General Tools' Digital Sliding T-Bevel is just what it sounds like: a bevel gauge with an electronic readout. When it's used with a miter saw with a digital readout, its numbers can be quickly transferred to the saw. The tool is accurate to within 3/10 degree and will also give the reverse – or joining – angle. It has an 8-inch stainless steel blade and an ABS handle. It's powered by a 3-volt lithium coin battery, but of course it can also be used to measure and transfer angles just like a standard T-bevel.
