Sharpening Supplies and Accessories

Diamond Grinding wheels. All wheels are 100 % diamond concentration by volume

Side Grinding Wheel

Once you try a 5" diamond wheel for side grinding you will never go back to a 6" again. You will be surprised what a difference just 1" can make. The 5" wheel allows you to bring the tooth in closer to the motor shaft before the wheel starts to grind. This gives less flexibility, making side grinding easier with faster stock removal. Also this style of wheel allows you to side grind without interference of the motor shaft. This wheel is also great for carbide jointer and planer knives

Face and Top Grinding Wheel

Grinding wheels make the difference and good wheels are what determines the quality of your work. Use the proper grinding wheels in order to get a quality sharpening job.

Thin Rim

Needed for sharpening 10" diameter blades with 80 0r more teeth or a 12" with 100 or more teeth on the saw blade. The carbide tip usually comes real close to the steel backing of the tooth in front of it, which interferes with getting the wheel to go deep enough into the gullet to face the tooth, because of the standard wheel thickness. This wheel will illuminate that problem.
