AV-56 Stump Bit Grinder
Create your AV-56 stump bit sharpening machine. Choose the stump grinding tool fixture or fixtures below to fit your needs. The AV-56 stump bit grinder alone is the base machine. It does not include any tool fixtures or grinding wheels.
This AV-56 stump bit grinder will sharpen all the popular brands of stump grinder teeth. A majority of these teeth can be sharpened in less than two minutes per tooth. For easy alignment, the motor tilts when sharpening the straight, right and left-hand teeth for the standard stump bit tool fixture. The motor stays at the zero quadrant for the other three tool fixtures. The AV-56 sharpening machine includes: a 60 HZ – TEFC Leeson motor which runs at 3450 RPM, machine light, angle finder, written instructions, training DVD and customer service.
The Standard, Yellow Jacket and Sandvik tool fixtures include a special diamond 40 grit, plated radius grinding wheel. These plated grinding wheels match the contoured top radius of the tooth. Our plated wheels are a lot cleaner to use and require no wheel dressing like the green wheels from other suppliers. The diamond plating is also on the side of the wheel to sharpen the flat face of the teeth. For more pictures or information, please click one of the highlighted fixture links below.
The Green/Red tooth fixture includes a diamond, 180 grit bonded wheel. This grinding wheel is designed to sharpen the 500, 700, 900 and 1100 series teeth. There is 1/4″ depth of material for extended wheel life. For more pictures or information, please click the highlighted fixture link below.
Sharpening stump grinder teeth can be an excellent business of its own.
Add the AV-54 Automatic Knife grinding machine and sharpen chipper knives. Most companies operating a stump grinder will have a wood chipper as well. Have the availability to sharpen their chipper knives also for added income revenue.
