CMT changed the way this tip was made and now it doesn't cut like the previous version that I have used for the past 13 years with no problems I don't understand why CMT felt the need to change the tip geometry. It took me several hours to program a new CNC just to adapt to this unnecessary change. I was furious when CMT stopped selling at my local Blade and Bit went out of business and now they have Will they change back Stupid move if you ask me.
