Kraft Tool Concrete Groover CF317PF 7 1/2 Inch Bronze Hand Tool (1/4 Inch Radius 1 1/2 Inch Deep Bit Control Joint Finisher ProForm Grip)

Kraft Tool 7.5 Inch Bronze Deep Bit Concrete Hand Groover

The Kraft Tool CF317PF 7-1/2-Inch Bronze Deep Bit Concrete Hand Groover is a heavy-duty masonry finishing tool engineered to cut extra-deep control joints in thick structural slabs. Cast from 100 percent solid bronze, this specialized groover forms a 1/2-inch wide by 1.5-inch deep stress-relief groove with a 1/4-inch edge radius to satisfy commercial paving standards and prevent uncontrolled slab cracking.

Best Used For:

• Thick Industrial Slab Paving: Slicing 1.5-inch deep expansion control joints across heavy-load warehouse floors and commercial driveways.
• Pervious Concrete Slab Finishing: Slicing through stiff or low-slump concrete mixes using the low-resistance extended bit geometry.
• Spall-Resistant Joint Profiling: Shaping rounded 1/4-inch radius joint edges to protect concrete seams from chipping under heavy vehicle traffic.

Key Performance & Safety Features

• Solid Bronze Casting: One-piece 100 percent bronze body provides dense weight and superior wear resistance compared to zinc or steel groovers.
• Deep Cut Capacity: Slices a 1.5-inch deep groove into fresh concrete to manage internal stress in thick structural slab pours.
• 7-1/2-Inch Blade Profile: Extended 7.5-inch length delivers enhanced tracking stability and covers more slab 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: Align the groover along a straight wooden guide board on your initial pass so the 7.5-inch bronze base plate maintains a straight tracking line without riding over aggregate.
