Ruko core drill Ø13 mm — solid carbide, 50 mm cutting depth

The Ruko core drill Ø13 mm is a solid-carbide hole cutter designed for fast, precise core drilling in high-strength steels and heavy-duty applications.

• Solid carbide construction for highest wear resistance
• 50 mm cutting depth for deep-core applications
• Quick IN 18 mm shank for rapid tool changes
• Four cutting edges for clean core extraction

High-performance drilling for demanding steels

The solid carbide geometry keeps cutting forces low while delivering repeatable hole quality in challenging materials. With a 50 mm cutting depth and a nominal diameter of Ø13 mm, the cutter is optimised for core removal rather than through-hole finishing. The combination of rigid carbide and a compact total length of 83 mm reduces vibration and runout, which translates into more accurate hole centres and longer tool life. This performance-oriented configuration supports production environments where cycle time and first-pass accuracy matter.

Fast handling and reduced downtime

A Quick IN shank with an 18 mm diameter enables swift tool changes on compatible holders and magnetic chucks, shortening non-productive time between operations. The tool’s four cutting edges ensure a controlled chip flow and smoother core ejection, which reduces the need for rework. For workshop managers, the practical benefit is greater throughput per spindle hour and less time spent on secondary operations. Tool set-up and removal become straightforward tasks in busy cell layouts.

Broad material capability explained

The cutter is specified for heavy-duty materials, including railway rails, Hardox/Weldox 400 grades and various high-chromium steels such as V2A and V4A, as well as general steel and cast steel. Solid-carbide construction permits operation at higher surface speeds than HSS equivalents, improving penetration rates in hardened or highly alloyed steels. When used with adequate cutting fluid and appropriate feed rates, the bit delivers clean cores and consistent wall finishes in these demanding substrates.

Practical operation and safety considerations

Operation with correct clamping and steady spindle support is recommended to exploit the tool’s precision. The short overall length minimises bending moments, so a stable machine setup yields the best results. Regular inspection of the cutting lips and attention to coolant application extend tool life and maintain hole quality. For applications involving abrasive or hardened surfaces, monitoring cutting temperatures and adjusting feed to maintain a consistent chip load will protect the carbide geometry.
