With the straight Fein cutter blade, you quickly and efficiently remove tough elastic sealants and expansion joints without tedious manual scraping. Thanks to the universal straight profile, the blade glides smoothly through joints to deliver a clean cut along joint flanks. This protects surrounding concrete edges or facade surfaces and provides ideal preparation for fresh sealant application. Designed for Fein oscillating multi-tools such as the SuperCut and MultiMaster MM 700, this convenient 5-pack ensures you have ample supply to tackle demanding indoor and outdoor renovation jobs with total control.
