A Router Bit Collection Just For Flooring

If you're interested in making your own hardwood flooring, consider the time-tested Slip Tongue Joint. When installing new wood flooring, boards are first positioned at an angle and then pivoted into place. If you use a traditional square-shaped spline, the square edges will get in the way during that pivot and could crack the delicate shoulders of the grooves.

A Slip Tongue Joint solves this problem by rounding the edges of both the spline and the grooves. When you angle your new floorboards into place, the rounded edges slide right into place and your joints align easily. You get more strength than would be afforded by a bare edge-joint, and you can even use the Slip Tongue joint to join edge grain to edge grain wood.

The 00-127 Slip Tongue Flooring Router Bit comes with a 05-127 bit to create the radiused grooves, and a 54-520 Bullnose Router Bit to create a 1/4" rounded edge for your splines.

The kit includes a 1/4" x 1/2" Bearing to let the Slip Tongue Router Bit produce a 1/4" x 3/8" deep groove that can typically be used with a 1/4" x 5/8" to 1/4" x 3/4" Slip Tongue spline. When used with the included 1/4" x 5/8" Bearing it will produce a 1/4" x 5/16" deep groove that can typically be used with a 1/4" x 1/2" to 1/4" x 5/8" Slip Tongue spline. And it includes the bearing stop collar and allen kit for fast bearing changes.

Kit Includes:

  • The Slip Tongue Flooring Router Bit (05-127)
  • A 1/4" x 1/2" Bearing (BR-109) and a 1/4" x 5/8" Bearing (BR-111)
  • The 54-520 Bullnose Bit
  • Comes with a stop collar kit

Benefits:

  • Create hardwood flooring that installs smoothly without damaging your wood
  • Use as an alternative to edge-to-edge joints for much stronger, more stable glue-ups

Customer Reviews (4.4 / 5 · 5 reviews)

Andrew ★★★★★

I'd been struggling with tongue-and-groove joints on my white oak floor until these bits cut them perfectly—the slip tongue design locks boards together seamlessly. Saved me hours of sanding and fitting.

Steven L. ★★★★★

Finally got around to installing some hickory flooring with these bit and the slip tongue cut was perfectly clean on the first try. The carbide tips held up through the entire room without any dulling or burning.

Joshua ★★★★☆

The bit’s carbide tips held their edge nicely through a full room of red oak, though I did have to adjust my router speed slightly to avoid burning on the slip tongue pass.
