Review on 🔧 HFS Precision Hardened Blocks Without by Todd Phillips

Great value for money. We need them to calibrate the paper cutter - our tolerance is in the range of 0.1-0.5mm. For our purposes, this set works absolutely perfectly. There's no noticeable difference between them, but we haven't measured them. They came in an odd spaceline which we ridiculously took off so they were clean and ready to use within minutes of delivery and were well protected during the shipping process. Would buy again.
