RUKO Annular Cutter D14 HSS TiAlN – 30 mm cutting depth, Weldon shank

The RUKO Annular Cutter D14 HSS TiAlN is a 14 mm high-speed steel annular cutter with a TiAlN wear-protection coating, engineered for efficient holemaking in alloyed and stainless steels as well as tough brass.

• TiAlN coating for extended tool life
• 14 mm diameter, 30 mm cutting depth
• Weldon shank 19.05 mm (3/4") for secure clamping
• Suitable for alloyed and stainless steels

Increased productivity through thermal-stable cutting

The RUKO annular cutter D14 combines a TiAlN coating with a high-speed steel substrate to deliver improved wear resistance and thermal stability. The coating raises surface hardness to about 3,000 HV and preserves hardness at elevated temperatures up to 900°C, enabling longer intervals between regrinds and fewer tool changes. As a result, batch holemaking becomes more economical and predictable, particularly where cycle time and tool-change minimisation are key performance indicators.

Reliable machining across demanding materials

Designed for industrial applications, the cutter is suitable for unalloyed and alloyed steels up to 1,200 N/mm², high-chromium grades such as V2A and V4A, steel castings and resilient brass. The combination of four cutting edges and the TiAlN surface treatment supports consistent chip formation and stable cutting parameters. For procurement managers and production engineers, this means fewer rejects and a higher first-pass yield when processing mixed batches of ferrous materials.

Secure clamping and straightforward handling at the machine

A Weldon shank (19.05 mm / 3/4") provides positive axial locking in compatible holders, reducing the risk of slippage during heavy cuts. With a 30 mm effective cutting depth and 63 mm overall length, the tool offers a practical balance between reach and rigidity. The design is optimised for routine use in slotting and holemaking stations on horizontal and vertical drilling machines, and in CNC setups where clamping repeatability contributes directly to process stability.

Practical operating advantages and maintenance note

The TiAlN coating makes the cutter well suited to dry machining, reducing coolant costs and simplifying chip evacuation in many production setups. The tool’s increased warm hardness and chemical stability contribute to longer tool life under interrupted cuts and elevated temperatures. For maintenance planning, tracking tool life by hole count or operating time allows predictable regrind scheduling and supports spare-part stocking strategies for uninterrupted production.
