Ivy Classic - Square Power Bit, 2 inch #1

Built for precise control on small Robertson screws, this 2" SQ1 power bit pairs a precision-machined square tip with a rugged, heat-treated S2 tool-steel core for tight, low cam-out engagement. The extended 2" length clears chuck jaws and fittings for better sightlines, and the 1/4" hex shank locks securely into drills, impact drivers, and magnetic bit holders—perfect for cabinetry hardware, fixtures, and light assemblies.
