Annular cutter Ø22 mm HSS — 30 mm cutting depth, Weldon shank (RUKO)

An annular cutter Ø22 mm HSS designed for fast, accurate through-hole cutting in steel, castings and non‑ferrous metals.

*HSS construction for durability and heat resistance *30 mm cutting depth for through‑hole applications *Weldon shank 19.05 mm (3/4") for secure clamping *Suitable for steel, cast iron and non‑ferrous metals

Deliver consistent, high‑speed holemaking for production use

The annular cutter is engineered to remove material efficiently from the periphery of a hole rather than drilling the full core, which reduces cycle time and the power required from the machine. Made from HSS, the tool sustains elevated cutting temperatures and maintains edge strength under continuous operation, resulting in fewer tool changes and improved throughput. With a 22 mm diameter and a 30 mm cutting depth, the cutter is particularly suited to common structural and fabrication tasks where fast, accurate holes are required in medium‑thickness sections.

Secure fixturing and toolholding for repeatable accuracy

A decisive benefit is the Weldon shank, sized at 19.05 mm (3/4"), which provides positive engagement in standard Weldon clamping systems and guarantees secure clamping during heavy cuts or intermittent feeds. The six cutting edges promote stable chip formation and reduced vibration, supporting repeatable hole quality and longer life between regrinds. For workshop planners, this translates into predictable cycle times and stable tolerances when working with structural steel, castings or light alloys.

Practical guidance for shops and fabricators

The annular cutter is compatible with a range of metalworking applications: drilling in structural steel, steel castings and non‑ferrous or light metals benefits from the HSS substrate and multi‑edge geometry. Use appropriate cutting fluid for steels to extend life and improve surface finish; for non‑ferrous metals, moderate feed and chip evacuation avoid built‑up edge. The cutter’s design reduces waste compared with twist drilling and facilitates easier material handling of the core.

Operational advantages and maintenance suggestions

By focusing material removal on the annulus, the cutter lowers energy draw and reduces heat generation in the workpiece, which can protect heat‑sensitive assemblies and reduce post‑machining distortion. Periodic inspection of the cutting lips for wear and timely regrinding of the multi‑edge profile restore performance without full replacement. Choosing tools from a trusted supplier reduces procurement complexity and supports uninterrupted production when spare‑part stock is required.

FAQ

Which materials is this cutter suitable for? The RUKO annular cutter Ø22 mm HSS (SKU 4000602301NW) is suitable for steel, steel castings and non‑ferrous or light metals, as indicated in the technical description.

What does the Weldon shank mean for toolholding? A Weldon shank (19.05 mm / 3/4") enables positive, anti‑rotation clamping in standard Weldon toolholders, ensuring the cutter remains firmly secured during the cutting process.

Can the cutter be re‑sharpened? Yes, the multi‑edge HSS geometry can be regrinded by a qualified sharpener to restore cutting edges and extend service life, maintaining the original cutting profile where possible.

Is cutting fluid recommended? Use appropriate cutting fluid for steel to improve tool life and surface finish; for aluminium and softer non‑ferrous metals, reduced coolant and careful chip evacuation are advised to avoid built‑up edge.

What are the main advantages over standard twist drills? The annular cutter removes the material only from the hole perimeter, which reduces cutting energy, speeds cycle times and produces cleaner cores; this makes it more efficient for larger‑diameter or repeat holemaking tasks.
