° countersink angle for standard chamfers
• Extra‑long shank for deep bore access
• Three cutting edges for chatter‑free cutting

Consistent chamfers through industrial standard design

Built to DIN 335 C, this countersink delivers repeatable chamfers and clean deburring across series production. The use of HSS ensures a balance between toughness and sharpness, while the 90° geometry produces standard seat angles for fastener heads and assembly fits. The three‑edge geometry reduces vibration, so each operation results in a chatter‑free finish and fewer rejected parts — a direct benefit for throughput and first‑pass yield.

Deep‑reach capability for complex assemblies

The extra‑long cylindrical shank provides extended reach into plates, stepped bores and hard‑to‑access components without the need for extensions. Feed guidance for steel up to 500 N is given as 0.09 mm/rev, which allows the cutting action to remain stable and predictable; this parameter supports consistent surface quality and reduces the likelihood of tool marks. Integration into standard straight chucks and holders is straightforward thanks to the cylinder shank, enabling fast tool changes and minimal setup time.

Stable cutting behaviour across common materials

Designed for countersinking and deburring, the tool is suitable for steel, castings and non‑ferrous metals, making it a versatile choice for mixed‑material production environments. The three cutting edges distribute cutting forces evenly, improving chip formation and reducing radial loads on the workpiece. This stable behaviour lowers the need for post‑process finishing, saving time and reducing rework in the workshop.

FAQ

Which materials can this countersink be used on? The TECWERK countersink (SKU 2000865396NW) is suitable for steel, castings and non‑ferrous metals as specified; it is intended for both countersinking and deburring tasks.

What feed rate is recommended for steel? A feed of 0.09 mm per revolution is indicated for machining steel up to 500 N to maintain a stable cut and consistent surface quality.

Does the shank fit standard tool holders? The cylindrical shank is designed for compatibility with standard straight chucks and holders commonly used in drilling and milling setups.

How does the three‑edge geometry help the machining process? The three cutting edges distribute forces evenly and promote a more stable cut, resulting in a chatter‑free finish and reduced need for secondary deburring.

Is the tool suitable for deep or recessed holes? The extra‑long overall length enables access to deeper or recessed bores where a standard‑length countersink would not reach.
