Kraft Tool Concrete Groover CF316PF 6 Inch Bronze Hand Tool (1/2 Inch Radius 1 Inch Deep Bit Control Joint Finisher ProForm Grip)

Kraft Tool 6 Inch Bronze Denver Jumbo Concrete Hand Groover

The Kraft Tool CF316PF 6-Inch Bronze Denver Jumbo Concrete Hand Groover is a heavy-duty masonry finishing hand tool engineered to cut large expansion control joints in thick concrete slabs. Cast from 100 percent solid bronze, this specialized groover forms a 1-1/4-inch wide by 1-inch deep stress-relief groove with a 1/2-inch edge radius to satisfy commercial paving codes and prevent slab cracking under heavy traffic loads.

Best Used For:

• Highway and Airport Paving: Slicing 1-inch deep stress-relief expansion joints across heavy-duty industrial concrete highways and runways.
• Industrial Warehouse Flooring: Forming 1-1/4-inch wide expansion joints in high-load commercial slab pours to manage thermal movement.
• Spall-Resistant Joint Profiling: Shaping broad 1/2-inch radius rounded edges along groove lines to protect concrete seams from breaking under heavy machinery wheels.

Key Performance & Safety Features

• Solid Bronze Casting: One-piece 100 percent bronze body provides dense natural weight and maximum abrasion resistance compared to steel alternatives.
• Denver Jumbo Bit Profile: Cuts a wide 1-1/4-inch by 1-inch deep groove into fresh concrete to manage internal stress in thick structural pours.
• Turned-Up Edge Geometry: Hand-polished blade surface with turned-up ends glides smoothly without gouging the wet slab face.
• ProForm Soft Grip Handle: Textured orange rubber handle absorbs hand vibration, wicks away moisture, and provides non-slip control.
