Woodworkers love to make custom flooring. And now with the Infinity Tools matched Floor Making Router bit sets you can choose from three of the most popular options used in the flooring industry. Each router bit set is C.N.C machined to guarantee a perfect fit and we finish each one with our silver non-stick coating for years of trouble-free service.

Choose from three options to fit your needs:

61-504 - V-Tongue and Groove Router Bit Set

Unlike most square profile tongue and groove router bits, our matched V-Tongue & Groove set produces an elegant 45° "V" groove in stock from 5/8" to 7/8" thick. This type of joint is ideal for custom flooring, wainscot paneling, cabinet backs, and even Shaker-style cabinet doors. Both router bits feature bearing guides that will make setting-up and running quick and easy. Features a 1/4" thick tongue and groove joint.

61-509 - Tongue and Groove Flooring Router Bit Set

This matched Flooring Router Bit Set is great for making hardwood flooring with stock up to 1-1/8" thick. The tongue cutter features a 1/2° angle which produces a slight gap at the bottom of the joint to ensure a tight-fitting joint. The tongue and groove cuts are also approximately 1/16" offset to allow room for expansion.

61-511 - Floor Making Router Bit Set with Nail Slot
(Includes Free Setup Block)

For working with stock up to 3/4" thick, the tongue cutter on this router bit set features a special nail slot profile for professional results. The rounded profile at the bottom of the joint prevents debris on the floor from getting in the way of a nice tight fit. Both bits feature a high quality bearing for ease of setup while the tongue and groove cuts are approximately 1/16" offset to allow room for expansion.

This set also includes a Complimentary Setup Block (SET-511) for use with 3/4" material to help you set the proper bit height.

The template made resetting the router bits easy. Although planing is still needed the bits have stayed sharp and dependable.

I purchased these a while ago and I've been running them. I've looked back at my shaper's manual and noticed the speeds were 7,000 and 11,000 rpm. I wanted to make sure I was being safe while using these but I do not see a rpm suggestion anywhere for the See more »

This may be a stupid question... But in one video I got the impression it had a 1/2"ùshank that could be used in regular router tables...? I'm wrong correct? Shapers only not router tables? See more »

The Insert Pro Raised Panel Shaper Cutter is for use in Spindle Shapers/Moulders only. It is definitely no for use in router tables. This is a 1-1/4" bore cutter and required a 1-1/4" spindle or a pair of T-bushings to reduce down to smaller spindle sizes

Choose from three options: V-Tongue & Groove; Tongue & Groove or our Floor Making Router Bit Set (w/nail slot) and make your own beautiful hardwood floors that will last a lifetime.

Its that time of year when we all start looking at home remodeling projects.  These are the days when the bathroom or kitchen remodel happens, the buildout of the wet bar in the basement, or possibly the new backyard deck.  One project that I frequently get asked questions about is how to make custom flooring.  So how do I turn my beautiful hardwood lumber into flooring?  It's easy with Infinity Tools Tongue and Groove Flooring router bit set with nail slot. 

Our 61-511 floor-making router bit set is perfect for turning your lumber into beautiful custom hardwood floor planks. Made with finely polished micro-grade carbide cutting edges, this router bit set will stand up to the abuse of cutting loads of board footage while producing a specially engineered male and female profile that makes installation fast and easy. A unique feature of our bit set is the integrated nail slot above the tongue profile. This creates a space for your nail to be inset so the tongue and groove will fit together without any binding. There is also a 1/16" gap in the tongue and groove profile that helps take into account seasonal wood movement and also provides a nice glue trough. Another nice feature of our floor-making router bit set is the radius that they leave on the bottom of your board. This detail helps to ensure that loose debris or uneven floors do not affect how tightly you can join the boards, brilliant! 

The integrated nail slot makes fitting the tongue and groove easy. No more fighting the nail when sliding the flooring together.

The set-up on these router bits is very easy.  All referencing is done from the flooring bottom since the tops will get sanded flush.  I typically start with the tongue side router bit. Flush the bearing up to the fence and raise or lower the router bit until the round over on the bottom of the bit will create a perfect round over on the bottom of your flooring piece. For the groove side router bit, use the same reference of the fence to bearing and the round over on the bottom of the flooring material.  I will also double-check that the tongue on my previous cut piece will fit nicely into where the groove will be cut.

Flush the fence to the bearing and make sure the rounded profile on the bottom of the router bit does not cut a bead into your flooring.
