DEWALT Stacked Dado Saw Blade DW812DADO – 8-Inch 12-Tooth for Precise Grooves

Overview

The DEWALT Stacked Dado Saw Blade DW812DADO is engineered for woodworkers who value accuracy and repeatable results. With an 8-inch diameter and 12 teeth, it’s designed to cut grooves from 1/4 to 7/8 inches, ideal for dado joints, cabinet work, and shelving projects. The combination of durable materials and thoughtful design supports clean, dependable cuts across a range of common materials.

In this set you’ll find two outer blades, three chippers, three spacers, and seven shims. The teeth are oversize carbide and can be resharpened, while a heat-resistant, non-stick coating helps minimize buildup during longer sessions. Heavy gauge laser-cut plates contribute to true, stable cuts, and width adjustments stay precise thanks to the included shims.
