Precision and durability for hard metals

The solid-carbide design delivers a high hardness and thermal resistance that sustains cutting performance in abrasive and heat-generating conditions. Combined with six cutting edges, the bit achieves a more uniform chip formation and reduced vibration, which translates into faster material removal and extended tool life when working with high-chromium stainless steels, cast steel and structural alloys. The specified 25 mm diameter and 50 mm cutting depth provide a clear capacity for through-holes and recessed drilling tasks, while the overall 83 mm length keeps the tool compact for confined setups.

Fast tool changes and secure mounting

Equipped with a Quick IN 18 mm shank, the drill is designed for rapid insertion and release in compatible chucks, reducing non-productive time during tool swaps. The secure shank geometry contributes to improved runout control and repeatable concentricity, which is particularly important when machining components such as rails or welded steel assemblies. For production settings where cycle time and repeatability are decisive, this quick-change system supports consistent output without compromising cutting quality.

Suited applications and operational benefits

Specifically intended for heavy-duty tasks, the tool is effective on rails, Hardox/Weldox 400 and a variety of steels including V2A and V4A grades. The combination of carbide cutting edges and the sturdy shank ensures stable performance in workshop and site repair operations alike. Operators will value predictable hole quality and fewer tool changes, while maintenance teams benefit from the reduced frequency of replacements thanks to the wear-resistant carbide composition.

Handling, compatibility and workshop integration

The core drill arrives as a single packaged unit and is compatible with systems that accept the Quick IN shank size. As a solid-carbide option, it offers a distinct advantage over high-speed steel in terms of temperature tolerance and wear resistance when machining tougher alloys. For integration into existing workflows, ensure the host machine or adapter supports the Quick IN 18 mm interface to fully exploit the tool’s rigidity and quick-change capability.
