Core drill Ø28 mm HSS, 30 mm cutting depth, Weldon shank – RUKO

The Core drill Ø28 mm HSS is a compact, industrial-grade tool designed for efficient core drilling in steel, castings and light metals with a secure Weldon shank for vibration-resistant clamping

• High-speed steel body for industrial use
• 28 mm diameter for substantial core removal
• 30 mm effective cutting depth
• Weldon 3/4" shank for secure clamping

Higher throughput with industrial-grade cutting performance

The high-speed steel (HSS) construction delivers a balance of hardness and toughness that supports sustained cutting under industrial conditions. With a 28 mm diameter and 30 mm cutting depth, the tool enables substantial core removal in fewer passes, reducing cycle times on large-format plates and profiles. The seven cutting edges facilitate even material evacuation and a steady feed, which translates into measurable production gains in workshop and fabrication environments.

Secure clamping and dimensional stability for reliable machining

A Weldon shank (19.05 mm / 3/4") ensures firm, concentric clamping in standard toolholders and stands up to lateral forces during core extraction. The shank design reduces chatter and runout, improving hole quality and repeatability. For operators seeking consistent bore diameters and a reduced need for rework, this shank type is a practical choice that supports precise positioning and safer tool changes.

Broad material compatibility for versatile workshop use

Engineered for demanding applications, the cutter is suitable for steel, steel castings, and a range of non-ferrous and light metals. The material selection and geometry permit effective use on T-profiles, large sheets and thicker sections where core removal is required. Clear labelling of material suitability aids process planning and supports efficient tool selection for mixed production runs.

Practical handling and integration in machine setups

With an overall length of 63 mm and a compact form factor, the tool integrates easily into common drilling rigs and machining setups where access is limited. The combination of compact length and robust shank allows closer approach to fixtures and reduces overhang—benefits that improve rigidity and surface finish. For facilities standardising tooling, the Weldon shank supports quick interchange across compatible holders and chucks.

FAQ

What materials can be machined with this core drill?
The RUKO core drill in HSS is suitable for steel, steel castings and a range of non-ferrous and light metals, making it versatile for fabrication and maintenance tasks.

Which shank size does the tool use and why is that important?
The tool features a Weldon shank of 19.05 mm (3/4"), which enables secure clamping in standard holders and reduces runout for improved bore accuracy.

How deep can this core drill cut in a single pass?
The core drill provides a cutting depth of 30 mm, enabling substantial core extraction per operation while maintaining stability.

Is the tool compatible with handheld drills or only machine setups?
Due to the Weldon shank and industrial HSS design, the cutter is intended primarily for machine-mounted applications where secure clamping and rigidity are present.

How many cutting edges does the cutter have and what is the benefit?
The core drill has seven cutting edges, which support smoother cutting action and better material evacuation, reducing the risk of clogging during drilling.
