Ruko Countersink Set DIN 335 C – HSS TiN, 90° (6.3–20.5 mm)

The Ruko Countersink Set DIN 335 C is a workshop-grade countersinking set designed for producing clean 90° chamfers and reliable screw seating across a wide diameter range

• Countersinks DIN 335 C, 3 cutting edges
• TiN coating for extended tool life
• Range 6.3–20.5 mm in sturdy plastic case

Consistent chamfers through engineered geometry

The set is built to the DIN 335 C standard and features a three‑cutting‑edge geometry that promotes balanced cutting forces and reduced vibration. Made from HSS (high‑speed steel) and enhanced with a TiN coating, the tools maintain cutting performance under frequent use and resist premature wear. For practical workshop applications this means clean, repeatable chamfers and fewer rejects when preparing screw seats or deburring bore edges, supporting reliable assembly quality in production and maintenance tasks.

Broad diameter coverage and secure storage

Covering a 6.3–20.5 mm diameter range, the set reduces tool changes for common countersinking sizes, improving workflow efficiency. Each insert sits in an impact‑ and break‑resistant plastic case, making tool selection quick and transport safe. The compact cassette keeps the components organised and protected from knocks, minimising downtime spent searching for the correct cutter and ensuring a tidy toolbench for day‑to‑day operations in both small workshops and larger maintenance departments.

Improved finishing and faster process cycles

The standard 90° countersink angle provides optimal contact for most flat and pan screw heads, promoting flush seating and a professional finish. The combination of the three‑edge geometry and TiN surface treatment results in smoother cutting and longer intervals between resharpening, which translates into reduced process interruptions and lower overall tool expenditure. For operators unfamiliar with technical specifications, the three‑flute design simply means steadier cutting and less chatter, producing consistent results across every workpiece.

FAQ

What materials are suitable for these countersinks?
The Ruko countersink set (countersink set DIN 335 C, SKU 4000601500NW) is made from HSS with a TiN coating and is intended for general metalworking countersinking tasks; suitability depends on the specific substrate and cutting parameters.

How does the TiN coating benefit workshop use?
TiN increases surface hardness and reduces friction, so the Ruko HSS tools keep sharper longer and provide better wear resistance during repetitive countersinking operations.

Are the cutters compatible with standard toolholders?
Yes, the cutters follow common geometric standards (DIN 335 C) and are compatible with typical handheld and machine mounting arrangements used for countersinking.

Does the set include storage for safe transport?
The set is supplied in an impact‑ and break‑resistant plastic cassette that secures each cutter and simplifies transport and storage.

What is the advantage of the three‑cutting‑edge design?
Three cutting edges balance cutting forces, reduce chatter and create smoother chamfers, which improves surface finish and repeatability in production and workshop tasks.
