Tongue and Groove Planes




Tongue and Groove Plane

Based on the Stanley No. 48 and 49, our Tongue and Groove Planes are more heavily built for sound performance with a very thick blade. Also, rather than having two separate blades, ours is a single forked blade that registers on the milled body casting to ensure squareness and equal depth of cut on both sides. Since this is a heavy stock removal tool, no fine depth adjuster is needed. The blade is 3/16" thick O1 steel. The fence is attached to the base with a center pivot screw and can be rotated and locked in tongue-cutting or groove-cutting positions.

The No. 48 centers on ¾" stock, leaving a ¼" wide tongue and .3125" deep grooves. On narrower or wider boards, the tongue will be offset from center, but still hidden within the joint. 2.90 lbs.

The No. 49, a companion Tongue and Groove Plane, is made to center on ½" stock. It will cut a .166" wide tongue and .230" deep grooves. 2.35 lbs.

The body is cast from Ductile Iron, a very strong alloy that will take a lot of abuse. These castings are fully stress-relieved, a process that removes inherent stresses and ensures that the tool will remain flat and true. Cherry knob and handle, other parts are Brass and Stainless Steel. The blade is O-1 Tool Steel hardened to Rockwell 60-62.


To protect your tools, you should oil, wax, and/or wrap them after use. At the least, wipe your fingerprints off with an oily rag. We recommend Camellia or Jojoba Oil - vegetable oil based products. They are non-toxic, odor free and easy to use. Also, in our shop, we use a fine abrasive handblock to remove any light surface oxide from tool bodies and blades. The oils and the abrasive handblock are available from us.


Materials and workmanship are guaranteed for the life of your tool. Call for repairs or replacement parts. We are available for advice if you ever have a problem using your tool.

Proposition 65 Notice:

Bronze and brass alloys contain lead, a chemical known to the State of California to cause cancer and birth defects, or other reproductive harm. Wash hands after handling.
