Freud 99-036 Adjustable 1-3/4-Inch Tongue & Groove Bit Set

Precision joints with a trusted name

Freud's 99-036 adjustable tongue and groove bit set helps woodworkers achieve precise tongue and groove joints across a range of materials. The unique spacer system allows adjustments in 0.002 inch increments, supporting stock thickness from 1/2 inch to 1-1/4 inch and groove depths from 7/32 inch to 3/8 inch. The 1-3/4 inch diameter tongue bit and the matching groove bit work together to produce tight, consistent profiles while minimizing play and gaps.

What makes this set stand out

Opposing shear angles are engineered into the bits to reduce chipping and tear out on top and bottom surfaces, delivering a clean, finished edge right from the router. The bits are coated with Freud’s Silver ICE coating, which helps dissipate heat and reduce pitch buildup, supporting longer tool life and smoother cuts across multiple joints.

To maximize durability, Freud uses TiCo Hi-Density carbide, engineered specifically for each application. This combination of carbide and microstructure delivers improved wear resistance and consistent performance even after extended use. The set is designed for use with table-mounted portable routers, making it a solid choice for shop setups focused on cabinetry and panel work.
