Frequently Asked Questions

What is the difference between a finger joint and a box joint router bit?

A finger joint produces interlocking rectangular pins for edge-to-edge or end-grain connections primarily in structural applications. A box joint uses the same square-pin geometry for corner connections in box and drawer construction. Both the Finger Joint Router Bit (61/500) and Box Joint Router Bit (61/501) are stocked at Infinity Tools.

What shank size do the Infinity Tools joinery router bits use?

The primary joinery bits in this collection use 1/2 shanks, which provide greater mass and rigidity than 1/4 shank bits—important for the heavy cuts involved in most joinery profiles. Confirm your router's collet size before ordering.

Can the tongue-and-groove bit handle different stock thicknesses?

The 1/2" Shank Tongue & Groove Bit (61/510) is designed for stock between 3/8" and 5/8" thick. Check individual product pages for specific cutting range details before purchasing.

What does the drop leaf table router bit set produce?

The Drop Leaf Table Router Bit Set machines a matched rule joint—a concave cove on one piece and a convex roundover on the mating piece—allowing a table leaf to fold down while the joint edge remains visually clean.

What is included in the 7-piece rabbeting router bit combo kit?

The Infinity Tools 7-Piece Rabbeting Router Bit Combo Kit includes a rabbeting bit body and a set of interchangeable bearing sizes, allowing you to cut rabbets of multiple widths without changing bits.

Is a dovetail router bit used for hand-cut style dovetails or router jig dovetails?

The Infinity Tools Dovetail Router Bits are used with a dovetail jig or a router table fence to cut the angled dovetail pin shape. They are not used freehand in the manner of hand-cut dovetails.

Does Infinity Tools offer a set that covers multiple joinery profiles in one purchase?

Yes. The 1/2" Shank 3-Piece Ultimate Joinery Router Bit Set bundles complementary joint profiles so you can tackle multiple joint types without assembling a set piece by piece.

Are there shaper cutter equivalents for these joinery profiles?

Yes. Many of the joint profiles available as router bits also have shaper cutter equivalents. The Joinery Shaper Cutters collection covers lock miters, glue joints, reverse glue joints, and more for use on a shaper.

Does Infinity Tools back joinery router bits with a quality guarantee?

Yes. The Infinity Tools quality guarantee applies to its router bits. Review the full policy at enfinitytools.com/pages/quality-guarantee.
