RUKO Annular Cutter D26 mm HSS — 30 mm cutting depth, Weldon shank

A RUKO annular cutter D26 mm HSS designed for efficient, burr‑reduced through‑holes in structural steel, cast iron and light non‑ferrous alloys

• High-performance HSS construction
• Weldon shank 19.05 mm (3/4") for secure clamping
• 26 mm diameter for precise core holes
• 30 mm cutting depth for efficient material removal

Better cuts with high‑alloy HSS and multiple cutting edges

Constructed from HSS, this annular cutter uses multiple cutting teeth to remove a ring of material rather than the full core, which reduces the required drilling force and delivers cleaner holes with less burr. The multi‑edge design with seven cutting edges increases chip evacuation and extends tool life under interrupted cuts typical of structural work. For workshops seeking predictable cycle times, the steel‑grade substrate and tooth geometry provide steady performance when cutting through T‑sections, heavy plates and similar workpieces.

Secure clamping for rapid hole production

The Weldon shank 19.05 mm (3/4") offers a robust interface for magnetic drills and arbor systems, reducing slippage during high‑torque operations and enabling repeatable hole placement. With a 30 mm cutting depth, the cutter completes a single pass for many common through‑hole applications, cutting time and reducing the need for pilot drills. The annular principle leaves a solid slug that is easily removed, lowering the load on the drill unit and improving energy efficiency in production settings.

Clear benefits for everyday workshop use

Suitable for steel, cast iron and a range of non‑ferrous and light metals, this tool simplifies workflows by minimising rework and finishing. The focused cutting depth and precise 26 mm diameter support consistent hole tolerances and improved fit for bolts and dowels, while the HSS material balances toughness and wear resistance for longer service life. For procurement teams, the proven design reduces machine downtime and supports predictable maintenance planning.

FAQ

What materials is this annular cutter suitable for? The RUKO annular cutter (annular cutter, SKU 4000602305NW) is suitable for steel, cast iron and non‑ferrous metals, as specified for heavy‑duty structural and light alloy work.

Does the Weldon shank fit standard magnetic drills? Yes. The Weldon shank 19.05 mm (3/4") on the RUKO annular cutter provides secure clamping in common magnetic drill arbors and compatible arbor systems.

Is a pilot hole required before using this cutter? Typically no pilot hole is necessary for annular cutters of this type; the RUKO annular cutter is designed to cut directly when used with a suitable centring pilot on the drill unit.

How does an annular cutter differ from a twist drill? An annular cutter removes only the material at the hole perimeter, producing a solid slug and requiring less thrust than a twist drill; this results in faster, cleaner holes with reduced machine load when using the RUKO cutter.
