Milwaukee 49-56-9305 Big Hawg Hole Cutter Arbor 5 Pack

Product Description

The MILWAUKEE ELECTRIC TOOL CORP 49-56-9305 is a carbide-tipped arbor designed for use with Big Hawg hole cutters in nail-embedded wood and abrasive material applications. The 7/16 inch quick-change shank allows fast bit swaps without tools, keeping workflow moving on framing and rough-in jobs. Carbide tipping delivers up to 50 times the service life compared to standard arbors in nail-embedded conditions, and the exclusive bit geometry assists with plug removal after each cut. Each package contains 5 arbors, making it a practical stocking option for crews running multiple hole cutters on the same job.

This arbor is suited for residential and light commercial rough-in work where hole cutters regularly encounter embedded nails, screws, or abrasive substrate. Typical applications include drilling through framed walls, subfloors, and structural lumber for pipe, conduit, and cable runs. The quick-change 7/16 inch interface is compatible with drills and driver setups commonly used by plumbers, electricians, and HVAC installers who need consistent hole sizing through mixed or reclaimed materials.
