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

Early entry sawing on fresh concrete demands a blade that can handle the narrow cut window without damaging the slab. The EXPERT4000 from Diamond Products features a specialized triangle knockout arbor design that fits early entry saws for cutting control joints within 1-4 hours of finishing. This first-cut diamond blade delivers clean, straight joints in green concrete while minimizing spalling and random cracking. The early entry design reduces joint depth requirements compared to conventional sawing, saving time and extending blade life in abrasive concrete mixes. Built for flatwork contractors and sawcutting professionals who need reliable performance during that critical early cutting phase.
