AccusizeTools - 3/8" Cutoff Holder, Cut Off Tool, MGEHR06-2 - Not worth the money. I bought this tool for easy grooving and parting off of small workpieces. The Tool was centered on a Hardinge lathe and perpendicular to the workpiece. I made two trial grooves on a Β½" round bar with no problem. I tried to cut, the tool was bent in the cut and now it won't hold the cutting tip. Three cuts and a blowout. I contacted AccusizeTools through their website. No response. I would not recommend this tool.
