Milwaukee 3/4″ One-Piece Carbide Hole Cutter

STAINLESS STEEL ENCLOSURE PENETRATION POWER

When you’re fabricating high-volume conduit entries in 304 or 316 stainless steel panels, standard bi-metal saws won’t cut it. The Milwaukee 49-57-8605 is engineered for the industrial electrician who demands production-level speed and strict code-compliant finishes. This carbide-tipped solution eliminates the heat-hardening issues common in hard metal applications, providing the precision necessary for clean fittings and professional enclosure assemblies.

• / Advanced Carbide Teeth: Delivers superior tool life and maintains a sharp edge even when boring through abrasive stainless steel and thick-gauge alloys.
• / Stop Shoulder Design: Built-in safety collar prevents over-drilling and protects internal panel components by limiting the cut depth to 3/16″.
• / Spring-Loaded Pilot Bit: Forces the metal plug to eject instantly, streamlining workflow during repetitive hole cycles in junction boxes.
• / 3-Flat Shank: Optimized geometry prevents bit slippage within the drill chuck, ensuring maximum torque transfer and zero marring.
• / One-Piece Construction: Solid body design maximizes concentricity and durability, reducing vibration and ensuring a perfectly round hole every time.
