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

Kraft Tool 8 Inch Bronze Deep Bit Concrete Hand Groover

The Kraft Tool CF374PF 8-Inch Bronze Deep Bit Concrete Hand Groover is a heavy-duty masonry finishing hand tool engineered to cut precise expansion control joints in fresh concrete slabs. Cast from 100 percent solid bronze, this specialized groover forms a 1/2-inch wide by 1-inch deep stress-relief groove with a 1/4-inch edge radius to satisfy standard 4-inch slab paving codes and prevent uncontrolled cracking.

Best Used For:

• Standard 4-Inch Slab Paving: Slicing 1-inch deep stress-relief control joints across 4-inch concrete driveways, walkways, and patios.
• Pervious Concrete Slab Finishing: Cutting through stiff concrete mixes or pervious slabs with reduced resistance using the extended deep bit design.
• Spall-Resistant Joint Profiling: Shaping rounded 1/4-inch radius joint edges to protect concrete seams from chipping under vehicle traffic.

Key Performance & Safety Features

• Solid Bronze Casting: One-piece 100 percent bronze body provides dense natural weight and maximum abrasion resistance compared to steel groovers.
• Deep Cut Capacity: Slices a 1/2-inch wide by 1-inch deep groove into fresh concrete to manage internal slab stress in 4-inch pours.
• 8-Inch Extended Base: Long 8-inch blade length delivers enhanced tracking stability and covers more surface area per pass.
• ProForm Soft Grip Handle: Textured orange rubber handle absorbs hand vibration, wicks away moisture, and provides non-slip control.

Technical Specifications

Pro-Tip: Guide the groover along a straight wooden chalk line board on your initial pass so the bronze weight sets the 1-inch bit depth cleanly without riding over coarse aggregate.
