INDUSTRIAL-GRADE STAINLESS PENETRATION
When you're facing down a NEMA 4X stainless steel enclosure, standard bi-metal hole saws simply won't cut it. The Milwaukee 49-57-8643 is engineered for the high-volume industrial electrician who demands precision and longevity in the toughest alloys. This one-piece carbide cutter eliminates the wobble of modular systems, providing a rigid, high-torque solution for punching clean conduit entries without burning through bits or compromising the structural integrity of the panel.
- / Advanced Carbide Teeth deliver maximum tool life when navigating high-grade stainless and hard metals.
- / Integrated Stop Shoulder prevents over-drilling, limiting depth to 3/16 in. to protect internal wiring and components.
- / Spring-Loaded Pilot Bit ensures consistent slug ejection for rapid-fire hole production on the assembly floor.
- / 3-Flat Shank geometry optimizes the connection to your drill/driver, eliminating chuck slippage under heavy loads.
- / Solid One-Piece Design provides superior concentricity and durability compared to multi-part arbor systems.
