Take advantage of the TiAlN hard-coating and HSS base material for longer tool life and consistent hole quality; the Weldon shank ensures secure clamping for heavy-duty cycles. Order the Ruko core drill directly via Metav Werkzeuge or consult our specialists for application-specific advice.

Ruko core drill D 18 mm HSS with TiAlN, 30 mm cutting depth (Weldon shank)

A Ruko core drill D 18 mm HSS TiAlN with Weldon shank, engineered for reliable, high-temperature-resistant drilling in alloyed and unalloyed steels and cast materials.

• TiAlN coating for high temperature resistance
• Suitable for alloyed and unalloyed steel
• Weldon shank 19.05 mm (3/4") for secure clamping
• Optimised for dry machining and extended tool life

Boosted uptime and consistent hole quality

The combination of HSS substrate and a TiAlN wear-protection layer delivers measurable production benefits: the coating raises surface hardness to roughly 3,000 HV and preserves cutting performance at elevated temperatures (hot hardness up to 900°C). For workshop managers these properties translate into longer tool life and fewer tool changes per shift, reducing machine downtime and improving throughput. The construction and hardening are aimed at maintaining roundness and dimensional stability across repetitive bore cycles, supporting a steady output in small-batch and series production.

Material range and machining conditions that work for industry

Designed for machining unalloyed and alloyed steels (rated for use up to 1,200 N/mm²), high-chromium stainless steels such as V2A/V4A, steel castings and tough brass, the cutter maintains cutting-edge stability under demanding conditions. The tool features five cutting edges, which improve chip control and produce cleaner bore walls compared with simpler geometries. Thanks to the Weldon shank (19.05 mm / 3/4"), clamping is secure in standard holders, making the tool compatible with common tooling systems and ideal for higher feed forces where slip must be avoided.

Practical workshop integration and operational advantages

Optimised for dry machining, this core drill reduces reliance on soluble coolant, lowering running costs and simplifying chip and fluid management at the bench. The tool’s combination of coating and geometry supports higher cutting speeds where appropriate, enabling a favourable cost-per-hole ratio in many production scenarios. For maintenance and stock planning, the compact overall length (63 mm) and clearly defined 30 mm cutting depth make tool holders and inventory management straightforward. Confidence in repeatability and supply reliability is backed by Metav Werkzeuge’s position as a precision partner for industry and trade, ensuring consistent availability and expert advice when adapting the tool to specific tasks.

FAQ

How deep can this core drill cut?
The specified cutting depth is 30 mm, which defines the maximum effective bore depth for the Ruko core drill (SKU 4000602395NW).

Is the TiAlN coating suitable for dry machining?
Yes, the TiAlN wear coating is designed for high thermal stability and supports dry machining, reducing the need for external cooling in many applications.

Which materials are recommended for this drill?
The tool is intended for unalloyed and alloyed steels up to 1,200 N/mm², high-chromium steels such as V2A/V4A, steel castings and tough brass, as specified for the Ruko core drill.

What shank interface is required?
A Weldon shank with a 19.05 mm (3/4") diameter is used for secure clamping; this ensures reliable seating in Weldon-compatible holders during heavier drilling operations.

How do the five cutting edges affect performance?
The five cutting edges improve chip control and bore finish, delivering smoother cutting action and helping to maintain hole accuracy across repeated cycles with the Ruko core drill.
