With the Dewalt DT3901-QZ planer blades, you achieve smooth and precise results across various woodworking projects. This pack of 2 carbide planer blades measures 80 MM and is engineered for compatible Dewalt planers including the DW676, DW677, DW678, and DW680. The durable tungsten carbide construction resists wear, providing long-lasting cutting performance through different types of wood. Thanks to the reversible two-edged design, you simply flip the blades around whenever one edge wears down, instantly restoring a fresh, sharp cut. This eliminates rough finishes and tear-out when leveling rough timber, trimming doors to size, chamfering edges, or cutting rebates.
