RUKO Core Drill 26 mm – HSS core drill with 55 mm cutting depth and Weldon shank

The RUKO Core Drill 26 mm is a precision-engineered HSS core drill designed for medium-duty drilling in steel, cast iron and non‑ferrous metals, offering secure mounting and consistent hole quality for workshop and industrial use.

• High-speed steel construction
• 55 mm effective cutting depth
• Weldon shank 19.05 mm (3/4")
• Designed for steel, cast iron and non-ferrous metals

Efficient, high-performance metal cutting for production workflows

The combination of HSS material and a seven‑flute cutting geometry provides a balance of wear resistance and cutting efficiency for repetitive operations. With a 26 mm cutting diameter and a 55 mm cutting depth, the tool enables reliable hole-making in common structural components such as beams and large plates. Specified cutting dimensions translate directly into predictable cycle times and reduced tool change frequency, which supports steady production throughput and easier process planning.

Secure mounting and stable handling reduce downtime

A Weldon shank with a 19.05 mm (3/4") diameter ensures firm clamping in chucks and arbors typical for magnetic drills and pillar drills that accept Weldon tooling. The total length of 88 mm gives sufficient reach for standard setups while maintaining rigidity, reducing deflection and improving hole concentricity. These mechanical design choices mean fewer reworks and a robust fit-up during repetitive drilling tasks, supporting continuous operation in trade and industrial environments.

Clear application guidance and practical advantages on the shop floor

Intended for use on steel, cast iron and non‑ferrous metals, the core drill performs well where a defined bore depth and clean core removal are required. The multi-flute geometry—listed as 7 cutting edges—helps distribute cutting forces and improves chip formation compared with single-edge variants, which can ease chip evacuation and surface finish. Supplied as a single unit, the tool is suitable for workshops seeking a ready-to‑fit, durable drilling solution without extensive setup changes.

FAQ

What materials is this core drill suitable for?
The RUKO Core Drill 26 mm is suitable for steel (including structural sections and large plates), cast iron and non‑ferrous metals, as stated in the product specification.

What are the shank details and compatibility?
The core drill features a Weldon shank with a diameter of 19.05 mm (3/4"), designed for secure clamping in compatible chucks and arbors.

What are the cutting diameter and cutting depth?
The tool has a cutting diameter of 26 mm with an effective cutting depth of 55 mm and a total length of 88 mm.

How many cutting edges does the drill have and why does that matter?
The tool is specified with 7 cutting edges; multiple edges can distribute cutting forces more evenly and support smoother chip formation in many metalworking tasks.

How is the tool supplied?
The core drill is supplied in a packaging unit of 1, ready to be fitted into a compatible holder or chuck.
