IS Counterbore/Countersink
Freer Tool & Supply’s IS counterbore and countersink collection supports clean, accurate hole finishing and proper fastener seating in machining, fabrication, and assembly work. Counterbores create flat-bottom recesses for socket head and cap screws, while countersinks add the chamfer needed for flat head screws and smoother hole entrances—helping improve fit, alignment, and overall assembly quality.
