J. Walter Inc. introduces the Zip type 27 cut-off wheel. The raised hubs of these wheels are completely covered with a polished steel cap. This metal cap prevents the wheel from possibly exploding when an unprotected hub comes in contact with the work piece. Walter also introduces two new cutting wheels formulated specifically for stainless steel, the new Zip stainless type 27 and the Zip stainless type 1. Both are 3/64â?, .045â? and fast cutting on all types of non-ferrous metals. The wheels free of iron, sulfur, chlorine and other contaminating ingredients. These nuclear grade products provide extra cutting life for all applications.
