The MILWAUKEE ELECTRIC TOOL CORP 48-32-4606 is a 5-pack of 2-inch Square Number 2 insert bits engineered for high-demand impact fastening applications. Built on a proprietary steel heat treat process, these bits deliver maximum strength and durability under the repeated stress of impact driver use. The forged tip geometry maximizes grip in the fastener head, reducing cam-out and bit wear. A geometric shank design provides shock absorption to extend bit life. This product is suited for electricians, plumbers, HVAC technicians, and general trade professionals who rely on impact drivers throughout the workday.
These insert bits are designed for use in standard impact drivers and drills accepting 1/4-inch hex shank insert bits. The 2-inch length suits applications where compact clearance is needed or where a bit holder is used in tighter spaces. Typical use cases include panel assembly, equipment installation, and structural fastening tasks across residential and commercial job sites. The square drive profile is commonly required in decking, framing, and general construction fastening scenarios where Robertson-style fasteners are specified.
Designed as an OEM-style replacement and standard aftermarket fit for 1/4-inch hex shank impact drivers and drills accepting 2-inch insert bits with a Number 2 square drive profile.
Insert bits of this type are installed and removed by hand into any 1/4-inch hex quick-change chuck. No tools are required for bit changes. Ensure the impact driver is powered off and the trigger is locked out before changing bits to prevent accidental activation. Inspect the bit tip for wear or rounding before each use, as a worn tip increases the risk of cam-out and fastener head damage.
