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.

It is best to start work by cutting the tongue, and finish with the groove, in case your blade has dulled a bit. The quality of finish on the groove is less important.

To ensure straight cuts it is best to start the cut at the far end of the board. Start the second cut 6"-10" back from the first and repeat until you are taking a full length cut. Hold the fence firmly against the work until the full length cut is established.

The one-piece blade fits tightly on a milled track on the body casting. To adjust depth of cut, set by eye and take a test cut. Tap the back of the blade with a small hammer to increase depth. These tools are meant to take a thick shaving. Geometry: The blade is bedded bevel-down at 45°.

Blade Sharpening:

The blade comes ready to use. Slight additional honing will increase performance. A secondary bevel of up to 5 degrees helps achieve a razor edge quickly. Sharpening the blade square is particularly important on this plane. For more information on advanced sharpening we suggest David Charlesworth’s DVD Hand Tool Techniques Part 1: Plane Sharpening.

Tool Care


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.
