Countersink EUC DIN 335 C 90° Ø10.4 mm – HSS special, 3‑flute cylindrical shank

The Countersink EUC DIN 335 C 90° Ø10.4 mm is a precision countersinking tool for clean, low‑force chamfering in steels, castings and non‑ferrous alloys

• HSS special coating for increased wear resistance
• EUC geometry reduces chatter and improves finish
• Cuts steel, cast iron and non‑ferrous metals
• 50% lower axial force, 25% less radial force

Precision design that reduces machine load and improves finish

This countersink combines a DIN 335 C profile with a 3‑flute HSS construction and a specialised coating to deliver consistent chamfering under industrial conditions. The EUC geometry (extremely unequal spacing) and radial relief grinding minimise harmonic excitation, which translates directly into less chatter and a finer surface at the hole edge. Lower axial and radial forces lead to reduced clamp and spindle stress, meaning fewer interruptions and longer intervals between tool changes. Recommended feed in steel is 0.1 mm/rev up to a cutting force of 500 N, offering a clear starting point for process setup.

Broad material capability with reproducible results

Engineered for the demands of workshop and production environments, this tool is suitable for steel, cast iron and non‑ferrous metals, enabling one countersink to cover multiple operations. The prepared cutting edges and right‑hand cutting geometry ensure reliable chip formation and predictable behaviour when deburring or creating chamfers. For manufacturers seeking to consolidate tooling and improve throughput, the tool’s precision execution reduces rework and supports tighter tolerances without complex parameter changes.

Practical handling and integration into existing processes

With a cylindrical shank compatible with standard holders and fixtures, this countersink integrates easily into automated and manual set‑ups. The precision manufacture and the optimised cutting geometry simplify tool alignment and reduce the necessity for high feed forces, which benefits small‑machine shops and heavy production alike. For any process questions or special machine conditions, Metav’s technical advisers can provide parameter guidance and selection support to ensure the best results from this specialised countersink.

FAQ

Is this countersink suitable for stainless steel and other hard alloys?
The EUC countersink is designed primarily for steel, cast iron and non‑ferrous metals; for specific stainless grades or hardened alloys, please consult Metav for confirmation on suitability.

What feed and force settings are recommended for reliable results?
A starting recommendation for the countersink in steel is 0.1 mm/rev at forces up to 500 N; Metav’s technical team can advise adjustments for differing materials and hole diameters.

Can the tool be used in standard collets and holders?
Yes, the cylindrical shank is compatible with standard tool holders and collets commonly used in workshop and production environments.

How does the EUC geometry benefit the machining process?
The extremely unequal flute spacing reduces harmonic excitation and chatter, improving surface finish and enhancing process stability compared with evenly spaced designs.
