ULTIMATECUT conical countersink DIN 335C, 90° Ø15 mm — RUKO (HSSE‑Co 5)

The ULTIMATECUT conical countersink is a precision tool for quiet, high‑quality deburring and chamfering in diverse production and workshop applications.

• Reduced axial and radial forces
• Very quiet, chatter‑free countersinking
• Wide flute for fast chip evacuation
• HSSE‑Co 5 for high wear resistance

Consistent high‑performance countersinking for stable processes

The redesigned cutting geometry significantly lowers the forces acting on the tool during the countersinking cycle; this results in reduced axial and radial forces and a much calmer machining process. The tool is produced to DIN 335C dimensions and the Ø15 mm nominal diameter ensures compatibility with standard holders and fixtures. The combination of an advanced helix profile and carefully shaped cutting edges produces an exact, round and chatter‑free sink finish, which reduces rework and improves assembly fit in serial production.

Less operator effort and resilient tool life through optimised chip control

A purposefully varied relief and an extra‑wide flute improve chip flow and heat removal, which in turn increases service life under continuous use. Specific chip clearance parameters — such as the rake angle and the transition radius — are optimised to prevent material welding on the cutting edge and to lower wear rates. For steel applications a recommended feed is 0.15 mm/rev at up to 800 N feed force; this provides a practical starting point for process setup and helps maintain consistent quality across cycles.

Versatile machining across different production tasks

The tool is engineered for dependable performance at both low and high cutting speeds without compromising the finish quality. Constructed from HSSE‑Co 5, the countersink demonstrates enhanced hot hardness and abrasion resistance, making it suitable for demanding workshop and industrial environments. The overall geometry supports stable handling during manual and machine operations, so both one‑off repairs and high‑volume manufacturing benefit from reduced vibration and predictable results.

FAQ

What materials can the ULTIMATECUT countersink handle?
The ULTIMATECUT countersink from RUKO is designed to perform across a wide range of materials; its HSSE‑Co 5 composition and flute geometry support stable results in many metallic and engineering polymer applications.

What feed and force parameters should be used for steel?
For steel applications a practical guideline is a feed of 0.15 mm per revolution at up to 800 N feed force; this reflects the tool’s design intent for reliable chip formation and consistent sink quality.

How does the ULTIMATECUT reduce chatter and achieve a smooth finish?
A variable relief geometry together with an extra‑wide flute and optimised transition radius minimise axial and radial loads, producing a chatter‑free surface and an exact, round countersink profile.

Is the tool suitable for automated production environments?
Yes. The countersink’s reduced cutting forces and improved chip evacuation make it well suited to machine mounting and serial production where process stability and tool life are priorities.
