The DEWALT MAXFIT® PH2 Phillips Impact Power Bit Set is engineered for maximum fit and durability in high-torque driving applications. Each 1-inch #2 Phillips bit features a precision-machined tip that improves fastener contact and reduces cam-out. The built-in torsion zone absorbs torque peaks to help minimize breakage and extend bit life. Impact-rated construction makes these bits ideal for use with impact drivers and standard drills in professional and DIY tasks.
