Six cutting edges for stable, fast drilling

Durable carbide design for demanding materials

The carbide body provides outstanding wear resistance and dimensional stability during prolonged use. With solid carbide geometry and six cutting edges, the tool resists deformation when working on abrasive or highly alloyed steels. This construction reduces the frequency of tool changeovers and maintains hole tolerance, which is particularly beneficial in production environments and field repairs where consistent results are required. The combination of hardness and edge stability supports reliable performance on materials listed below.

Designed for heavy-duty and abrasive steels

The drill is specified for tough materials including rails, Hardox/Weldox 400 wear steels, general steel and cast steel, and high-chromium stainless grades such as V2A and V4A. The cutter geometry and edge count promote controlled chip formation and evacuation when cutting into these difficult substrates, which lowers the risk of chatter and improves surface finish inside the bore. For fabrication shops and maintenance teams, this translates into fewer reworks and predictable cycle times when producing core holes up to the drill’s maximum cutting depth.

Productivity through cutting depth and compact dimensions

With a nominal diameter of 23 mm and a 50 mm cutting depth within an overall length of 83 mm, the tool balances reach and rigidity to deliver efficient holemaking without excessive overhang. The available cutting depth covers typical through-holes and many blind-hole tasks encountered in structural and rail applications. The compact total length helps to maintain stiffness at the cutter, contributing to cleaner bores and extended insertible life compared with longer, more flexible alternatives.

Quick IN shank for rapid changeovers and secure clamping

The Quick IN 18 mm shank supports rapid tool changes and stable clamping in compatible holders. This feature reduces machine downtime during tool rotations in busy workflows and simplifies setup for series production or on-site maintenance. The shank standard also aids repeatability when paired with quick-change systems commonly found in industrial drilling rigs and service equipment, allowing teams to focus on throughput rather than tool handling.

Practical workshop advantages and target uses

This core drill suits industrial users, maintenance crews and specialist fabricators working in rail, heavy machinery and wear-resistant fabrication. The combination of solid carbide construction, stable multi-edge geometry and a quick-change shank is aimed at delivering dependable hole quality in tough-to-machine materials. For workshops looking to consolidate tooling for high-alloy and abrasion-prone jobs, this drill reduces tool inventory complexity while maintaining performance where it matters most.
