The Ralli Wolf Mega 150 is a top-of-the-range 150mm magnetic core drilling machine engineered for the most demanding heavy-duty structural and industrial drilling applications. Built on 60+ years of Ralli Wolf manufacturing expertise, this powerhouse machine is driven by a massive 3080W motor with variable and reversible speed control across 4 speed settings (40–720 RPM), delivering the power and flexibility needed for large-scale core drilling, twist drilling, and tapping work.

Its heavy-duty electromagnet produces an outstanding 24,500N (2498.3 Kgf) of magnetic adhesion, ensuring rock-solid stability on ferrous surfaces even under extreme cutting loads. Fitted with an MT4 adaptor, a substantial 360mm stroke, twist drill capacity of 57mm, and tapping capacity of M50, the Mega 150 is purpose-built for large-diameter core drilling up to 150mm using the included MT4 core drilling adaptors (19.05mm and 31.75mm).

At 32 Kg (without accessories), the Mega 150 is a serious industrial machine designed for stability, power, and precision on the largest structural jobs — including shipbuilding, bridge construction, heavy plant fabrication, and infrastructure projects. It comes with a comprehensive accessory package including 3 side arms, M2/M3/M4 wrenches, a drift, coolant bottle, pilot pins, safety belt, and dual MT4 core drilling adaptors, giving operators everything needed for demanding site work.

Manufactured to ISO 9001:2015 quality standards, the Ralli Wolf Mega 150 is the go-to choice for professionals who need maximum power, capacity, and reliability in a magnetic drilling machine.
