Repair Valve Boxes – Faster, Better, and Less Expensive

We are developing a new version of this tool with some great improvements, and the current version is no longer available. Please sign up below to be notified when the new version is available.

Kerf Cutter makes repairing broken valve boxes quick, easy and long lasting.  No longer is there a need to bring in costly and dangerous heavy equipment to cut asphalt, dig out the broken section of the road and patch the pavement only to see the road settle months later and having to fix it again next year.

Kerf Cutter is the latest innovation for municipal water and street departments to fix broken valve boxes.

Kerf Cutter is a handheld, electric tool with a circular blade on the end. It is inserted into the valve box and cuts off the top of the valve box. Once that is removed, a new top can be inserted and leveled with the pavement.

Patent No. 9599271
