Makita GA4031 4″ Angle Grinder 720W (100mm) | Original

Experience precision cutting, weld blending, and surface deburring with the industry-standard Makita GA4031 4-Inch Angle Grinder. Renowned across workshops and industrial manufacturing sites for its high power-to-weight ratio, the GA4031 combines heavy-duty durability with an easy-to-grip, small-circumference barrel housing that gives you effortless one-handed control.

The tool features Makita’s proprietary labyrinth construction, an internal labyrinth seal system that blocks abrasive dust, swarf, and metal debris from penetrating the motor windings and ball bearings. Machined bevel gears deliver smooth power transfer and minimal vibration, while the exterior rear air vents keep internal temperatures low under prolonged site workloads.

Key Highlights

• Industrial 720W Motor: High-output copper motor engineered with advanced heat resistance to run cooler and maintain cutting cadence under steady load.

• Small-Diameter Barrel Grip: Ultra-compact circumference allows a firm, ergonomic hand grip, reducing fatigue during extended fabrication or overhead work.

• Labyrinth Dust-Proof Seal: Shields internal armature, field coils, and bearings from airborne masonry dust and conductive metal grit to extend service life.

• High-Torque Machined Gears: Spiral bevel gearing delivers quiet operation, higher torque density, and smooth energy transfer.

• Thumb Slide Switch: Body-mounted side slide switch with lock-on feature enables continuous cutting without finger fatigue.

• Push-Button Spindle Lock: Standard M10 spindle lock makes swapping cutoff discs, grinding wheels, and wire brushes quick and hassle-free.
