RUKO Countersink Set DIN 335 C — 90° HSS TiAlN

RUKO Countersink Set DIN 335 C is a precision countersinking kit designed for standardised chamfering and deburring tasks in workshop and industrial environments

• DIN 335 C standard design
• 90° precision cutting angle
• TiAlN coating for heat resistance
• Shock-resistant plastic cassette

Consistent cutting performance for predictable chamfers

The set combines HSS bodies with a TiAlN surface finish to increase wear resistance and thermal stability during intermittent and continuous cutting. The 3-flute configuration distributes cutting forces evenly, reducing vibration and promoting a uniform surface where the screw head seats. Together with the 90° geometry, this achieves repeatable chamfer dimensions that support assembly reliability and reduce rework.

Efficient workshop handling and protected transport

Tools are supplied in a robust plastic cassette that is shock- and break-resistant, keeping inserts organised and accessible. Clear layout speeds up tool selection and reduces downtime at the machine or workbench. The compact storage solution also protects the cutting edges during transport and storage, preserving durability and cutting performance across multiple jobs.

Industry-standard design for straightforward integration

Built to DIN 335 C, the countersinks match common engineering expectations for countersinking profiles, simplifying process planning and documentation. The set covers a practical diameter range so that a single kit addresses a variety of bore sizes and screw head recesses; the standardised form factor supports predictable machining results and easier quality control across batches.

FAQ

What sizes are included in the set?
The kit covers diameters from 6.3 mm to 20.5 mm, providing a range of countersink options for common bore sizes with the RUKO countersink set (SKU 4000601501NW).

What advantage does the TiAlN coating provide?
The TiAlN layer increases heat resistance and reduces wear on the cutting edge of the RUKO countersinks, extending tool life under demanding conditions.

Is the geometry compatible with standard fasteners?
Yes; the 90° cutting angle and DIN 335 C profile are designed to produce standardised chamfers that match common countersunk screw heads.

How does the 3-flute design affect performance?
The 3-flute geometry ensures balanced cutting forces and smoother material evacuation, which helps achieve a consistent finish and reduces vibration during countersinking.

How are the tools stored and transported?
The set is supplied in a shock- and break-resistant plastic cassette that protects the cutting edges and keeps sizes organised for quick selection.
