Product Spotlight: Mahr MarCal 30 EWRi-N Digital Depth Gage IP67 Wireless for Groove measurement

Depth gages are extremely useful hand tools designed to inspect the depth of counterbores, slots, recesses, holes, among others. These tools are widely used by professionals in the tool and die industry. In the past, workers were limited to mechanical scales. In fact, earlier versions of gages comprised a simple rule and a sliding perpendicular beam, which served as the reference. You had to set the scale into the hole you were measuring, and with the slide squared up with the reference surface. The operator had to apply proper technique and employ good judgement. Without those, errors could occur.
