Overview
The Kreg KMA4000-E Kreg Portable Circular Saw Crosscut Jig (Model KMA4000-E) is a circular saw crosscut guide designed for fast, accurate crosscutting on boards up to 8 inches wide. This is a saw accessory designed for guided crosscuts with a circular saw when you want miter-saw style accuracy without the bulk.
Set-up is simple: mark your cut, align the guide to your pencil line, and cut. Retractable cutline indicators show where the blade will cut, so you can line up quickly and get consistent results without guessing.
For stability, the GripMaxx anti-slip base helps prevent the jig from walking during the cut, and the saw support ledge helps keep the saw straight as you start the cut. That combination is what keeps this guide useful on a jobsite where you are working off sawhorses or a tailgate, not a perfect bench.
The jig is built to handle real use with rugged, impact resistant polymer construction. It is meant to be tossed in the truck and pulled out whenever you need quick crosscuts for framing lumber, shelving, or project parts.
Angle versatility is built in. Use it for accurate 90 degree cuts for square ends and 45 degree cuts for miters, all with your circular saw.
It is also adaptable across saw styles. The guide works with both left-blade and right-blade circular saws, so you do not have to buy a specific saw layout to use it.
