BECK Countersink EUC DIN 335 C – HSS special, 90° Ø 12.4 mm

BECK Countersink EUC DIN 335 C designed for precision chamfering and deburring in metalworking applications

• HSS special coating for extended tool life
• EUC unequal pitch for reduced chatter
• Reduces axial force by 50% for lower feed load
• 90° precision countersink with 3 flutes
• Suitable for steel, cast iron and non‑ferrous metals

Lower feed forces for steady production

The BECK countersink is manufactured in HSS with a special coating and a precision ground body that delivers measurable reductions in cutting forces. The optimised cutter geometry and prepared cutting edges result in an axial force reduction of around 50%, which translates into noticeably lower feed loads on drilling and countersinking heads. For production environments this means fewer tool changes and less stress on feeds and spindles, supporting steady cycle times and predictable process behaviour.

Smoother surfaces and reduced vibration

The tool’s EUC (extreme unequal crown) pitch and radial relief grinding are engineered to minimise chatter and radial excitation. The result is a 25% reduction in radial forces and a cleaner chamfer finish with reduced burr formation. These characteristics lead to improved component appearance and fewer secondary finishing steps, especially when working with mixed batches of castings and wrought parts where surface consistency matters.

Reliable machining across common workshop materials

Constructed to the DIN 335 C specification with 3 flutes and right‑hand cutting geometry, the countersink is suitable for machining steel, cast iron and non‑ferrous metals. The recommended feed in steel at cutting forces up to 500 N is 0.12 mm/rev, offering a reliable baseline for process planning. This numeric guidance simplifies integration into existing machining cycles and helps maintain dimensional control on chamfers and countersinks.

Durable geometry for repeatable chamfers

High manufacturing precision and the special coating extend tool life while maintaining dimensional stability of the chamfer. The combination of optimised cutting angles, prepared edges and radial relief ensures consistent countersink diameters and angles over longer tool life. In practice, this reduces rejects and rework while delivering the confidence required in batch and single‑part production alike.

FAQ

What materials is this countersink suitable for?
The BECK countersink is designed for use with steel, cast iron and non‑ferrous metals and is manufactured to deliver consistent chamfers across these materials.

How does the EUC design affect machining?
EUC (extreme unequal pitch) in the BECK countersink reduces rhythmic excitation and chatter, improving surface finish and cutting stability during countersinking.

What feed rate is recommended for steel?
A feed of 0.12 mm/rev is indicated for steel at cutting forces up to 500 N when using this BECK countersink.

Which standard does the tool conform to?
The countersink follows the DIN 335 C contour for 90° countersinks, ensuring compatibility with common engineering specifications for chamfer dimensions.
