RUKO core drill D36 mm HSS – 30 mm cutting depth with Weldon shank

The RUKO core drill D36 mm is a high-performance HSS core drill designed for drilling clean, repeatable holes in steel, cast iron and non-ferrous metals for fabrication and maintenance tasks.

• High-performance HSS construction
• 36 mm diameter for precise core holes
• 30 mm cutting depth for clean extraction
• Weldon shank 19.05 mm (3/4") for secure clamping

Consistent metalworking results through material and geometry

The solid HSS body and the specified geometry deliver repeatable performance in demanding environments. With a nominal 36 mm diameter and a 30 mm effective cutting depth, the tool produces predictable hole sizes that simplify subsequent assembly or reaming steps. The presence of nine cutting edges ensures stable chip formation and uniform cutting forces, which reduces vibration and supports higher process reliability when used in conventional drilling rigs and portable units.

Secure mounting and reduced runout for accurate holes

The Weldon shank design with a 19.05 mm (3/4") flat provides a secure mechanical interface in standard Weldon holders and quick-change arbors. This form of clamping reduces axial slip and runout compared with cylindrical shanks, improving concentricity of the drilled hole. For workshops and on-site fabrication, the combination of a robust clamping standard and the tool’s mass distribution helps maintain tolerance control during longer production runs.

Broad application range for versatile workshop use

Engineered for general metal fabrication, the core drill is suitable for steel (including structural profiles and large plates), cast iron and various non-ferrous metals, supporting a wide spectrum of jobs from maintenance to production. The tool’s HSS composition ensures a balance of toughness and wear resistance for intermittent heavy-duty use. For procurement managers and workshop supervisors, this core drill offers a practical balance of durability and applicability across multiple material classes, reducing the need for specialised sets.

FAQ

What materials can be machined with this core drill?
The RUKO core drill D36 mm is suitable for steel, cast iron and a range of non-ferrous and light metals as stated in the technical description.

What shank system is required for use?
A Weldon holder that accepts a 19.05 mm (3/4") flat is required to secure the Weldon shank and achieve the intended concentricity.

How deep does the drill cut effectively?
The effective cutting depth is 30 mm, which is intended for through-holes or controlled core extraction to that depth.

How many cutting edges does the tool have and why does that matter?
The tool has nine cutting edges, which helps distribute cutting forces, improve chip control and stabilise drilling under load.

Can this core drill be used in a portable drill press on-site?
Yes, the geometry and Weldon shank are compatible with common portable and bench-mounted Weldon chucks used in on-site metalwork.
