Core drill Ø19 mm — solid carbide, 50 mm cutting depth (Ruko)

The Core drill Ø19 mm is a heavy‑duty annular cutter engineered for demanding work on high‑alloy steels and rails, offering a 50 mm cutting depth and a Quick IN 18 mm shank for fast tool changes

• Solid carbide construction for durability
• 50 mm effective cutting depth for deep holes
• Quick IN shank 18 mm for rapid changeovers
• Suitable for Hardox, Weldox 400 and V2A/V4A steels

High productivity and material versatility for industrial applications

The annular cutter’s solid carbide build delivers consistent edge stability under high load, enabling efficient machining of a wide range of challenging materials. With a 50 mm cutting depth and a nominal Ø19 mm diameter, the tool is optimised for fabricators and maintenance teams who require precise through‑holes without excessive axial force. Compatibility with Hardox, Weldox 400, railway rails and high‑chromium grades such as V2A and V4A reduces the need for multiple specialised cutters and streamlines workshop tooling inventories.

Reduced downtime through rapid clamping and robust geometry

The Quick IN shank 18 mm provides secure seating and extremely fast changeovers in compatible holders, cutting valuable minutes from tool changes during shift work. The cutter’s five cutting edges ensure balanced engagement and an even wear profile, which supports longer intervals between regrinds and replacement. The overall length of 83 mm combines reach with rigidity, so holes remain true while chip loads are distributed across multiple edges for improved surface finish and fewer heat hotspots.

Practical explanation of function and benefit for everyday workshop use

As an annular cutter, this tool removes a ring of material rather than the full core, lowering drilling forces and reducing energy consumption compared with solid twist drilling at the same diameter. The solid carbide composition offers superior hardness and wear resistance, which is particularly relevant when working with high‑alloy and heat‑treatable steels. For teams unfamiliar with annular cutters, this means faster cycles, cleaner holes and less strain on magnetic bases and drilling rigs during repetitive production tasks.

Application scenarios and reliability for heavy‑duty tasks

Designed for heavy fabrication, rail maintenance and workshop production, the cutter is a practical choice where repeatability and uptime matter. Its geometry and carbide cutting edges are tailored to maintain cutting efficiency in steel, cast steel and higher alloy metals, helping to ensure consistent hole quality across batches. Where speed and reliability are priorities, the combination of solid carbide construction and Quick IN mounting supports uninterrupted workflows and predictable tool life, reducing administrative overhead for inventory turnover.

FAQ

What materials can this core drill machine through?
The Ruko core drill is suitable for a broad range of steels including Hardox, Weldox 400, general structural steel, steel castings and higher‑alloy stainless grades such as V2A and V4A.

Is the shank compatible with standard tool holders?
The cutter is fitted with a Quick IN shank 18 mm, designed for quick clamping systems compatible with Quick IN tool holders; compatibility should be verified with the selected holder type.

How many cutting edges does the cutter have and why does that matter?
This annular cutter has five cutting edges; the multiple‑edge geometry spreads the cutting load, improving finish and extending the service life compared with fewer‑edged variants.

Can the core drill be used for rail maintenance?
Yes, the tool is specified for heavy applications including railway rails, where the solid carbide design supports the demands of frequent, high‑force drilling operations.
