The FROST Professional Tubing Notcher is designed with the Professional Fabricator in mind to create precision “fishmouth” notches within a wide range of angles from 90° to 140° in tubing up to 3″ diameter using a hand drill with a 1/2″ or larger chuck. Equipped with roller bearings and a 25 mm steel shaft, this notcher should provide years of reliable service. SAFETY Keep fingers and hands away from moving parts while operating this tool. Always wear proper hand and eye protection when metal cutting.
