Product Description
Engineered specifically for heavy-duty wall chasing, trenching, and joint cleaning. Produced via high-density hot-pressing sintering, this cost-effective wall slotting blade features protective half-round segments to shield the main teeth and four pin holes for exceptional balance. It delivers smooth, low-vibration operation across masonry, concrete, and stone surfaces.
Versatile Multi-Material Application
Suitable for chasing, cutting, grinding, and cleaning cement, concrete blocks, and bricks. Can also be occasionally used for processing natural stone such as granite and marble.
Protective Half-Round Segments Extend Blade Life
Features specialized half-round drop-segments on the steel core below the main teeth. This design prevents abrasive material build-up, shields the main segment roots from premature wear, and extends total working life.
Hot-Pressed Sintering Process for Cost Efficiency
Manufactured using hot-pressed sintering technology. Delivers high segment density and reliable performance while keeping production costs low, providing a highly competitive price-to-performance ratio.
Four Pin-Hole Design for Smooth, Balanced Operation
Equipped with four precision pin holes and a standard 230mm diameter with a 22.23mm arbor. Ensures secure, well-balanced mounting on a wall chaser machine, significantly reducing hand vibration and improving operator fatigue.
