RUKO Core Drill Ø12 mm HSS – 30 mm cutting depth, Weldon shank

RUKO Core Drill Ø12 mm HSS – a high-performance core drilling solution for producing precise holes in steel, cast components and non‑ferrous metals, fitted with a 3/4" Weldon shank for reliable clamping

• High-performance HSS construction
• 12 mm diameter for precise core holes
• 30 mm effective cutting depth
• Weldon shank 19.05 mm for secure clamping

Reduced cycle times through efficient cutting

The HSS composition delivers a reliable balance of hardness and toughness, allowing the core drill to sustain sustained cutting in demanding shop environments. Combined with four cutting edges, the geometry reduces vibration and promotes fast chip evacuation, which translates into shorter cycle times and fewer tool changes. The 30 mm cutting depth is optimised for typical structural and fabrication tasks, and the 63 mm total length keeps the tool compact for use in confined set-ups while still providing the working reach required for stand‑alone drilling and machine use.

Secure mounting and consistent hole quality

A Weldon shank of 19.05 mm (3/4") ensures positive clamping in standard toolholders and magnetic chucks, preventing slippage under load and supporting repeatable centre alignment. The robust connection between holder and cutter improves concentricity and delivers precision hole geometry, which reduces the need for secondary rework. For production lines and toolrooms where dependable clamping is essential, this design feature contributes directly to process stability and predictable output quality.

Versatile application across common workshop materials

Designed for a range of substrates, the tool is suitable for steel (including structural profiles and large plates), cast steel and non‑ferrous and light metals, enabling consolidation of tooling across multiple tasks. The combination of HSS material and the cutter geometry supports machining at moderate speeds and provides durability under intermittent heavy use. For workshops that require a compact, rugged solution for through and blind holes in mixed materials, this cutter offers a practical balance of performance and service life.

FAQ

What materials can this core drill machine?
The RUKO core drill is engineered for steel, cast steel and non‑ferrous and light metals, making it suitable for general fabrication and maintenance tasks.

Is the shank compatible with standard toolholders?
Yes, the Weldon shank (19.05 mm / 3/4") on the RUKO core drill is intended for secure clamping in standard holders and magnetic chucks.

How does the HSS material affect tool life?
HSS provides a balance of hardness and toughness; the RUKO HSS construction supports durability under typical workshop speeds and intermittent heavy loads.

How many cutting edges does the tool have and what is the benefit?
The core drill features four cutting edges, which promote stable cutting, improved chip removal and consistent hole quality.

Can this cutter be used in confined set-ups?
With a total length of 63 mm and a 30 mm cutting depth, the cutter is compact enough for use in tighter set‑ups while offering sufficient reach for common drilling tasks.
