Cut clean mortises by hand! The Mortise Chisel Insert allows you to do hand square mortises quickly and accurately without having to set up your mortise machine. Works with the Mortise Chisel Handle (#43610, Sold Separately). Simply start your mortise by drilling holes with your Forstner bit. Then clean-up the mortise using this 6-1/2" solid Ash handle and any mortising chisel with a 5/8" shank. Cuts clean, precise mortises where mortising machines cant access or when you just have a few to do and dont want to set up your mortise machine. Note: Chisels shown not included.
