At the beginning of the year we set out to create an extremely fast grinding wheel for carbon steel, stainless steel, and all alloys that also delivers quiet, chatter free grinding. By modifying our Sigma Green wheel and only using premium 24 grit grain, we were able to accomplish this goal. [Sigma Z outperforms most ceramic and engineered grains](https://www.rexcut.com/product/sigma-z) and will be available early 2021. Sigma Z optimizes production with exceptional metal removal rate, long life, and superior finish. Precision-balanced for noticeably smoother and quieter operation, it is truly operator friendly. ![sigma z fast grinding wheel for stainless steel](https://www.rexcut.com/hs-fs/hubfs/rex-cut_sigma_z_web.jpg?width=413&name=rex-cut_sigma_z_web.jpg) **Here is a look at this new fast grinding wheel** - 2x the stock removal rate as Sigma Max on stainless steel - Over 30% longer life than Sigma Max - Quiet, chatter free grinding - 100% Premium Grain in a proprietary bond - Out performs most ceramic and engineered grains "Rex-Cut's new Sigma Z Type 27 wheels raise the bar in the market for high performance grinding products designed for metal removal," states Bob Costa, President of Rex-Cut Abrasives.
