A good table saw comes with a perfectly good miter gauge. But this Incra is perfectly great. It’s precise, versatile, infinitely adjustable and custom-fits to your miter gauge slot.
You’re probably familiar with the Incra name because of their fantastic dovetail and box-joint-making jigs, but they’ve got a wide product line all with precision at the top of the list.
An ingenious flip-stop locks down at any point along the fence for repeatable cuts, and it flips out of the way without disturbing your placement if you have other cuts to make as well. The fence actually telescopes out, from a closed length of 18 inches to a fully extended 30 inches for superior stock stability. The miter gauge itself has 41 detents in 5-degree increments across the entire 180 degrees, with special stops at 22-1/2 and 67-1/2 degrees, all gauged by angle indexing teeth for unparalleled accuracy. In addition, you can make 1/10th-degree adjustments with the stainless steel vernier cursor.
The thing we like best about this jig is its ability to custom fit to your miter gauge groove, courtesy of six disks along the length of the slot bar. With a turn of an allen wrench, each one expands or contracts individually to get you the absolute best fit on your table, leaving you with zero play between bar and channel and zero chance for error. Incra’s also designed a neat top-mounted tab that fits a T-slot and removes in a few second for plain channels, letting you move the jig from your T-slotted table saw to other tools with a standard groove, such as a router table.
