SagaSave 6 Pcs Telescoping Gage Set, 8-150mm Adjustable Inner Diameter Gauge Micrometer Measuring Tool for Wood, Metal Processing

Features:【High Quality】The surface of the telescopic rod is smooth and the probe curvature is good. The contact points are hardened tool steel. The tail gauge radius is precision ground along with a locking device to allow proper clearance on the smallest hole the gauge will enter.【Self-centering Function】The diamond non-slip double-action rigid handle is attached to the contact plunger and has a self-centering function for quick inspection of holes, slots and grooves up to 6 inches deep for adjustment to achieve accurate measurements.【Spring Tension】The two spring-tensioned telescopic plungers of the slide gauge has constant tension and can provide even contact pressure.【Operation Method】The measuring wheel is easy to operate. First squeeze its inner diameter ruler, put it into the object to be measured (in the hole or groove), then rotate it once to ensure that there is no skew, then after the measurement is correct, tighten the lock clockwise, and finally lock it, and use a caliper to measure the inner diameter data.【Wide Application】The six-piece telescopic gauge kit is suitable for measuring deep and shallow holes and grooves, and uaually used in wood, metal processing, machining and other fields.Specification:Material: SteelColor: SilverMeasuring Range: 8-150mm / 0.31-1.91"Package Included:6 PCS*/Set Measuring Tool
