Stainless Steel Shot
Stainless Steel Shot is convenient to store as it will not rust. Our mixture is designed for the best finish on a wide variety of pieces.
Deburring Powder
A metal cleaning compound when mixed with water will keep the deburring media clean and active. This helps to increase the life of the media to provide the maximum effect during the deburring operation. This powder can also be used to inhibit rust formation when deburring steel parts. Easy to use (by dissolving 4 ounces per gallon of water) or can be added directly to the load.
Burnishing Soap
The ideal additive that gives workpieces the proper burnished look. The soap works by lubricating the parts and also provides protection against rust and tarnish formation. Comes in powder form and is dissolved 4 ounces per gallon. Can be added periodically to flow-thru systems.
Graves TumbleDry Metal Polishing Media
The preferred media for metal polishing. The walnut shells are precoated with a buffing flour, bonding agent and is available with either a red or green rouge to impart a luster to the polished workpiece. Choice of the rouge is dependant on the type of metal being processed. Select the proper one for your application. Tumble Dry is also available in a clear formula which contains a waxy compound bonded to a soft media giving workpieces a very high luster. It is can be used on all metals, stones or organics for final finishing and protection against tarnishing.
