Craigh9916 Posted July 22, 2016 Report Share Posted July 22, 2016 Has anyone used one of these new Milwaukee steelhead blades ? If so are they good or have they not been released yet as I just watched a video on you tube but they didn't demo it so want some feedback ?

Stercorarius Posted July 22, 2016 Report Share Posted July 22, 2016 I am also interested. Are these only available for chop saws or 4.5"/6" angle grinders as well? Quote Link to comment Share on other sites More sharing options...

Well I watched the recent cop tool video and they are available from 4 inch upwards and this is what interested me as I want one for my 4 1/2 inch grinder Sent from my iPhone using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...
Logan Posted July 22, 2016 Report Share Posted July 22, 2016 Haven't used one but they look pretty cool I wonder how the will perform Quote Link to comment Share on other sites More sharing options...
jeffmcmillan Posted July 22, 2016 Report Share Posted July 22, 2016 Typically you don't use diamonds on ferrous metals because the diamonds, particularly the cutting edge, slowly dissolve into the metal. So did they just stick more diamonds on and deal with the decreased cutting performance since it's still better than aluminum oxide, or is this actually CBN sold as diamond for marketing purposes. I'm really hoping it's CBN cause more people need to use that. 1 Quote Link to comment Share on other sites More sharing options...

Hasn't seemed any different from other grinding methods. It's just a matter of grit large enough to reduce loading. Quote Link to comment Share on other sites More sharing options...
