The Freud 1-3/4" (Diameter) Adjustable Tongue and Groove Bit Set is a precision-engineered router bit set designed for woodworkers who need flawless tongue and groove joints across a range of material thicknesses. Engineered in Italy and built around a patented adjustable spacer system, this set is the go-to solution for Shaker-style cabinet door construction, solid wood panels, and any joinery project demanding tight-fitting, chip-free results. With a 1/2" shank and a maximum operating speed of 16,000 RPM, this set is purpose-built for use in table-mounted routers, delivering professional-grade performance in shop environments where consistency and surface quality are non-negotiable.

Key Features

• Adjustable at.002" increments for stock thickness of 1/2" to 1-1/4" and groove widths of 7/32" to 3/8" - gives woodworkers precise control over joint fit without needing multiple bit sets for different material thicknesses
• Opposing shear angles eliminate chipping and tear out on top and bottom surfaces - means cleaner, ready-to-glue faces even on figured hardwoods, veneered plywood, and composites that are prone to surface damage
• Cuts all composition materials, plywoods, hardwoods, and softwoods - makes this a single versatile set suitable for a wide range of cabinet, furniture, and millwork applications
• Each bit is coated in Silver I.C.E. - a revolutionary coating that minimizes heat and pitch build-up - extending cutting performance and reducing the frequency of cleaning between cuts on resinous or adhesive-heavy materials
• Features TiCo Hi-Density carbide for longer bit life and flawless finish - delivers a higher quality edge retention compared to standard carbide, meaning more cuts per sharpening cycle and consistently smooth joint surfaces
• 1/2" shank diameter - provides maximum stability and reduced vibration when used in table-mounted router applications, contributing to more accurate and repeatable cuts

Why This Product

• The patented spacer system adjusting at.002" increments lets you dial in a perfectly snug tongue and groove joint for any stock from 1/2" to 1-1/4" thick - eliminating the guesswork and repeated test cuts that come with fixed-width bit sets
• Opposing shear angle cutters address one of the most common frustrations in groove routing - chipping on the top and bottom face of the workpiece - making this set a reliable choice for finish-critical work like veneered plywood cabinet doors and hardwood panels
• The combination of Silver I.C.E. coating and TiCo Hi-Density carbide means the bits stay sharper longer and run cooler, reducing downtime for cleaning and sharpening during high-volume production or extended shop sessions
• Designed specifically for table-mounted router use, this set integrates smoothly into standard shop setups, making it a practical upgrade for any woodworker building Shaker-style doors, frame and panel assemblies, or precision joinery in hardwoods, softwoods, or composite sheet goods

Frequently Asked Questions

What range of material thicknesses can this bit set handle?

The adjustable spacer system accommodates stock from 1/2" to 1-1/4" thick, with groove depth adjustments from 7/32" to 3/8". Fine-tuning is possible at.002" increments, giving you precise control over joint fit for a wide range of solid wood and panel materials.

Can this set be used with a handheld router?

No. This set is designed specifically for use in table-mounted routers. Using it in a handheld router configuration is not recommended, as table mounting provides the stability needed for safe and accurate operation at up to 16,000 RPM.

What materials can the Freud 99-036 cut?

This set is rated to cut veneered plywood, hardwoods, softwoods, and composites. The opposing shear angle design helps prevent chipping and tear out on the top and bottom faces of all these material types, making it suitable for finish-critical applications.

What technologies help extend the life of these bits?

Each bit features two key technologies: Silver I.C.E. coating, which minimizes heat and pitch build-up during cutting, and TiCo Hi-Density carbide, which provides longer bit life and a consistently flawless finished surface over extended use.
