Irwin IR3512052C Square Recess Insert Bit 2-pack

Product Description

The IRWIN IR3512052C is a Size 2 square recess insert bit designed for driving square-drive (Robertson-style) fasteners. With a 1-inch overall length, this compact insert bit fits standard 1/4-inch hex power tool chucks and quick-change bit holders. It is sold in a pack of two, making it a practical choice for jobsite use where bit wear or loss is common. Licensed electricians, plumbers, HVAC installers, and general trade contractors routinely reach for square-drive bits when working with decking screws, electrical panel hardware, and rough-in fasteners that call for a Robertson drive profile.

The IR3512052C suits residential and light commercial installation work wherever Size 2 square-drive screws are specified. The 1-inch OAL makes it well suited for use directly in a drill or impact driver without an extension, or seated in a magnetic bit holder for added reach. Typical applications include securing electrical enclosures, mounting brackets, HVAC equipment panels, and general carpentry and rough-in tasks across trades.

Key Features

• Size 2 square recess drive profile fits standard Robertson square-drive fasteners
• 1-inch overall length fits 1/4-inch hex chucks and quick-change holders
• Pack of two bits included per unit
• Compact insert-bit format works in bit holders and direct-chuck applications

Compatibility

Designed as a standard 1/4-inch hex shank insert bit compatible with drills, impact drivers, and bit holders that accept 1/4-inch hex insert bits and require a Size 2 square recess drive.

Installation Notes

Insert bits should be seated fully into the tool chuck or magnetic bit holder before driving fasteners. When using an impact driver, verify the bit holder is rated for impact use to avoid premature bit or holder failure. Replace worn bits promptly, as a damaged drive tip can strip fastener heads and complicate removal.
