Core drill D50 mm — Solid carbide, 50 mm cutting depth (Ruko)

Core drill D50 mm — a hardened-material cutter with a Quick IN shank for heavy-duty through-hole drilling in rails, Hardox grades and stainless steels

• Solid carbide construction
• 50 mm cutting depth
• Quick IN 18 mm shank
• Eight cutting edges for fast removal
• Suited for high-alloy steels and rails

High-performance drilling in abrasion-resistant and alloyed steels

The solid carbide design delivers exceptional rigidity and wear resistance when working in demanding materials such as railway rails, Hardox/Weldox 400 and high-chrome steels. This robustness translates into fewer tool changes and steadier bore quality, which supports continuous production runs. The tool’s geometry reduces vibration and helps maintain concentricity, so the result is cleaner cores with predictable tolerance retention — a direct benefit for workshops processing heavy plate or rail sections.

Efficient material removal with eight cutting edges

Equipped with eight cutting edges, the cutter achieves high removal rates while distributing cutting forces evenly across the circumference. This configuration minimises local overheating and extends usable tool life compared with fewer-edged designs. For operators unfamiliar with the term: multiple cutting edges mean each tooth takes a smaller chip, lowering load per edge and improving chip evacuation — especially helpful when penetrating stainless or high-alloy workpieces where heat management is critical.

Faster tool changes and secure mounting with Quick IN

The Quick IN shank (18 mm) enables rapid, repeatable tool changes on compatible holders, reducing downtime at tool stations. The 18 mm shank provides a secure clamping interface for stable rotation at moderate feeds; combined with the cutter’s 50 mm cutting depth and overall length 112 mm, this makes the tool suitable for standard through-hole operations without excessive overhang. For production environments, that means improved throughput and fewer interruptions during shift work.

Application logic and workshop benefits

This core cutter is engineered for operations where reliability matters: drilling into steel, cast steel, stainless grades V2A/V4A and other high-alloy materials is feasible because of the carbide substrate and robust geometry. The tool’s profile aids hole centring and reduces the need for extensive rework, saving downstream finishing time. For procurement and workshop managers, the combination of diameter 50 mm, durable carbide composition and the Quick IN interface represents a pragmatic balance of performance and process efficiency.
