Ruko Annular Cutter D55 mm – HSS, 30 mm Cutting Depth, Weldon Shank

A Ruko annular cutter designed for fast, clean boremaking in steel, cast iron and light alloys, ideal for structural and workshop applications

• High-performance HSS cutting edges
• 55 mm diameter for large boreholes
• 30 mm effective cutting depth
• Weldon 19.05 mm shank for secure clamping

Faster metal removal with high-speed steel performance

The HSS composition delivers a reliable balance of toughness and wear resistance for demanding holemaking tasks. With a 55 mm diameter and a 30 mm cutting depth, the tool removes material efficiently without excessive operator intervention, reducing total machining time. The design of the cutting lips and the number of cutting faces – supplied with multiple cutting edges – supports continuous metal removal in structural steel, cast iron and non‑ferrous metals. For workshops looking to streamline production, this cutter offers a predictable service life and consistent hole geometry, which helps to limit secondary operations and rework.

Secure clamping and stable operation reduce downtime

A Weldon shank of 19.05 mm (3/4") ensures positive axial and radial grip in standard Weldon holders, minimising slippage and runout under load. The result is improved concentricity and longer tool life, particularly when machining thick plates or T‑sections. The compact overall length of 63 mm keeps the cutter rigid in the holder, offering stability during plunge and peck cycles. These characteristics translate into fewer tool changes and less set‑up time per hole, supporting a more efficient workflow on fabrication benches and in maintenance departments.

Practical integration for workshop and industrial use

This annular cutter is suited for a wide range of applications where neat, burr‑reduced holes are required in metalwork: from large‑format plates to structural beams and light alloys. Supplied as a single unit, the tool is straightforward to store and identify in a tooling cabinet. The combination of material compatibility and a secure shank system means the cutter integrates easily into existing magnetic drills and machines equipped for Weldon holders, delivering repeatable results without additional adapters. For operations seeking dependable consumables, Metav’s supply chain from Emmerich offers steady availability and quality assurance.
