Ruko annular cutter 18 mm HSS — 30 mm cutting depth

Ruko annular cutter 18 mm HSS — 30 mm cutting depth is a heavy-duty core drill designed for fast, clean holes in structural steel and a wide range of metals

• HSS construction for long tool life
• 30 mm cutting depth for efficient core removal
• Weldon shank 19.05 mm (3/4") for secure clamping
• Suitable for steel, cast iron and non‑ferrous metals

Precision holemaking with high‑performance HSS

This annular cutter combines the proven cutting properties of HSS with a geometry optimised for metalworking, delivering precise hole edges and reduced burr formation. The tool’s design concentrates the cutting forces at the circumference so that the central core is retained rather than pulverised; this reduces spindle load and speeds up chip evacuation. For workshops requiring consistent diameters in structural components, the cutter offers reliable repeatability and straightforward handling.

Faster cycle times through efficient cutting geometry

With five cutting edges, the cutter removes material quickly while distributing wear evenly, which decreases regrinding frequency and downtime. The specified 30 mm cutting depth allows through‑hole or deep pocketing in thicker sections without multiple passes, improving throughput on production and maintenance tasks. The combination of material choice and flute layout supports higher feed rates where machine rigidity and clamping permit, translating into measurable time savings on repetitive operations.

Broad material compatibility for versatile use

Manufactured from HSS, this core drill is suitable for a wide array of materials encountered in workshops: structural steel profiles, steel castings, aluminium and other light alloys, and many non‑ferrous metals. The cutter’s geometry and material grade balance toughness with edge retention, which means fewer tool changes when shifting between jobs. Where specialised alloys are in use, selection of cutting parameters ensures optimal results without compromising surface finish.

Stable clamping and simple integration into workflow

The Weldon shank (19.05 mm / 3/4") provides secure fixation in Weldon‑type holders or compatible toolholders, reducing slippage and improving concentricity during drilling. This shaft style is widely supported on magnetic drills and dedicated holders, allowing immediate integration into existing tooling systems. The solid construction and compact overall length support access in confined spaces while maintaining axial stiffness for clean, round holes.

FAQ

What materials can be machined with this annular cutter?
The Ruko annular cutter is suitable for machining steel, steel castings, and a range of non‑ferrous and light metals when used with appropriate speeds and feeds.

Which shank system is required for secure clamping?
A Weldon‑type holder that accepts a 19.05 mm (3/4") shank is required to secure the cutter correctly and maintain concentricity during drilling.

How deep can this cutter drill in a single pass?
The cutter provides a 30 mm cutting depth, enabling single‑pass core removal up to that depth depending on material and machine rigidity.

Is this tool suitable for magnetic drill presses?
Yes, the Weldon shank and compact overall length make the cutter compatible with magnetic drill setups that accept Weldon‑style holders.

How many cutting edges does the cutter have and what is the benefit?
The cutter features five cutting edges, which helps distribute wear and supports faster material removal with improved surface finish.
