RUKO annular cutter D12 mm — HSS with TiAlN, 30 mm cutting depth

The RUKO annular cutter D12 mm is a robust core drill for professional metalworking, designed for precise through‑holes in steel and non‑ferrous materials.

• High-performance HSS construction
• TiAlN coating for dry machining
• Secure Weldon shank 19.05 mm
• 30 mm cutting depth for deeper holes

Faster, more consistent holemaking with hardened HSS construction

The annular cutter’s HSS construction and compact geometry ensure consistent hole diameter and a clean bore surface, reducing the need for secondary finishing. With a 12 mm cutting diameter and 30 mm cutting depth built into a 63 mm overall length, the tool shortens cycle times while maintaining dimensional accuracy. The combination of four cutting edges and a stable tool body supports smooth chip formation and repeatable results in production environments.

TiAlN wear protection increases uptime and enables dry processes

The TiAlN wear protection raises surface hardness to around 3,000 HV and preserves hot hardness up to 900°C, providing improved resistance to thermal and chemical wear. This thermal stability translates into longer tool life and higher permitted cutting values under intermittent heat loads. The coating is formulated for dry machining, allowing reduced coolant use and simplified process logistics while maintaining tool performance.

Wide material capability for versatile workshop use

Engineered for demanding materials, the cutter performs well on unalloyed and alloyed steels up to 1,200 N/mm², as well as high‑chromium stainless grades such as V2A and V4A, steel castings and tougher brass alloys. This breadth of compatibility means fewer tool changes across diverse jobs, increasing operational flexibility and lowering tooling inventory needs in small workshops and industrial settings alike.

Solid clamping and practical handling for reliable setups

A Weldon shank with a diameter of 19.05 mm (3/4") provides secure axial and torsional fixation in standard holders, reducing slippage and run‑out during drilling. The fixed‑shank design supports rapid tool changes and stable machining under load. Supplied as a single unit, the cutter is ready for immediate integration into standard Weldon holders and magnetic or portable drilling set‑ups, helping to keep production moving with predictable quality.

FAQ

What materials can this annular cutter machine?
The RUKO annular cutter is designed for unalloyed and alloyed steels up to 1,200 N/mm², high‑chromium stainless grades such as V2A and V4A, steel castings and tougher brass alloys.

Is the TiAlN coating suitable for dry drilling operations?
Yes, the TiAlN coating on the RUKO cutter is formulated to withstand elevated temperatures and is suitable for dry machining, reducing or eliminating the need for coolant in many applications.

Which shank sizes and holders are compatible with this cutter?
The cutter features a Weldon shank of 19.05 mm (3/4"), compatible with standard Weldon holders and fixtures that accept 3/4" Weldon‑style clamping systems.

How does the cutter’s geometry affect chip evacuation and finish?
The tool’s four cutting edges and annular design promote efficient chip formation and evacuation, producing a cleaner bore with reduced burrs and a more consistent surface finish compared with solid drills.
