I just ordered a 1200 grit 6" diamond wheel from Enco,because I had been wanting to,and got their new catalog today. I saw that they had discontinued the type wheels I wanted. The machine I wanted them for is a horizontal/vertical diamond grinder that is 200 RPM. It is made by Sunnen,but is essentially the same as an Accu Sharp(is that the correct name?) The wheels are 6" diameter,with a small flat head screw in their centers. The flat side of the wheel is diamond plated.
They still had some in stock,so I had to act.
Anyhow,I got a wheel for the same price as last year,$142.00. Got 10% off my first order of the year over $50.00 from Enco.
P.S.: I just looked at my new 2012 Enco catalog,and a 6" Baldor style wheel with 1" wide diamond plated face is only $12.00 more than last year. What diamond wheels in particular have doubled in price? I don't think $12.00 is hurting us too much.
