The SG1251J Wall Chaser delivers reliable performance and clean grooves for electrical and plumbing installations. Featuring dual diamond saw blades, this tool allows for adjustable cutting widths (via spacer rings) and depths (up to 30 mm), with sawdust efficiently captured or vacuumed through a built-in port. Safety-enhancing features—such as double insulation, soft-start, constant-speed electronics, and vibration-mitigating SJS—help maintain tool integrity and operator control. It also boasts an ergonomic dual-handle design and easy-to-change blades with an aluminum case for hassle-free maintenance. Equipped with a 1,400 W motor and twin 125 mm diamond blades, it cuts grooves up to 30 mm deep and 6–30 mm wide at a no-load speed of 10,000 RPM. Features like soft start, constant speed control, and Makita’s SJS (Super Joint System) reduce start-up stress and vibration. Its compact form (350 mm long) and manageable weight (≈4.3–4.5 kg) provide excellent control in vertical and overhead work.
