Ruko Core Drill D22 mm – Solid Carbide Annular Cutter, 50 mm Cutting Depth

The Ruko Core Drill D22 mm is a solid-carbide annular cutter designed for industrial holemaking in wear-resistant and high-alloy steels, fitted with a Quick IN 18 mm shank for fast tool changes

• Solid carbide construction
• 50 mm cutting depth
• Quick IN 18 mm shank
• Suitable for high-alloy and wear steels

Robust carbide design for consistent high-performance

A tool made from solid carbide combines hardness and thermal stability to deliver extended life in demanding applications. The cutter’s geometry and material reduce flank wear and preserve cutting edges under intermittent heavy loads. For production environments that demand predictable tool life, the combination of a carbide body and a precise fluting design supports higher cutting speeds and longer intervals between regrinds, enhancing overall process efficiency and reducing unplanned downtime.

Purpose-built for tough materials and clean bore quality

Engineered specifically for wear-resistant steels and alloyed grades, the cutter is effective on Hardox/Weldox family steels, cast steel and high-alloy stainless steels often encountered in rail and heavy engineering. The tool’s multiple flutes and six cutting edges distribute cutting forces evenly, producing clean bores with minimal burr and reduced need for secondary finishing. This performance is particularly beneficial where component tolerances and surface integrity are critical, such as in maintenance of rails or fabrication of welded assemblies.

Quick-change shank for lean tool handling and faster set-ups

The Quick IN shank (18 mm) supports swift insertion and positive clamping in compatible holders, cutting set-up times and improving throughput on machines with frequent tool changes. As an annular cutter, it removes material as a ring rather than chipping the whole core, which lowers power consumption compared with equivalent twist drills and reduces load on the machine spindle. The nominal 22 mm cutting diameter and overall length of 83 mm balance reach and rigidity for stable machining of medium-depth holes.

Practical advantages in workshop and production use

Beyond raw cutting capability, the design simplifies handling and maintenance: re-sharpening cycles are predictable, tool life can be optimised by matching cutting parameters to material grade, and the robust construction resists vibration-induced damage. For operations seeking to consolidate tooling without compromising on performance, this annular cutter offers a pragmatic trade-off between longevity and cutting speed while supporting continuous production demands.

FAQ

What materials is this core drill suitable for?
The Ruko Core Drill D22 mm is specified for railway rails, Hardox/Weldox 400, general steel, cast steel and high‑alloy stainless steels such as V2A and V4A.

How deep can the cutter drill in a single pass?
The tool provides a 50 mm cutting depth as standard, allowing efficient one‑pass holemaking for medium‑depth bores.

What shank type is fitted and what are the benefits?
Fitted with a Quick IN 18 mm shank, the cutter enables rapid tool changes and secure clamping for reduced setup times.

How many cutting edges does the cutter have and why does this matter?
The annular cutter has six cutting edges, which distribute forces and promote smoother cutting, better bore quality and longer edge life.

Is this tool suitable for use on rail maintenance and heavy engineering tasks?
Yes, the geometry and carbide grade are chosen to handle the abrasion and toughness typical of rail and heavy engineering materials while maintaining bore accuracy.
