Ruko core drill D.28 mm – solid carbide, 50 mm cutting depth, Quick IN shank

The Ruko core drill D.28 mm is a solid carbide, high-performance cutting tool for demanding industrial drilling tasks, designed for rapid holemaking with the Quick IN shank system

Solid carbide construction for hard materials
28 mm diameter for standard core holes
50 mm cutting depth for deep through-holes
Quick IN shank 18 mm for fast tool changes

Consistent hole quality through solid carbide engineering

The solid carbide design delivers rigidity and thermal stability that standard HSS cutters cannot match, resulting in precise, burr‑reduced holes even under heavy loads. With a 28 mm diameter and a 50 mm cutting depth, this core drill maintains concentricity over the full working length and reduces the need for secondary rework. The six cutting edges provide a steady cutting action and help distribute heat, which benefits throughput and extends tool life compared with softer tool grades.

Faster changeovers and secure clamping for uninterrupted productivity

The integrated Quick IN shank (18 mm) supports rapid insertion and positive locking in compatible toolholders, lowering spindle downtime during batch processing or tool swaps. The secure shank interface reduces run‑out and vibration, improving surface finish and repeatability on every workpiece. For workshop setups where minimal interruption and consistent part quality matter, this shank system shortens cycle times and simplifies machine logistics.

Built for tough applications: rails, wear steels and high‑alloy grades

The cutter is engineered for heavy‑duty applications including railroad rails, Hardox / Weldox 400 and other wear‑resistant steels, as well as high‑chrome grades (V2A, V4A), cast steel and general structural steels. The carbide composition tolerates elevated cutting forces and abrasive conditions, enabling operators to produce clean cores in materials that quickly blunt conventional drills. Choosing a carbide core drill for these tasks reduces tool change frequency and helps maintain production targets under harsh conditions.

FAQ

What materials is this core drill suitable for?
The Ruko core drill D.28 mm is suitable for a range of heavy materials including railway rails, Hardox / Weldox 400, various steels, cast steel and high‑chrome grades such as V2A and V4A.

Is the shank compatible with quick‑change holders?
Yes, the tool features a Quick IN shank (18 mm) designed for fast, secure insertion into compatible quick‑change systems.

How deep can this drill cut in a single operation?
The cutter offers a 50 mm cutting depth, allowing deep core holes without step drilling for many industrial applications.

How many cutting edges does the cutter have and why does that matter?
The drill has six cutting edges, which improve chip distribution, reduce cutting forces per edge and contribute to a smoother finish under heavy conditions.

Can this tool be used on stainless and high‑alloy steels?
Yes, the carbide composition and geometry make the drill suitable for stainless and high‑alloy steels, including V2A and V4A grades; suitability depends on machine power and machining parameters.
