Ruko Annular Cutter D32 mm (HSS, 30 mm cutting depth) – Weldon shank

The Ruko Annular Cutter D32 mm is a high-performance HSS core drill designed for efficient holemaking in steelwork, cast components and non-ferrous metals.

• HSS construction for high wear resistance
• 30 mm cutting depth for thicker workpieces
• Weldon shank 19.05 mm (3/4") for secure clamping

Faster, cleaner holes in structural steels

Constructed from HSS, this annular cutter delivers a balance of hardness and toughness that suits demanding fabrication. The tool's 32 mm diameter and 30 mm cutting depth allow effective penetration of medium-thickness sections while the design with 8 cutting edges produces a clean bore with reduced burr formation. Compared with solid twist drills, the annular principle removes a ring of material rather than the full core, so less power is required and heat buildup is minimised, leading to longer tool life and fewer workpiece reworks.

Secure mounting and stable machining

The Weldon shank (19.05 mm / 3/4") ensures a positive mechanical lock in compatible holders and magnetic drilling bases, improving concentricity and reducing vibration during cutting. This secure interface supports consistent cutting geometry and makes tool changes straightforward under workshop conditions. The overall length of 63 mm provides sufficient engagement for guided drilling heads while maintaining compact handling, so setup times are shortened and throughput increases in repetitive holemaking tasks.

Broad workshop applications and practical benefits

Suitable for a wide range of materials—structural steels such as T‑beams and large-format plates, cast steel, and various non‑ferrous and light metals—the cutter supports common fabrication and maintenance operations. The compact cutting depth and efficient chip removal make it a practical choice for on-site metalwork and production environments where cycle time and reproducible hole quality matter. Supplied as a single unit, the tool integrates into existing tooling systems with minimal adaptation and delivers a measurable improvement in process reliability.

FAQ

Which materials can this annular cutter process?
The Ruko annular cutter is suitable for steel (including structural profiles), cast steel and a range of non‑ferrous and light metals according to the tool’s design and cutting parameters.

What is the exact shank size and how is it held?
The tool features a Weldon shank of 19.05 mm (3/4"), designed for secure clamping in Weldon adapters and compatible magnetic drilling systems.

How deep can the cutter bore in a single pass?
The cutter provides a cutting depth of 30 mm with an overall length of 63 mm, which corresponds to the effective depth for standard fabrication tasks.

How does an annular cutter differ from a twist drill?
An annular cutter creates a ring-shaped cut, removing only the material around the hole perimeter; this reduces required power and chip volume compared with a twist drill, enabling faster, cleaner holes for larger diameters.

How many cutting edges does the tool have and what is the benefit?
This Ruko core drill has 8 cutting edges, which contribute to smoother cutting action, improved surface finish and a more even distribution of cutting forces.
