The Makita 3-1/4 in. Double Edged Tungsten Carbide Planer Blade Set is a replacement planer blade set for portable 3-1/4 inch planers. This is a planer blade set designed for smoothing and sizing wood with a handheld power planer. Model Number D-46246. If your planer is still running strong but the cut quality is falling off, this is the kind of upgrade that gets it back to clean, consistent passes without changing the tool you already trust.

The big story here is the blade material. Makita uses tungsten-carbide construction for longer life and smoother cutting than basic blades. In real use, that matters when you are knocking down proud edges, fitting doors, easing framing lumber, or cleaning up stock in the shop. A harder cutting edge stays sharp longer, which helps the planer cut cleanly instead of tearing at the grain once the blade starts to wear.

The double-edged design is just as important as the carbide. When one edge is spent, you flip the blade and go back to work with a fresh edge. That gives you more usable life from the same set and cuts down on downtime. For anybody using a planer regularly, that simple reversible design saves both time and money because you are not burning through blades as quickly.

Makita also calls out easy setup and depth adjustment. That matters because planer blade changes are only worth doing if you can get back to accurate cutting without a fight. These blades are made for Makita 3-1/4 inch planer models KP0800K, KP0810, XPK01, N1900B, and 1902, and they are also described as fitting most major brand 3-1/4 inch planers. For Makita users, that gives you a direct replacement option built around the planer sizes you already run.

This set includes two blades, which is what you need for the planer head. Makita also notes compatibility with set plate 343433-9, which is useful if you are doing blade installation and alignment. The actual benefit is simple: less guesswork during setup and a better shot at getting the planer cutting evenly across the full width.

Who should buy this? Woodworkers, remodelers, carpenters, punch-list crews, and serious DIY users who rely on a 3-1/4 inch planer for fitting, trimming, and cleanup work. If you own one of the listed Makita planers, this is the straightforward replacement. If you run another major-brand 3-1/4 inch planer and need reversible carbide blades, it is also worth a close look because fit across select competing models is part of the design.
