Core drill Ø30 mm, HSS, 55 mm cutting depth — Weldon shank by Ruko

The Core drill Ø30 mm, HSS, 55 mm cutting depth is a high-performance core drill for demanding metalworking tasks, designed for use in fabrication, maintenance and heavy workshop applications.

• High-performance HSS material
• Weldon 19.05 mm (3/4") shank for stable clamping
• 55 mm cutting depth for deep cores
• Suitable for steel, cast iron and non‑ferrous metals

Exact material performance for demanding metals

Manufactured from HSS, this core drill delivers consistent cutting performance when working with structural steel, cast iron and a range of non‑ferrous and light metals. The 30 mm diameter combined with a 55 mm cutting depth enables precise core removal in applications such as large-format plate work and structural sections. Using high-speed steel ensures a balance between toughness and wear resistance, which supports longer interval times between tool changes and reduces downtime in production.

Stable clamping and machine compatibility for safer operation

The Weldon shank design at 19.05 mm (3/4") provides secure engagement in standard Weldon holders and compatible chucks, reducing slippage under load and lowering the risk of runout. Stable clamping translates into improved surface quality of the drilled core and safer operation on radial drills or drill presses that accept Weldon tooling. This mechanical interface supports repeatable positioning and consistent concentricity, which is particularly important when preparing mating faces or bolt holes.

Efficient geometry and controlled chip evacuation

Equipped with eight cutting edges, the geometry promotes effective material removal and cleaner core extraction, which reduces rework and accelerates throughput. The cutting-edge arrangement balances cutting forces and aids chip control in mixed-metal applications, improving heat distribution and extending the serviceable life of the tool. Where necessary, operators can pair the drill with appropriate coolant or cutting fluid to maintain performance during extended runs.

Practical application guidance for workshop use

This core drill is intended for professional environments such as fabrication shops, plant maintenance and metalworking contractors, where the combination of durability and straightforward handling matters. Typical tasks include drilling through T‑beams, large plates and assemblies made from steel, cast components and brass or aluminium workpieces. The tool’s design simplifies setup in standard Weldon holders and integrates well into existing machining workflows, making it a pragmatic choice for busy workshops.
