We have been trialing a new brand of grinder heads with our machines over the past week and we hardly needed a week with them because after the first day all the guys in my crew were raving about how much better they were to work with. I wanted to give them a week to make sure that they continued to do the job and didn’t break on us and they performed brilliantly all week. We have now been using them full time with our machines and I am already noticing an increase in turnover because we have been able to get through three extra jobs than we do in a regular week.
