Kraft Tool Concrete Groover CF305PF 6 Inch Bronze Hand Tool (1/4 Inch Radius 3/4 Inch Deep Narrow Bit Control Joint Finisher ProForm Grip)

Kraft Tool 6 Inch Bronze Narrow Bit Concrete Hand Groover

The Kraft Tool CF305PF 6-Inch Bronze Narrow Bit Concrete Hand Groover is a heavy-duty masonry finishing tool engineered to cut precise control joints in fresh concrete slabs. Cast from 100 percent solid bronze, this hand groover forms a 3/8-inch wide by 3/4-inch deep stress-relief groove with a 1/4-inch edge radius to manage thermal expansion and prevent uncontrolled surface cracking.

Best Used For:

• Sidewalk and Driveway Expansion Joints: Cutting 3/4-inch deep stress-relief control joints across newly poured residential concrete slabs.
• Stiff Mix and Pervious Slab Finishing: Slicing through stiff or low-slump concrete mixes using the low-resistance narrow bit design.
• Spall-Resistant Joint Profiling: Forming smooth 1/4-inch radius rounded edges along groove lines to protect joints from chipping under wheeled traffic.

Key Performance & Safety Features

• Solid Bronze Casting: One-piece 100 percent bronze body provides dense weight and superior wear resistance compared to steel groovers.
• Low-Resistance Narrow Bit: Extended narrow bit profile glides through wet concrete without snagging or dragging aggregate.
• Turned-Up Blade Ends: Hand-polished blade surface and turned-up end geometry prevent gouging into the slab face during bidirectional passes.
• ProForm Soft Grip Handle: Textured ribbing on the ergonomic orange handle reduces operator hand fatigue and improves traction when wet.

What's Included

• (1) Kraft Tool 6" x 4-1/2" Bronze Narrow Bit Groover (CF305PF)

Technical Specifications

Pro-Tip: Use a straight-edge wooden chalk line board to guide your first pass, allowing the bronze weight to set the 3/4-inch bit depth cleanly without disturbing adjacent surface paste.
