First-Cut, Early Entry Diamond Blade w/ Triangle Knockout - BASIC4000

Early entry saw operators cutting control joints in fresh concrete will find this blade delivers clean cuts during that critical 1-4 hour window after finishing. The BASIC4000 features a triangle knockout arbor design that adapts to multiple early entry saw models without requiring separate arbor hardware. Diamond Products engineered this blade specifically for green concrete applications where timing matters and you need reliable performance before the slab fully cures. The early entry design minimizes spalling and random cracking by cutting joints when the concrete is still workable but firm enough to support the saw. Built for flatwork contractors and saw crews running early entry equipment on commercial slabs, parking structures, and warehouse floors.
