Angle Grinder Hitachi G 13SR4

The Angle Grinder Hitachi G 13SR4 is a compact hand-held grinding and cutting tool powered by a 730 W motor with a maximum no-load speed of 10,000 RPM. Designed for general metal and construction work, this model accepts a 125 mm (12.5 cm) grinding disc and uses an M14 spindle thread for accessory mounting. With a net weight of 1.8 kg and a low overall height of 63 mm, the tool offers comfortable handling and access in tighter workspaces. Its robust black and green housing provides durability for routine workshop and on-site tasks.

Advantages

The grinder’s 730 W motor delivers steady power for common grinding, deburring and cutting operations while the 10,000 RPM maximum speed supports efficient material removal. The compact height and relatively low weight reduce operator fatigue and improve maneuverability when working in confined areas. The M14 spindle thread ensures compatibility with a wide range of 125 mm discs and accessories. The durable exterior construction contributes to longer service life under regular use.

How to use

Fit a compatible 125 mm disc onto the M14 spindle and securely fasten the disc according to the accessory manufacturer’s instructions. Hold the tool with both hands, one on the rear handle and the other on the auxiliary handle or barrel, to maintain control. Start the grinder at no-load and allow it to reach full speed before engaging the workpiece. Use smooth, consistent strokes and avoid applying excessive pressure; let the disc perform the cutting or grinding. After use, switch off the tool and wait for the disc to stop completely before setting the grinder down or changing accessories.

Usage recommendations

Use appropriate personal protective equipment such as eye and hearing protection, gloves and a dust mask. Select the correct disc type and grit for the material and task. Ensure the workpiece is secured and inspect discs for damage before use. Allow periodic cooling breaks during heavy or extended operation to protect the motor and prolong tool life.
