This new thickness gage from Insize Tools is an accurate, very fast and easy to use tool for measuring neck wall thickness. You can make multiple thickness measurements around a case neck in just a few seconds to determine the neck uniformity, or easily calulate a needed neck bushing size without having a loaded round. The gage works with a spring loaded sliding anvil so the anvil pressure is always consistent, and comparing multiple measurements will be accurate. The ball anvil for case necks or tubing can be moved down to allow the gage to measure flat stock up to 1 inch thick. Accuracy on the digital display is 0.0005 inch, with controls for on/off, zero and inch/millimeter. Comes in a fitted plastic case and uses standard SR44/357 batteries(included).
