Kreg KMA2400 Rip-Cut Circular Saw Guide

This classic rip guide from Kreg turns a standard sidewinder circular saw into a straight-line ripping machine. It locks onto a sturdy aluminum track, so your saw follows the edge like it’s on rails. For 2×4 work, it shines when you need long, straight rips or to split studs for custom dimensions. Setup is quick, and once calibrated, it repeats widths with confidence.

While the best circular saw jig for cutting 2×4 often focuses on crosscuts, I reach for the Rip-Cut when I need straight, long cuts on dimensional lumber. It pairs well with a framing blade for fast feed, and a fine-tooth blade for clean edges on finish studs. Check your saw’s shoe and guard clearance for fit, and you’re off to the races.

Pros:

• Excellent for straight, repeatable rips on 2x lumber
• Fast setup with adjustable scale for width
• Rigid guide helps tame knotty studs

• Compatibility varies with some worm-drive saws
• Requires initial calibration to your saw
