Ruko HSS Annular Cutter D 23 mm – 30 mm Cutting Depth, Weldon Shank

A Ruko HSS annular cutter designed for efficient through-hole production in steel, cast components and non-ferrous metals with a secure Weldon shank for stable clamping

• High-performance HSS construction
• 23 mm diameter for precise core drilling
• 30 mm cutting depth for thicker materials
• Weldon 19.05 mm (3/4") shank for secure clamping

Faster, cleaner holes with periphery cutting

This annular cutter is manufactured from HSS, offering a balance of toughness and wear resistance for industrial drilling tasks. By removing only the material at the hole periphery rather than the full core, the tool achieves faster cycle times and reduced power draw compared with conventional twist drills. The cutter’s 6 cutting edges ensure effective engagement and improved chip formation, which reduces spalling and yields a cleaner bore. For production environments this translates into increased throughput and more consistent hole quality.

Stable clamping for accurate results

A Weldon 19.05 mm (3/4") shank provides positive, lateral fixation in Weldon-style holders and magnetic drill arbors, reducing runout and vibration during machining. The overall length 63 mm gives adequate reach for many common setups while the robust shank geometry improves concentricity. Together, these characteristics enhance positional accuracy and extend the effective life of the tool, making the cutter suitable for repetitive operations where alignment and repeatability are essential.

Versatile material compatibility for workshop use

Designed for work on a variety of metals, the cutter is suitable for steel (including structural profiles and large sheets), cast steel, and non-ferrous and light metals. The specified 30 mm cutting depth enables one-pass holes in medium-thickness components, reducing secondary operations. The high-speed steel composition remains the pragmatic choice for many fabrication and maintenance tasks where toughness and reliable edge retention are required without the need for specialised coatings.

Practical care and handling to preserve performance

To maintain cutting performance, apply an appropriate cutting fluid when machining steels and secure the workpiece firmly to avoid movement. Regular inspection of the tool nose and flutes helps detect wear early; reconditioning by a qualified service extends service life where economical. The cutter’s peripheral cutting principle minimises heat build-up in the centre of the hole, which helps preserve dimensional stability and reduces the frequency of tool changeovers in demanding production runs.
