Ruko Countersink Set DIN 335 C — 90° HSS with TiN coating

The Ruko countersink set DIN 335 C is a workshop-ready countersinking solution designed for precise chamfering and deburring with a standard 90° geometry, suitable for general metalworking applications.

• 90° countersink angle for standard chamfering
• High-speed steel with TiN coating
• Three cutting edges for consistent surface finish
• Shock- and break-resistant plastic case

Accurate chamfers with standard-compliant geometry

The set follows DIN 335 C and features a 90° countersink geometry with a three-edge cutting design, which delivers uniform chip formation and predictable chamfer profiles. The multi-edge configuration reduces vibration and spreads cutting forces across the blade faces, resulting in a cleaner edge and reduced need for manual rework. This standard compatibility aids integration into existing production processes and simplifies quality checks against recognised specifications.

Enhanced wear resistance and longer tool life

Each cutter is manufactured from high-speed steel (HSS) and finished with a titanium nitride (TiN) coating, which lowers friction at the cutting interface and increases surface hardness. The coating contributes to greater resistance against abrasive wear and heat, helping to extend tool life compared with untreated HSS in similar conditions. For operations that prioritise uptime and repeatability, the coated surface also minimises sticking and eases chip evacuation during light to medium countersinking tasks.

Practical storage and workshop efficiency

The set is supplied in a shock- and break-resistant plastic case that keeps inserts organised and protected during transport and storage, supporting quick tool selection at the bench. Clear arrangement and secure retention reduce downtime between operations and prevent damage that could compromise cutting geometry. By combining standardised tool geometry with durable packaging, the product supports a steady production flow and straightforward inventory handling within small workshops and maintenance departments.

FAQ

What standard does the set comply with? The set is manufactured to DIN 335 C, featuring a 90° countersink geometry as stated on the product label and listing (SKU 4000601500NW).

What cutting material and coating are used? The cutters are made from high-speed steel (HSS) and finished with a TiN coating, which improves wear resistance and reduces friction during countersinking operations.

Which sizes and angles are included in the set? The set covers a size range of 6.3–20.5 mm and uses a 90° countersink angle, arranged in a compact, protective plastic case.

How does the three-edge design affect performance? The three cutting edges distribute cutting forces and produce a more consistent chip flow and surface finish, reducing vibration compared with single-edge countersinks.

Is the tool case suitable for workshop use? Yes, the shock- and break-resistant plastic case secures the cutters for transport and storage, helping to protect cutting geometry and simplify tool selection.
