IRWIN® Screwdriver Bit Sets

Stand up to Tough Drill Jobs With Screwdriver Bit Sets

Shorten job times with versatile power Screwdriver Bit Sets provide.
Insert Bits are engineered for hand-driving applications or with power tools (with a bit holder). Bits are fast and easy to change. Universal 1/4" hex shank fits most tools and adapters. Power Bits are specifically designed for higher torque applications with power tools. Longer length fits hard-to-reach areas.
Nutsetters combine heavy-duty magnetic power and high-performance materials for better control. Drive faster on sides instead of forcing corners to turn. Nutsetters maintain the original shape of the fastener--reduces breaks and strips.
Screw Guides hold longer fasteners in place--guide sleeve retracts as the fastener is driven in. Ideal for hard-to-reach applications. Screw Guides reduce fastener wobble and slips. Magnetic design secures fastener. Designed for Insert Bits only. Choose from 24-Piece (No. 147182) and 33-Piece (No. 147183) Screwdriver Bit Set.
