#M21 grey medium-soft vitrified 120 17.95
• This wheel dresses easily and removes material quickly. It doesn’t hold its shape as well as harder wheels, but It remains one of our best selling wheels.

#M21W grey waxed medium-soft vitrified 120 18.95
• This wheel is similar to the wheel above, but it is impregnated with wax for lubrication and cool grinding. Like the wheel above, it produces a good finish on cutter teeth, but it is not as popular.

#M47 salmon medium vitrified 100 17.95
• This wheel shapes and finishes cutter teeth well. It doesn’t remove material as fast as softer wheels above. It is also one of our best selling wheels.

#M50 white medium vitrified 100 17.95
• This wheel is similar to the wheel above. Some grinder operators say its white color makes it easier for them to see the corner in the wheel, which improves their ability to align corners.

#M49 brown medium resinoid 80 18.95
• This wheel removes material easily and quickly, however it doesn’t finish or shape as well as others. It is a good wheel if you have to grind a lot of chains each night or if you regularly sharpen rocked chains.

#M99 blue medium vitrified 100 39.95
• This is our only ceramic blend wheel. It keeps its shape and finishes cutter teeth very well. It is an excellent wheel and many grinder operators prefer it, but it is also the most expensive.
