Angle Stops & Precision

Most miter gauges will have positive stops at common angles such as 45° and 90°. This ensures you are making precise cuts. Better miter gauges will have stops at more angles, and provide better precision.

The Kreg has stops at 0°, 10°, 22.5°, 30°, and 45° and can be set to other angles with 0.01° precision. The POWERTEC has stops every 5° between 0° and 60°, plus 22.5°.

Fence

A fence attached to the miter gauge’s head helps steady the workpiece for more precise cuts. It may also have a stop attached to make repeatable cuts of the same length.

The 71142 has a 7”-long fence.

Bar Style & Size

You want to choose a miter gauge that fits your table saw’s miter slots, both in size and shape. Most miter slots are 3/4” wide and 3/8” deep, though there are variations. They can be either rectangular slots (with straight sides and bottom) or T-slots (with small indentations along the bottom edge that keep a miter gauge from slipping out). You can use a rectangular miter gauge bar in a T-slot, but not vice versa, since the T-shaped protrusions won’t fit.

The bars on both products are 3/4” wide and 3/8” deep. The bar on the KMS7101 is 24” long. The bar on the 71142 is 17 3/4” long. Both miter gauges have a rectangular-shaped bar and come with an adapter for T-slots.
