Kraft Tool CF374PF 8 Inch Bronze Deep Bit Concrete Groover 1 Inch Depth 1/4 Radius Control Joint Finisher ProForm Grip

Establish Deep Control Joints with Heavy-Duty Bronze Precision

Create precise, durable control joints in your concrete flatwork with the Kraft Tool CF374PF Bronze Deep Bit Groover. This professional-grade tool is cast from 100% solid bronze, offering a significant advantage over steel or zinc alternatives. The natural weight of bronze helps the tool sit firmly in the concrete, allowing it to cut through tough aggregate and stiff mixes with minimal downward pressure from the user. Designed for projects requiring substantial stress relief, this groover features a 1 inch deep bit, making it the ideal choice for 4-inch slabs and other standard pavements. The bit creates a 1/2-inch wide groove with a smooth 1/4-inch radius, ensuring edges that resist chipping and spalling over time.

Efficiency and comfort are built into every inch of this 8-inch long tool. The blade is hand-polished to a mirror finish, allowing it to glide effortlessly across the surface without dragging or snagging. Its "closed bit" design prevents concrete buildup inside the tool, ensuring a continuous, clean cut. To keep you working comfortably all day, the groover is fitted with Kraft’s signature ProForm® soft grip handle. This high-visibility orange handle features textured ribbing that wicks away moisture and provides a secure, non-slip grip, significantly reducing hand fatigue during extended finishing sessions on hard materials like pervious concrete.

Specifications

Pro-Tip: The general rule for control joints is that they should be at least 1/4 of the slab's total thickness. With a 1-inch cutting depth, this groover is perfectly suited for standard 4-inch concrete slabs, such as sidewalks and residential driveways. Always ensure you match your tool depth to the slab thickness to prevent uncontrolled random cracking.
