The Makita Wall Chaser (typically the SG1251J or SG150) is a precision engineered tool designed for cutting clean, narrow channels in masonry, brick, or concrete. It is a staple for electricians and plumbers installing conduit or pipework.
Core Features
Twin Blade System: Utilizes two diamond blades that can be adjusted for varying width and depth.
SJS (Super Joint System): Makita’s signature technology that prevents gear damage by absorbing shocks if the blade binds.
Dust Management: Features a built-in vacuum port, crucial for maintaining visibility and health when cutting dry stone.
Precision Control: An ergonomic handle and aluminum blade housing provide stability, while the soft-start motor prevents initial jarring.
