Core drill Ø40 mm HSS — 30 mm cutting depth, Weldon shank (RUKO)

The Core drill Ø40 mm HSS is a compact high‑performance core bit for workshop and structural applications, designed to cut clean holes in steel, cast iron and light non‑ferrous metals.

• High‑speed steel construction
• 30 mm cutting depth for shallow cores
• Weldon shank 19.05 mm (3/4") for secure clamping
• Suitable for steel, cast iron and non‑ferrous metals

Faster material removal for routine and structural work

Constructed from high‑speed steel (HSS), this core tool delivers efficient chip evacuation and consistent cutting action across a range of construction and fabrication applications. The 40 mm diameter and 30 mm cutting depth are matched to common sheet and beam work where a controlled, shallow core is required; this reduces the need for secondary finishing and supports higher throughput on repetitive tasks. The HSS composition offers a balance of toughness and wear resistance, which supports longer service life under standard workshop conditions.

Secure clamping and steady, concentric cuts

A Weldon shank 19.05 mm (3/4") gives a positive mechanical drive and reduces slippage in set screws or holder systems, providing stability during heavy engagement. The shank format is compatible with standard Weldon holders and quick‑change adapters, ensuring concentric running and minimised run‑out for cleaner hole walls. Reduced vibration not only improves hole quality but also extends the lifetime of the tool and the machine spindle, supporting predictable process outcomes.

Versatile application and straightforward integration into workflows

Designed for use on steel, cast iron, and a variety of light and non‑ferrous alloys, the bit offers practical versatility for repair, installation and fabrication tasks. The available cutting edge count contributes to smooth cutting behaviour and consistent chip control when used with appropriate feed rates and lubricant or coolant. Integration into a workshop is uncomplicated: the bit mounts in common Weldon holders and is ready for standard bench drills, milling machines or portable drill rigs where a shallow core is required.

FAQ

What materials can this core drill process?
The RUKO core drill is suitable for steel, cast iron and a range of non‑ferrous and light metals, making it appropriate for structural and workshop applications.

Which shank system is required for secure mounting?
The tool uses a Weldon shank 19.05 mm (3/4"), so a Weldon holder or compatible clamping system is required for correct and secure mounting.

How deep can the drill cut in a single pass?
The core drill has a cutting depth of 30 mm, designed for shallow cores and through‑hole preparations where minimal secondary work is expected.

Is this core drill appropriate for portable rigs and bench drills?
Yes, the geometry and shank format allow use in standard bench drills, portable drill rigs and milling machines when the correct holder is fitted.
