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.
