The Makita M9513B is a high-performance, 850 W corded angle grinder engineered for demanding metal‑working and cutting tasks. It spins a 100 mm (4″) grinding wheel at an impressive 11,000 RPM, offering fast, efficient material removal suitable for heavy-duty use. This model features precision machined bevel gears and spiral‑bevel gearing that enhance torque transfer and durability for long service life. Despite its power, the grinder remains lightweight at just 1.8 kg (4.0 lbs.) and is designed compactly (dimensions: 273 × 118 × 101 mm) to minimize operator fatigue. Operator-friendly features include a toggle switch for intuitive on/off control, a shaft-lock mechanism for easy wheel changes, and fully double‑insulated construction to enhance safety in indoor or outdoor use. The wheel cover is engineered to offer protective clearance should a wheel fragment, enhancing operator safety. Additionally, the side handle can be mounted on either side of the tool for better balance and control.
