The IRWIN IR3521131C is a 10-12 slot power bit designed for driving slotted fasteners in powered screwdriving applications. With an overall length (OAL) of 1-15/16 inches, this bit is sized for standard power tool chucks and impact-rated holders commonly used in construction, electrical, and mechanical trade work. It is sold individually, making it a practical replacement or addition to an existing bit set. The compact OAL suits tight-clearance fastening tasks where a longer bit would not seat properly in the driver.
This power bit is suited for use in residential and light commercial applications where 10-12 slotted fasteners are encountered. Electricians, HVAC technicians, plumbers, and general contractors regularly use slotted power bits when working with junction box covers, panel hardware, and equipment enclosures that use slotted drive screws. The single-piece packaging allows for targeted restocking without purchasing a full set.
Designed as an OEM-style power bit for use with standard hex-shank bit holders and powered screwdrivers that accept 10-12 slotted drive bits.
Ensure the power tool or screwdriver is fully powered off before inserting or removing the bit from the holder. Seat the bit fully in the chuck or bit holder before applying torque to avoid cam-out or fastener damage. Use appropriate eye protection when operating powered screwdriving tools. Follow applicable workplace safety standards when working in electrical panels or equipment enclosures.
