Core drill Ø12 mm, solid carbide – 50 mm cutting depth | Ruko

The Core drill Ø12 mm (solid carbide, Quick IN shank) delivers precise core removal in hard and alloyed steels for demanding industrial applications.

• Solid carbide construction for high wear resistance
• 50 mm effective cutting depth for deep cores
• Four cutting edges for smooth, accurate cuts
• Quick IN 18 mm shank for fast tool changes

High-performance core drilling for hardened and wear-resistant steels

The solid carbide design of this core cutter provides consistently high hardness and abrasion resistance, which translates into longer service life under heavy demands. With four cutting edges, chip formation is stabilised and vibration is reduced, producing a cleaner bore and extending tool life. This combination is especially beneficial when working on Hardox/Weldox 400 and other high-strength steels, where conventional tools wear rapidly. The technical build reduces unplanned downtime and maintains machining accuracy across extended production runs.

Fast changeover and secure clamping for efficient workflows

Equipped with an 18 mm Quick IN shank, the tool allows rapid insertion and secure retention in compatible tool holders, streamlining tool changes and minimising machine idle time. The 50 mm cutting depth supports deeper core extraction without stopping for additional passes, improving throughput on repetitive tasks. For workshops seeking consistent cycle times, the quick-change interface simplifies logistics and reduces the need for complex fixture setups.

Application-focused performance and material compatibility

This core drill is engineered for applications that demand toughness and precision: railway rails, wear plates and thick, alloyed steels, plus steel castings and high-chromium grades such as V2A/V4A. The robust carbide cutting edges maintain sharpness under heavy loads, enabling reliable penetration in materials that typically blunt HSS tools. Where accuracy and repeatability matter, the tool delivers clean cores and predictable chip evacuation, making it suitable for industrial repair, fabrication and heavy maintenance environments.

Practical handling and workshop integration

The geometry and edge count are selected to balance cutting forces and surface finish, yielding cores that require minimal deburring. The Quick IN interface supports modular tooling strategies, allowing the cutter to be integrated into a variety of holders and adaptors. Maintenance routines are straightforward: inspect the carbide edges for wear and replace the cutter when the specified tolerances cannot be maintained. For procurement and bulk-supply planning, Metav Werkzeuge provides dependable delivery from stock in Emmerich and can advise on compatible holders and feed parameters.
