The Milwaukee 49-56-7010 Small Thread Hole Saw Arbor is built for professional electricians and contractors who demand reliable, consistent performance on the job site. Designed with a 3/8 in. hex shank for superior gripping capability in the chuck, this arbor eliminates slippage during demanding hole saw applications — whether you're running conduit knockouts, installing junction boxes, or cutting through panels. High-speed steel construction ensures long-lasting durability across repeated use, and compatibility with all hole saws up to 1-3/16 in. and all drill chucks 3/8 in. and larger makes it a versatile addition to any tool kit.
