The DEWALT DW7342 12-1/2 in. Steel Disposable Reversible Planer Knives are replacement planer knives made for DEWALT DW734 planers. This is a planer knife set designed for resurfacing wood with clean, consistent cuts in a benchtop planer. Model Number: DW7342. If your current knives are leaving tear-out, ridges, or a rough finish, this 3-pack gives you a direct replacement set built to get your planer back to work.

What matters here is edge life and downtime. DEWALT builds these knives from M2 laminated tool steel, which is known for holding an edge longer than more basic knife materials. On the job, that means more footage between changes when you're running hardwood, softwood, or general stock through the planer. Because the knives are double-sided and reversible, you get a second cutting edge before the set is done, which helps stretch value and keeps you moving.

DEWALT also made the knife change process easier than it needs to be on a lot of older accessories. The machined locator pins and locator holes are there for a reason: they help position the knives correctly on the cutter head so alignment goes faster and with less guesswork. That is a real benefit for anyone maintaining a planer in a small shop or on a punch-list schedule where lost time matters.

This accessory is built specifically around wood planing, not general cutting. These high speed steel planer blades are intended for wood material removal and finish improvement in a planer, whether you're flattening rough stock, reducing board thickness, or cleaning up surfaces before sanding. For woodworkers and trim guys, sharp planer knives are one of those small maintenance items that make a big difference in final surface quality.

The DEWALT DW7342 12-1/2 in. Steel Disposable Reversible Planer Knives are a good fit for owners of the DEWALT DW734 who want a straightforward replacement instead of experimenting with off-brand blades. You get the right length, the right fit, and a reversible design that makes sense for regular shop use. If you rely on your planer for furniture work, jobsite trim prep, or general milling, this is the kind of consumable worth keeping on the shelf before your current set gives up in the middle of a project.
