6.3mm Countersink 90° HSS 3-Flute Special Coating, Right-Hand, Precision Ground - MAPAL Dr. Kress SE & Co. KG

Combine the high-performance HSS construction with an EUC-optimised geometry to achieve smoother chamfers, significantly reduced axial and radial forces, and longer tool life; order the countersink directly via Metav Werkzeuge or ask our consultants if needed.

BECK Countersink EUC DIN 335 C — 90° Ø6.3 mm, HSS, 3-flute

The BECK Countersink EUC DIN 335 C is a precision 90° countersinking tool designed for clean chamfers in steel, cast iron and non‑ferrous metals in industrial workshop and production environments.

• HSS special coating for increased tool life
• 90° precision countersink for standard chamfers
• Radially relieved, precision-ground flutes
• Suitable for steel, cast iron and non‑ferrous metals

Lower feed forces for steady production flow

This countersink combines a high-speed steel (HSS) substrate with a special coating and an optimised flute geometry to reduce machining forces. The axial force is reduced by about 50%, which lowers the required feed effort and reduces motor load on drilling heads and machines. As a result, process stability increases and cycle times become more predictable. The specification also notes a feed recommendation in steel up to 500 N of 0.08 mm/rev, providing a reliable baseline for production programming.

Smoother surface finish thanks to EUC geometry

The tool’s EUC (extremely unequal spacing) and three-flute arrangement minimise vibration and tendency to chatter by breaking up harmonic excitation. The cutting edges are precision-ground and radially relieved, while the prepared cutting edges ensure consistent material flow during chamfering. This geometry leads to a cleaner chamfer edge and reduced burr formation, which decreases the need for secondary deburring operations and thus saves assembly time further down the line.

Versatile application and process benefits

Designed as a right‑hand cutting countersink to DIN 335 C standards, the tool is suitable for a broad range of materials: steel, cast iron and non‑ferrous metals. The combination of precision execution and the special coating extends tool life under repetitive use and supports higher cutting speeds where applicable. For series production the reduced radial force (approximately 25% lower) contributes to improved hole concentricity and less deflection on slender workpieces, improving overall part quality and reducing rejects.

FAQ

What materials can this countersink process reliably?
The BECK Countersink EUC DIN 335 C is specified for steel, cast iron and non‑ferrous metals, making it suitable for a wide range of workshop and production tasks.

How does the EUC design affect machining quality?
EUC (extremely unequal spacing) breaks up harmonics and reduces vibration; this improves surface finish and reduces chatter when using the BECK countersink.

What feed should be used as a starting point in steel?
A practical guideline for the tool is 0.08 mm/rev in steel for cutting forces up to 500 N; adjust feeds for machine rigidity and material condition when required.

Is the countersink suitable for series production?
Yes, the precision design, special coating and reduced axial/radial forces make the tool well suited for repetitive production and automated cells.

Does the tool require special machine interfaces?
The countersink is a standard 3‑flute design for conventional toolholders and drilling setups; ensure correct clamping and alignment to benefit from the reduced forces.
