Annular cutter Ø40 mm – solid carbide, 50 mm cutting depth (Ruko)

The Annular cutter Ø40 mm is a heavy‑duty core drill designed for efficient through‑hole cutting in rails and high‑strength steels, supplied with a Quick IN 18 mm shank for rapid tool changes

• Solid carbide construction for high wear resistance
• 50 mm cutting depth for deep boreholes
• Quick IN 18 mm shank for fast tool changes
• Designed for rails and high-strength steels

High‑performance construction for consistent hole quality

The annular cutter is made from solid carbide, offering elevated hardness and thermal stability that prolongs tool life under demanding conditions. The geometry with 8 cutting edges ensures smooth chip formation and reduced radial forces, which produces clean, burr‑reduced boreholes in one pass. This construction translates directly into fewer tool changes and lower rework rates, helping to keep machining cycles predictable and efficient. The combination of carbide body and optimised cutting geometry supports repeatable accuracy on heavy parts where hole integrity is critical.

Faster setup and less downtime with Quick IN

Equipped with a Quick IN 18 mm shank, the cutter permits rapid clamping and interchange in systems that accept the Quick IN interface, reducing non‑productive time during tool changes. The shank design contributes to secure axial transmission and concentricity, which helps maintain hole precision even when working on stacked plates or uneven workpiece surfaces. Reduced setup time and reliable tool retention enhance throughput in fabrication shops and maintenance operations where speed and repeatability are essential.

Suited to demanding materials and industrial applications

The cutter is intended for applications such as railway rails, Hardox/Weldox 400 and other wear‑resistant steels, general steel and cast steel, plus high‑chromium and highly alloyed stainless steels (V2A, V4A). This material scope makes the tool suitable for heavy fabrication, repair work, and structural applications where conventional drills wear quickly. Using a purpose‑built annular cutter reduces heat build‑up and the need for multiple drilling stages, delivering reliable performance on challenging substrates.

Practical performance, handling and best practice

With a 50 mm cutting depth and an overall length of 112 mm, the cutter is dimensioned for substantial through‑hole work without compromising rigidity. For best results, use appropriate cutting fluid and moderate feed rates to support chip evacuation and tool life; the solid‑carbide design benefits from controlled cutting conditions rather than aggressive plunge feeds. Supplied as single units, these cutters are straightforward to stock for targeted maintenance or production tasks and integrate well into workflows that favour durability and precision.

FAQ

What materials can this annular cutter machine?
The annular cutter is designed for heavy materials including railway rails, Hardox/Weldox 400, general steel and cast steel, and high‑chromium stainless steels such as V2A and V4A; its solid‑carbide construction supports these demanding applications.

Is the Quick IN shank compatible with magnetic drilling machines?
Compatibility depends on the machine’s chuck or arbor system; the Quick IN 18 mm shank fits magnetic drills and arbors that accept an 18 mm Quick IN interface—verify the machine interface before use.

How deep can the cutter drill in a single pass?
The tool provides a 50 mm cutting depth, enabling substantial through‑hole work without intermediate operations when used with appropriate feeds and coolant.

How many cutting edges does the tool have and why does that matter?
The cutter features 8 cutting edges, which improve chip control and reduce cutting forces, helping to produce cleaner holes and extend tool life under tough conditions.

What is the article number for ordering reference?
Order reference: 4000602648NW, listed as the Ruko annular cutter Ø40 mm with Quick IN 18 mm shank.
