The Stuart Batty Angle Gauge is used to set the angle of the tool rest on bench grinders, so the question should be what would the angle gauge do for the SVD-110 that the Tormek Angle Master cannot. I guess the answer is quicker and more consistent angle measurement. Glenn Lucas sells a similar gauge that he calls Moby Jig, which is made of plastic, instead of metal. The plastic body made it easier for me to adjust the contact points to get a more accurate angle with the Tormek 10" wheels.
