TGP001 -- Tumbler grit and polish kit. consists of 1 lb. each: 60/90, 120/220 and 3f - 400 grit, tumbler polish powder and 12 oz. "Old Miser" grit carrier.
Shipping weight 6 lbs. 
$ 22.90   


Covington's® "Old Miser" is designed to help hold the grit in place. It holds the grit in suspension so that all the rocks are always covered with grit for faster grinding. "Old Miser" doesn't allow the water to wash the grit to the bottom and off the rocks. Covington's® "Old Miser" saves you time and money. 

 

For Faster Lapping, Tumbling & Sphere Cutting
Holds grit to your work so that it is not thrown off by centrifugal force or washed away by the small amount of water used in your work. However, it is water soluble and washes off the specimen easily, Pays for its cost many times over in grit and time saved.
