BECK Countersink set – HSS, 90° DIN 335 C, EUC, 6.3–25 mm

The BECK countersink set for workshop and production use, designed for clean 90° chamfers and deburring on steel, cast and non‑ferrous metals

• HSS special coating for extended life
• EUC geometry for vibration‑reduced cutting
• Precision radial relief for smooth finish
• Supplied in a robust plastic case

Precision geometry that cuts down force and chatter

The set is engineered with an EUC (extremely unequal division) and a three‑cutting‑edge layout to distribute cutting forces unevenly and break harmonics. This design leads to a 50% reduction in axial force and 25% lower radial force, which in practice means less required feed pressure and noticeably reduced tendency to chatter on thin or flexible workpieces. The result is more consistent chamfers and fewer rejects in serial production.

Hardened HSS and special coating for durable performance

Manufactured from HSS and finished with a special coating, the tools combine wear resistance with cutting edge integrity. The coating supports higher cutting temperatures and helps maintain geometry over repeated cycles, while the radial back‑grind and prepared cutting edges improve chip formation and surface finish. For small toolrooms and industrial users alike, this translates into longer tool life and fewer tool changes per shift.

Versatile application across common workshop materials

The set was developed to handle steel, cast iron and non‑ferrous metals, making it a flexible choice for mixed jobs. The 90° countersink angle complies with DIN 335 C standards, ensuring standard chamfer profiles for screw seating and deburring. A cylindrical shank and right‑hand cutting orientation simplify mounting and integration into standard toolholders and drill presses, giving predictable results in diverse machining setups.

Neat storage and workshop organisation

Supplied as a five‑piece set in a labelled plastic box, the kit reduces downtime through clear organisation and secure transport. The compact case protects the precision edges and makes it easy to identify sizes at the workbench. For maintenance teams and production engineers, the straightforward labelling and robust packaging aid inventory control and minimise accidental damage.

FAQ

What materials can be processed with this countersink set?
The BECK countersink set is suitable for processing steel, cast iron and non‑ferrous metals as specified in the technical description.

How does the EUC geometry affect machining quality?
EUC geometry in the set reduces harmonic vibrations and spreads cutting forces, which improves surface finish and reduces chatter during countersinking.

Are these countersinks compatible with standard drill chucks and holders?
Yes; the cylindrical shank and right‑hand cutting orientation ensure compatibility with typical drill chucks and toolholders.

What packaging is supplied with the set?
The set is supplied as a five‑piece kit in a labelled plastic box for organised storage and transport.

Which standard does the countersink angle conform to?
The countersink angle conforms to DIN 335 C, providing a standard 90° chamfer suitable for common screw seating and deburring tasks.
