RUKO Core Drill D25 mm – HSS, 30 mm cutting depth (Weldon shank)

A RUKO Core Drill D25 mm designed for reliable metalworking: precision holemaking in steel, cast iron and non‑ferrous alloys with an industrial Weldon shank for secure mounting

High-speed steel for long tool life
30 mm effective cutting depth
Weldon 3/4" shank for secure clamping
Suitable for steel, cast iron and non‑ferrous metals

Precision holes with durable HSS cutting geometry

Built from high-speed steel (HSS), the core drill delivers durable cutting performance and consistent hole quality. The 25 mm diameter and the cutter's ground geometry provide stable cutting forces, which reduces the need for rework and minimises scrap. For everyday workshop tasks this means predictable hole tolerance and fewer tool changes, improving throughput without sacrificing accuracy.

Stable mounting for heavy-duty machining

The Weldon shank design with a 3/4" flat ensures a positive drive and secure clamping in standard arbors and hydraulic chucks. This type of shank prevents rotation slip under torque and reduces runout during plunge operations, so the hole form remains true when working with thick plates or structural sections. The result is safer, more reliable machining and less downtime due to tool slippage.

Versatile across common industrial materials

Optimised for a broad range of materials, the cutter is suitable for steel (including T‑beams and large plates), cast iron and various non‑ferrous metals. The specified 30 mm cutting depth is ideal for through holes or controlled depth holes in medium‑thickness components; for much thicker sections, staged drilling or a longer core drill is advisable. The material versatility supports mixed production runs and reduces the need for specialised tool inventories.

Practical workshop benefits and efficient chip control

With a 63 mm overall length and 6 cutting edges, the tool combines compact handling with effective chip evacuation for interrupted or continuous cutting. The multi‑edge geometry spreads wear and aids heat dissipation, extending tool life in routine industrial applications. Delivered as a single unit, this core drill simplifies stock management and integrates smoothly into existing machining cells or portable drilling setups.
