Thickness gages (often called ""feeler gages"") provide reloaders with an easy way to set up neck turning tools to a desire cut thickness. They can also be useful wherever a known standard thickness example is needed. This American Made set has 26 gages from .0015"" to .025"". The gage leaves are tapered for easier use and fold into the protective handle. All leaves are laser marked with the size in thousandths.
