Core Drill D70 mm (Solid Carbide) – 50 mm Cutting Depth, RUKO

A Core Drill D70 mm (Solid Carbide) designed for reliable core drilling in steel, cast iron and high‑alloy materials for industrial and workshop use

• Solid-carbide for heavy-duty use
• 50 mm cutting depth for deep cores
• Quick IN 18 mm shank for fast mounting
• Suitable for steel, cast iron and high‑alloy steels

High-performance cutting for demanding materials

The solid carbide body and eight cutting edges deliver stability and consistent chip formation when working with tough workpiece materials. Solid carbide offers high rigidity compared with tool-steel alternatives, which reduces vibration and supports precise bore geometry; this makes the tool particularly effective when accuracy and repeatability are required. The combination of a 70 mm diameter and a 50 mm cutting depth enables the removal of substantial core sections without compromising surface finish, translating into fewer rework cycles and more predictable machining times.

Reduce machine downtime with secure, fast mounting

Equipped with the Quick IN 18 mm shank, the tool is intended for rapid clamping and repeatable concentricity in suitable holders. The Quick IN interface simplifies tool changes and shortens fixture time, supporting higher machine availability and more efficient shift planning. For production environments where changeover speed is a factor, the quick‑release shank reduces non‑productive time while maintaining a secure connection that preserves concentricity during high‑torque operations.

Engineered for rail, abrasion‑resistant and stainless steels

Designed specifically for heavy applications, the core drill is suitable for rail tracks and abrasion‑resistant steels such as Hardox or Weldox 400, as well as general steel, cast steel and high‑chromium stainless grades (V2A, V4A). The cutting geometry and carbide grade are selected to withstand the mechanical demands of these materials, offering a balance of edge strength and wear resistance. For machining tasks that involve frequent contact with high‑strength or work‑hardened surfaces, this design reduces the risk of premature tool wear and helps maintain hole integrity.

Professional workshop reliability and application guidance

Delivered as a single unit and intended for professional usage, the tool supports both one‑off repair work and series production. The robust construction and targeted application range make it a practical choice for maintenance departments, fabrication shops and industrial workshops that require dependable core drilling performance. For customers needing guidance on holder compatibility or machining parameters, technical consultation is available to ensure correct integration into existing machining setups.

FAQ

Which materials can this core drill machine?
The Core Drill D70 mm (solid carbide) is designed for heavy‑duty materials including rail tracks, Hardox/Weldox 400, general steel, cast steel and high‑chromium stainless steels such as V2A and V4A.

What is the effective cutting depth?
The tool provides a 50 mm cutting depth, suitable for producing deep cores in thick workpieces.

Which shank is required for mounting?
A Quick IN holder compatible with an 18 mm Quick IN shank is required for secure and repeatable mounting of the core drill.

Is this tool suitable for production environments?
Yes, the solid‑carbide construction and Quick IN interface make the drill appropriate for both maintenance work and serial production where durability and fast changeovers are needed.

How many cutting edges does the tool have and why does that matter?
The tool features eight cutting edges, which contribute to stable cutting behaviour, improved surface finish and balanced load distribution during core removal.
