The IRWIN IR3521091C is a 6-8 slot power bit designed for driving slotted fasteners in professional-grade power tool applications. At 1-15/16 inches overall length, this compact bit fits standard power bit holders and quick-change chucks commonly found on drills and impact drivers. The 6-8 slot tip profile accommodates a range of slotted screw sizes, making it a practical single-bit solution for tradespeople who encounter varied fastener sizes on the job. Sold individually, it is suited for electricians, HVAC technicians, plumbers, and general contractors who require a reliable slotted drive bit for service and installation work.
This bit is appropriate for residential and light commercial applications where slotted fasteners are encountered, including panel work, fixture installation, and equipment servicing. Its short overall length makes it well-suited for use in tight spaces or in conjunction with a bit extension. The single-piece packaging keeps it ready for inclusion in a tool kit or service bag without excess bulk.
Designed as a standard-shank slotted power bit compatible with quick-change and standard bit holders on common drills and impact drivers.
Insertion into a quick-change chuck should be done with the tool unpowered. Verify the bit is fully seated and locked before operation. Inspect the tip for wear before use, as a worn slotted tip can damage fastener heads and increase cam-out risk. Follow tool manufacturer guidelines for maximum torque ratings when using with impact drivers.
