First-Cut, Early Entry Diamond Blade w/ Triangle Knockout - EXPERT4000

Early entry saw operators cutting control joints within two to four hours of concrete finishing will find this diamond blade designed specifically for green concrete applications. The EXPERT4000 features a triangle knockout arbor configuration that fits multiple early entry saw models without adapter plates. The blade's segment design handles the abrasive paste of fresh concrete while minimizing spalling at the joint edges. Early entry cutting reduces random cracking by creating control joints before internal stresses develop in the slab. The knockout arbor system allows quick blade changes between jobs without carrying multiple arbor sizes. This blade works in both wet and dry cutting conditions depending on your saw setup and job requirements. Built for concrete contractors and flatwork crews running early entry saws on commercial floors, parking structures, and industrial slabs.
