Ruko Solid-Carbide Core Drill D26 mm — 50 mm Cutting Depth

A Ruko solid-carbide core drill engineered for heavy-duty holemaking in rail steels, Hardox/Weldox 400, stainless steels and cast materials, fitted with a Quick IN 18 mm shank for secure, fast changes

• Solid-carbide construction for high wear resistance
• 26 mm diameter with 50 mm cutting depth
• Quick IN 18 mm shank for fast tool changes
• Suitable for Hardox, Weldox, rail and stainless steels

Precision and durability for demanding materials

The solid-carbide design delivers consistently high edge stability and wear resistance when machining challenging alloys. With six cutting edges arranged for efficient chip evacuation, the cutter produces clean holes in abrasive and high-strength materials while maintaining dimensional stability. This geometry reduces rework and contributes to predictable tool life, an important factor when drilling series holes in structural components or repair jobs on rail profiles.

Optimised dimensions and fast tool changes

A nominal 26 mm diameter combined with a 50 mm cutting depth and 83 mm overall length provides a balance between reach and rigidity for common through-holes and blind holes in structural parts. The Quick IN shank (18 mm) enables secure fitting in compatible holders and reduces non-productive time during tool changeovers. The interface is suitable for systems accepting Quick IN tooling, ensuring straightforward replacement and alignment on dedicated drilling rigs or portable holders.

Application range and workshop benefits

Designed for demanding applications, the annular cutter is appropriate for rail steels, Hardox/Weldox 400, steel, cast steel and high-chrome grades (V2A, V4A). The robust construction supports efficient holemaking in maintenance, fabrication and heavy engineering contexts, improving productivity through fewer tool swaps and more consistent hole quality. For workshops seeking an economical route to precision, the cutter offers reliability and the operational advantages of carbide tooling without sacrificing hole finish.
