RUKO Core Drill, 27 mm HSS, 30 mm Cutting Depth – Weldon Shank

A RUKO Core Drill designed for precision holemaking in steel, cast iron and light metals, featuring a Weldon shank for secure clamping

• 27 mm diameter for standard hole sizes
• 30 mm effective cutting depth
• Weldon shank 19.05 mm (3/4") for secure clamping
• High-speed steel for steel and non-ferrous metals

Faster, consistent holemaking in ferrous and non-ferrous materials

The combination of HSS construction and a 27 mm bore makes this core drill a dependable choice where clean, repeatable holes are required. The tool’s 30 mm cutting depth and 7 cutting edges permit controlled material removal in sections such as T‑beams and large plates, reducing the need for secondary finishing. For workshops with mixed production runs, this configuration balances chip evacuation and durability so that hole quality remains consistent across steel, cast iron and light alloys.

Stable clamping and reduced runout for improved surface finish

A Weldon shank (19.05 mm / 3/4") secures the drill reliably in standard holders and arbors, which helps to minimise runout and vibration during cutting. Less runout translates into a better surface finish and lower tool stress; the firm clamping also simplifies set‑up time on the bench or in jigged fixtures. Where torque transfer and lateral stability matter, the Weldon interface delivers practical advantages over plain cylindrical shanks.

Workshop compatibility and straightforward integration

With an overall length of 63 mm the tool integrates well with compact holders and short‑reach setups, keeping the assembly rigid and accessible. Made from high-speed steel, the core drill suits typical workshop operations and is compatible with hand and machine drilling where precision and repeatability are required. Metav’s expertise in precision tooling ensures the product arrives with clear expectations for application and handling, supporting efficient procurement and reliable supply to the workbench.
