Cutting length determines how deep a mortise or groove your bit can create in one pass, which is crucial for matching the depth of your joinery or cleanout requirements. The best cutting length depends on the thickness of your material and your specific project needs. For shallow grooves or dados, a shorter cutting length such as 1/4" or 3/4" (as seen in the Makita 733003-4A or Amana Tool 45460-S) is suitable. For deeper mortises, bits like the Amana Tool 45427 with a 2-1/2" cutting height allow for deeper cuts in thicker stock. A variety of cutting lengths ensures you can find the right bit for anything from fine inlay work to robust joinery.
