6.3mm Countersink 75° HSS 3-Flute Shank 5mm, Right-Hand - TECWERK

Take advantage of a precise 75° countersink angle combined with HSS construction and a 5 mm cylindrical shank for reliable, burr-free chamfering and countersinking. The tool’s three-flute geometry and right-hand cutting action deliver smooth results at low cutting speeds, ensuring consistent assembly fit and reduced rework; order via Metav Werkzeuge or consult Metav’s specialists for application guidance.

TECWERK 75° Countersink 6.3 mm — HSS, 3-flute, Ø 5 mm shank

The TECWERK 75° Countersink 6.3 mm is a high-speed steel chamfer cutter designed for burr-free countersinking, deburring and light chamfering in steel, castings and non-ferrous metals

• HSS construction, Form C, 3 flutes
• 75° countersink angle for precise chamfers
• Cylindrical shank Ø 5 mm for secure clamping
• Optimised for burr-free deburring and countersinking

Clean chamfers for dependable assemblies

The combination of a 75° countersink angle and HSS material provides a consistent conical seat for countersunk fasteners and creates a neat chamfer that reduces assembly tolerance issues. The tool’s three-flute geometry helps to distribute cutting forces more evenly than two-flute variants, which results in a burr-free finish and less manual deburring. Where component fit and surface quality matter, this countersink reduces downstream labour and improves first-pass yield on production runs.

Efficient machining at conservative speeds

Designed for stability rather than high-speed removal, the cutter achieves the best surface quality at low cutting speeds; recommended feed in steel up to 500 N: 0.09 mm/rev. The right-hand cutting orientation and Form C geometry contribute to controlled chip formation and reduced chatter, which is especially important when working with mixed assemblies or thin-walled parts. This focus on efficient, repeatable cutting makes the tool a practical choice for both workshop tasks and small-scale production.

Secure clamping and broad material suitability

A cylindrical shank Ø 5 mm simplifies clamping in common drill chucks and collet systems, enabling quick tool changes and consistent concentricity. The cutter is suitable for steel, cast parts, brass and light metals, delivering good results on deburring and countersinking applications across these materials. Its solid HSS body offers a balance of toughness and edge retention for general workshop use, providing a cost-effective option for shops that prioritise reliability and predictable tool life.

FAQ

What materials is this countersink suitable for?
The TECWERK 75° Countersink is suitable for steel, castings, brass and light non-ferrous metals and delivers burr-free countersinking in these materials.

What shank size is required for clamping this tool?
This countersink features a cylindrical shank of 5 mm and is designed for secure clamping in standard chucks and collets.

What cutting data should be used in steel?
For steel, the tool’s guidance indicates a feed of 0.09 mm per revolution at conservative cutting speeds for optimal surface quality.

How does the three-flute design affect performance?
The three-flute geometry of the countersink improves load distribution and chip control, resulting in smoother finishes and reduced burr formation compared with two-flute designs.
