IS Countersinks & Deburring

Freer Tool & Supply’s IS countersinks and deburring tools help you produce clean edges, proper fastener seating, and a more professional finish across machining, fabrication, and assembly work. Countersinks create the chamfer needed for flat head screws and smooth hole entrances, while deburring tools remove sharp edges and burrs that can impact fit, safety, and downstream processes like coating or inspection.
