Tool Grinding Air Bearing, Great for Krest-Kuts and Wave Cuts

Description

Grind almost any size end mill or cutter, carbide or steel. Great for Krest-Kuts and Wave Cuts.  Tool Grinding Air Bearing, Professional Instrument, # 50 Taper Air Bearings. Designed to hold a #50 Taper End Mill holder. Included is the base, the air bearing, valve assembly and draw bar. One unit has an index ring mounted to the front of the bearing the other does not. These are 95 each. The 2" End Mill and the # 50 Taper End Mill holder are not included. ( #50 Taper end mill holders come in sizes from 3/8" up to 2-1/2" shank capacity.) We have three of these air bearings. The only bearing that has any manufacturer's information on it is the one we have on one of our grinders. I'm thinking the one with the information is the oldest bearing. There are no markings on the other two but, there is a shiny area where there appears to have been a placard on one. Let me know which one of the three you would like. We will be keeping one for our own use. Any of the other two are for sale. They all work equally well.

Take a look at the accuracy on the ID of the air bearing. https://www.youtube.com/watch?v=CNJIAY9PdXU https://www.youtube.com/watch?v=Xdf4w6o97h0
