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

Early entry sawing on fresh concrete demands a blade that cuts clean before the slab fully cures, and this first-cut diamond blade delivers exactly that. The EXPERT4000 features a triangle knockout arbor configuration that fits specialized early entry saws used for cutting control joints within 1-4 hours after finishing. This design reduces random cracking by creating stress relief joints while the concrete is still green. The diamond segment pattern handles the abrasive paste that comes with cutting uncured material, maintaining depth consistency across long joint runs. Works on both residential flatwork and commercial floor pours where joint placement timing is critical. Built for concrete contractors and flatwork specialists running early entry saw systems on time-sensitive pours.
