Ruko Solid Carbide Annular Cutter D 38 mm — 50 mm cutting depth, Quick IN shank

The Ruko Solid Carbide Annular Cutter D 38 mm is a high-performance core drill designed for fast, repeatable hole production in heavy-duty and stainless steels using a Quick IN 18 mm interface

• Solid carbide construction for high wear resistance
• 50 mm cutting depth for deep, efficient cuts
• Quick IN 18 mm shank for fast tool changes
• Six cutting edges for smooth hole finishing

Efficient holemaking for heavy-duty fabrication

The solid carbide construction delivers a clear advantage where durability and edge stability matter. As an annular cutter, the tool machines only the hole periphery, which reduces cutting forces compared with full-bore drilling and minimises material removed. The result is improved cycle times and extended tool life when working with demanding workpiece materials. With six cutting edges, the cutter produces a consistent bore with reduced vibration, meaning fewer corrective operations and a more predictable production flow.

Rapid changeovers with the Quick IN 18 mm shank

Equipped with a Quick IN shank (18 mm), the cutter supports fast clamping and removal in matching tool holders. This interface reduces machine downtime during tool swaps and simplifies setup in production and maintenance environments. For operations that alternate between multiple hole sizes or require frequent tool changes, the Quick IN system lowers non-productive time and contributes to smoother shift planning on the shopfloor.

Cleaner holes and less rework from precise cutting geometry

The peripheral cutting concept of an annular cutter yields a core rather than chips inside the hole, making subsequent handling of material easier. The combination of solid carbide tips and a well-defined cutting geometry delivers improved surface finish and hole cylindricity, which reduces the need for secondary finishing. For teams managing assembly tolerances, this translates into fewer rejects and a more stable quality output without complex machine adjustments.

Built for hard and stainless steels across industries

This cutter is specified for tough applications: railway rails, Hardox/Weldox 400 wear steels, structural steel, cast steel and high-chromium stainless steels (V2A, V4A). Such material compatibility makes the tool suitable for heavy fabrication, repair workshops and rail maintenance. Where corrosion-resistant or abrasion-resistant grades are common, the cutter’s carbide composition maintains edge integrity and helps preserve cutting performance across repeated cycles.

FAQ

What is the maximum cutting depth of this annular cutter?
The Ruko Solid Carbide Annular Cutter D 38 mm (SKU 4000602646NW) has a cutting depth of 50 mm, suitable for through-holes and deep bore requirements where a single-pass depth is required.

Which shank interface is required for this tool?
This tool uses a Quick IN shank with an 18 mm diameter; compatibility requires a Quick IN tool holder or adaptor that accepts an 18 mm interface.

What materials can be machined with this cutter?
The cutter is specified for railway rails, Hardox/Weldox 400, general steel and cast steel, and high-chromium stainless steels such as V2A and V4A, making it suitable for heavy fabrication and maintenance tasks.

How many cutting edges does the cutter have and what is the benefit?
The cutter features six cutting edges; this geometry promotes smoother cutting action and a superior bore finish, which helps reduce secondary machining and rework.

Can this cutter be used in maintenance and rail applications?
Yes, the design and carbide tips make the cutter appropriate for rail repair and heavy-duty maintenance where abrasion resistance and consistent hole quality are required.
