23mm Core Drill HSS 55mm Cutting Depth Weldon Shank 3/4" - Ruko GmbH

Take advantage of the combination of durable HSS construction, a secure Weldon 19.05 mm (3/4") shank and a 55 mm cutting depth for reliable holemaking in structural steel and non‑ferrous metals; order directly via Metav Werkzeuge or consult the specialists for selection and compatibility advice.

RUKO Annular Cutter D23 mm HSS — 55 mm cutting depth, Weldon shank

A RUKO annular cutter engineered for efficient metal removal in demanding workshop and fabrication environments, suited to steel profiles, castings and light metals.

• High-performance HSS construction
• 55 mm cutting depth
• Weldon 3/4" shank for secure clamping
• Suitable for steel and non-ferrous metals

Faster cycle times with high-performance cutting

The annular cutter is made from HSS, delivering a balance of edge stability and toughness for repetitive holemaking. With a 23 mm diameter and 55 mm cutting depth, the tool removes only the material at the hole perimeter rather than the entire core, which reduces machining time and strain on equipment. The six cutting edges geometry provides efficient chip formation and a cleaner bore, translating into shorter cycle times and less rework in production runs.

Secure clamping reduces runout and downtime

A Weldon shank 19.05 mm (3/4") ensures a firm mechanical hold in compatible cutter holders and arbors, which limits axial and radial movement during drilling. Reduced runout directly improves hole accuracy and tool life, particularly when working with large structural components such as T‑beams or thick plate. The robust shank design also simplifies changeovers on magnetic and portable drilling rigs, contributing to steady uptime in the workshop.

Broad material compatibility for versatile workshop use

Designed to machine steel, steel castings, non‑ferrous and light metals, the cutter is suitable for common fabrication tasks and maintenance work. The HSS grade maintains cutting performance across these substrates and tolerates interrupted cuts encountered on welded assemblies and multi‑material setups. For operators, this means fewer tool changes and a single cutter can cover a wider range of daily applications.

Compact overall length for accessible holemaking

With a total length of 88 mm, the cutter integrates easily into standard annular cutter holders and magnetic drills while maintaining sufficient engagement for deep holes. The annular design minimises thrust compared with solid twist drills, which benefits both handheld and machine setups by lowering spindle load and improving finish. Routine resharpening of the cutting head will restore performance and extend service life when required.

FAQ

What materials can this annular cutter machine?
The RUKO annular cutter is specified for steel, steel castings and non‑ferrous and light metals; it is intended for structural and workshop use where HSS performance is appropriate.

Is the Weldon shank compatible with standard holders?
Yes. The Weldon 19.05 mm (3/4") shank is a common industrial standard and fits tooling arbors and holders designed for a 3/4" Weldon connection.

How does an annular cutter differ from a twist drill?
An annular cutter removes only the material at the hole circumference, producing faster cuts and lower thrust than a solid twist drill of the same diameter; this improves efficiency and reduces load on the drilling machine.

Can the cutter be resharpened?
The cutting head geometry of the annular cutter is suitable for professional resharpening services; returning the cutter to original geometry restores performance and extends tool life.

Which machines are recommended for use with this cutter?
The cutter is suitable for magnetic base drills and machine-mounted arbors that accept 3/4" Weldon shanks; ensure machine capacity matches the 23 mm diameter and the required machining conditions.
