The IRWIN 92011 is a No. 2 Phillips insert bit designed for use with power tools and manual bit holders in professional trade and light industrial applications. The bit measures 0.25 inches in hex shank diameter by 1 inch in working length, making it a standard insert-style bit suited for production work, assembly, and fastener installation. Each pack contains 25 bits, providing enough supply to support ongoing jobsite use without frequent restocking. Licensed electricians, plumbers, HVAC technicians, and general contractors commonly keep insert bits on hand for panel work, fixture installation, and equipment assembly tasks.
The 92011 is a general-purpose insert bit appropriate for residential and light commercial applications wherever a No. 2 Phillips drive fastener is used. Typical uses include driving screws into electrical boxes, ductwork flanges, equipment housings, and structural components. The 1-inch length fits standard quick-change bit holders and most power screwdriver chucks. The 25-piece pack format is well suited for shop stocking, service van kits, or crew supply.
Designed as a standard 0.25-inch hex insert bit compatible with power drills, impact drivers, and manual bit holders that accept 1-inch insert-style bits with a No. 2 Phillips drive.
Insert bits should be seated fully into the bit holder before applying torque to prevent cam-out or premature wear. Ensure the fastener head recess is clean and free of debris before driving to maintain proper bit engagement. When using with an impact driver, select a bit holder rated for impact use. Replace worn bits promptly, as a damaged Phillips profile increases the risk of fastener head damage.
