Make an informed fit.

Practical references for identifying your machine and understanding its cutting parts.

How to find the right planer blades

Begin with the machine identity. A nominal cutting width is a useful description, but it is not a replacement part number.

Measurements help compare a documented replacement. They cannot, on their own, establish compatibility.

Reversible, disposable and sharpenable describe different properties. One label should not be used to infer the others.

A reliable fit claim connects a named machine to a named part. Equal dimensions alone leave too many questions unanswered.

Identify the cutterhead first. Full-width knives and individual inserts are different kinds of replacement consumables.

Start with the exact jointer model, then compare the replacement knife specification and mounting system.
