The Milwaukee Electric Tool Corp 49-56-9275 is a large-diameter carbide-tipped hole saw designed for cutting through tough materials in demanding trade applications. Measuring 6.25 inches in diameter, this BIG HAWG hole saw uses carbide teeth to maintain cutting performance in materials that quickly dull standard bi-metal tooth profiles. It is built for electricians, plumbers, HVAC technicians, and general contractors who need consistent, repeatable cuts in wood, engineered lumber, fiber cement, and similar substrates. The large-diameter format makes it well suited for running conduit, large-bore pipe penetrations, and ductwork openings through framing and structural panels.
This hole saw is intended for professional trade use where large-diameter penetrations are required. Typical applications include rough-in work for plumbing stacks, HVAC duct openings, and electrical conduit runs through floor and wall framing. The 6.25-inch cut diameter accommodates a wide range of pipe and conduit sizes commonly encountered in commercial and residential construction and service work. It is sold in a package quantity of 10 units, making it practical for stocking a service van or job-site supply.
Designed as an OEM-style replacement and standard production hole saw compatible with common arbor-drive hole saw mandrels used across the trade.
Installation of this hole saw should be performed by a qualified tradesperson using appropriate personal protective equipment including eye and hearing protection. Ensure the arbor mandrel is properly seated and secured before beginning any cut, and verify the workpiece is firmly clamped or braced. Always de-energize and lock out any nearby electrical circuits or mechanical systems before cutting penetrations in walls, floors, or ceilings. Follow applicable NEC, IPC, or IFGC clearance and firestopping requirements after penetrations are made.
