IS Countersinks
Freer Tool & Supply’s IS countersinks collection helps you create clean chamfers and precise countersunk holes for flat head screws and finishing work. Countersinks are commonly used to deburr drilled holes, improve fastener seating, and produce a smooth, professional edge—reducing burr-related assembly issues and improving part appearance in machining and fabrication.
