Stanley No. 49 Tongue and Groove Plane – The Precision Match Plane for Perfect ½″ T&G Joinery

1. Introduction

The Stanley No. 49 Tongue and Groove Plane is the companion to the popular Stanley No. 48, designed specifically to create perfect, centered tongue-and-groove joints in ½″ stock. Featuring a reversible body, dual fixed cutters, and a smart sliding-fence system, the No. 49 allows woodworkers to cut both the tongue and the groove simply by flipping the plane end-for-end.

Lightweight, accurate, and brilliantly simple, the No. 49 is ideal for flooring, beadboard, drawers, cabinet backs, casework, and all traditional ½″ matchboard projects. Its intuitive dual-mode design makes it faster and easier to use than combination planes or electric routers—especially for repeated T&G production.
