TECWERK 90° Countersink Ø6.3 mm — HSS‑Co, TiAlN, 3‑flute

TECWERK 90° Countersink Ø6.3 mm for precise, low‑vibration chamfering and countersinking across a wide range of materials

• HSS‑Co with TiAlN coating
• 90° conical geometry for precise countersinking
• Spiral‑fluted with three convex cutting edges
• Reduced feed and radial forces for smooth cuts

Engineered for efficient, chatter‑free countersinking

The TECWERK conical cutter is designed to deliver round, exact and chatter‑free countersinking, thanks to its spiral‑fluted geometry and three unequal convex cutting edges. The combination of HSS‑Co substrate and TiAlN coating reduces friction and heat build‑up, enabling stable machining and longer tool life. Measurable reductions in machining load translate into more reliable cycles and fewer rejects under high‑precision conditions.

Wide material compatibility for workshop and production use

This 90° conical cutter performs across a broad spectrum of materials: steel, stainless and heat‑resistant steels, aluminium, brass and various plastics. The tool’s geometry and coating minimise burr formation and improve surface finish, which benefits both manual set‑ups and automated processes. Where a single countersink is required to cover several tasks, the tool’s versatility reduces tool changes and simplifies tooling logistics.

Long service life and measurable process benefits

Spiralised cutting edges and the cobalt‑enhanced high‑speed steel construction contribute to extremely high stand times, lowering total machining cost per part. The tool achieves up to 60% lower feed force and 50% lower radial force, which reduces spindle and fixture load and supports more consistent cycle times. Recommended feed in steel up to 800 N is 0.095 mm/rev, offering a clear baseline for process planning and optimisation.

Simple integration into standard machining set‑ups

Conforming to DIN 335 C and supplied with a cylindrical shank in Form C, the countersink is suitable for collet chucks and standard tool holders; it is right‑hand cutting and compatible with conventional machining and CNC centres. The compact Ø6.3 mm diameter and standard geometry make it straightforward to replace existing tools while improving performance, making this cutter a practical choice for production shops and precision workshops alike.

FAQ

What materials can this countersink machine?
The TECWERK 90° countersink Ø6.3 mm (SKU 2000865290NW) is specified for steel, stainless and heat‑resistant steels, aluminium, brass and various plastics.

How does the TiAlN coating benefit performance?
The TiAlN coating on the HSS‑Co body reduces friction and thermal load, increasing the service life of the TECWERK countersink and improving surface finish during high‑duty countersinking.

What feed rate should be used for steel operations?
For steel up to 800 N, a feed of approximately 0.095 mm/rev is recommended for the TECWERK 90° countersink to balance cutting engagement and tool life.

Is the tool suitable for CNC use and manual drilling?
Yes; the countersink’s cylindrical shank and DIN 335 C Form C geometry allow straightforward clamping in collets and chucks for both CNC centres and manual set‑ups.

Can this countersink reduce chatter and improve finish?
The spiral‑fluted, three‑edge geometry together with the HSS‑Co substrate and TiAlN coating provides round, exact and chatter‑free countersinking, enhancing finish quality.
