Freud 89-670 3 Piece Undersized Plywood Router Bit Set 1/2 Inch Shank 7/32 15/32 23/32 Inch Diameters with Wooden Case for Grooves and Dadoes

Seamless Joinery for Modern Materials: The Freud 89-670 Undersized Plywood Bit Set

The Freud 89-670 3-Piece Undersized Plywood Router Bit Set is the definitive solution for woodworkers and cabinet makers struggling with the loose joints caused by standard-sized bits. Modern plywood rarely measures its nominal 1/4", 1/2", or 3/4" thickness, often leaving unsightly gaps in grooves and dadoes. This specialized set features mortising bits precisely sized at 7/32", 15/32", and 23/32" to match the actual true thickness of today's undersized panels. Whether you are building high-end cabinetry in Tomball or custom shelving in your home shop, these bits ensure a tight, professional-grade fit every time, eliminating the need for shims or multiple passes.

Crafted with Freud’s legendary TiCo™ High-Density Carbide, each bit is engineered for industrial performance and longevity. The 1/2" shank provides maximum stability and reduced vibration when used in table-mounted or hand-held routers. To protect your investment, each bit features Freud’s signature red Perma-SHIELD® non-stick coating, which drastically reduces friction, prevents pitch buildup, and protects against corrosion. These bits effortlessly cut through hardwood, softwood, plywood, and composites, delivering a flawless finish. Housed in a premium wooden shadowbox case, this set is an essential upgrade for any craftsman who demands precision and structural integrity in their joinery.

Specifications

Pro-Tip: Before routing your final workpiece, always use a scrap piece of your project's plywood to test the fit. Plywood thicknesses can vary between batches; a quick test cut ensures the bit depth and width are perfectly dialed in for the tightest possible interlocking joint without forcing the material.
