Product Description
Milwaukee 15/16 in. Hole Saw Cutter for Steel
Model Number: 49-57-8209
The Milwaukee 49-57-8209 is a 15/16 in. Hole Saw Cutter engineered specifically for hand-held drilling operations in steel — a bi-metal or high-speed steel hole saw sized for cutting precise, clean holes in steel plate, structural steel, metal enclosures, and steel sheet in fabrication, maintenance, and construction metalwork. The 15/16 in. diameter is used for conduit knockouts, electrical box openings in metal enclosures, specific bolt clearance holes, and fabrication holes in steel where the 15/16 in. bore matches the fitting, conduit connector, or fastener clearance specification. Milwaukee designs this hole saw for hand-held operation with a corded or cordless drill and the appropriate hole saw arbor — the cutter geometry, tooth pitch, and blade set are optimized for steel cutting at the speeds and feeds achievable in hand-held drill operation rather than the fixed, precisely-controlled conditions of drill press use.
The high-speed steel or bi-metal tooth construction provides the cutting edge hardness and impact toughness needed for steel hole sawing — maintaining sharp tooth edges through the cutting cycle while resisting the fracture that all-HSS blades experience in the interrupted cutting and vibration of hand-held steel drilling. Cutting fluid or oil applied at the tooth-to-steel interface during cutting improves cutting speed, reduces heat at the teeth, and extends hole saw service life in steel compared to dry cutting. The hole saw mounts on the appropriate Milwaukee arbor — verify the correct arbor specification for this hole saw diameter before ordering. The 15/16 in. size provides the specific bore dimension for conduit system fittings and hardware that requires this exact clearance through steel panels and enclosures.
