The Milwaukee 49-22-4105 HOLE DOZER Electricians Hole Saw Kit is a 19-piece hole saw kit built for electricians and tradespeople who need common hole sizes ready to go in one organized case. This is a hole saw kit designed for cutting clean holes in metal, wood, and drywall. Model Number: 49-22-4105. If you do conduit work, panel work, box installs, or general rough-in, this kit is set up around sizes you will actually use instead of filler pieces that sit in the truck.

The core of this kit is Milwaukee's HOLE DOZER bi-metal hole saw line, built around a 3.5 teeth-per-inch tooth design for longer life in metal applications. That matters because metal is where cheaper hole saws slow down, lose teeth, or start walking. Milwaukee also uses ALL-ACCESS SLOTS, which do more than just look different. They make slug removal easier, improve pilot visibility for better placement, and help eject chips faster so the cut runs cooler and cleaner.

Milwaukee also adds a thermoset coating to reduce friction and drag. In practical terms, that means the saw gets through the cut with less resistance, which is especially useful when you are running cordless drills on repeated holes. Milwaukee specifically calls out improved cordless efficiency and more holes per charge, so this kit makes sense whether your everyday setup is corded or cordless.

This set is not just about the saws. The case is a real part of the value here. It uses interchangeable pegs for customizable layout, reinforced grids to keep the hole saws secure, and a removable accessory box for arbors, pilot bits, and related parts. That sounds simple, but on the job it means less time digging for the right size and less chance of parts getting scattered or lost. For a kit that may bounce around in a van every day, that matters.

The included range covers 14 HOLE DOZER bi-metal hole saws from 3/4 inch through 4-3/4 inch, plus both a small thread arbor with a 3/8 inch shank and a large thread no-wobble arbor with a 7/16 inch shank. A high speed steel pilot bit is also included. That combination gives you a setup that can handle small and large hole saw sizes without piecing together extra hardware separately.

Milwaukee positions this kit as multi-purpose, and the product data supports that. It is suited for general purpose cutting across metal, wood, and drywall, but the electrician-focused size selection is what really defines it. If your work regularly involves cutting openings for conduit, fittings, cans, or access points, the sizing and case layout make this kit more useful than a random mixed hole saw assortment.

Another important detail is durability. Milwaukee backs these HOLE DOZER bi-metal hole saws with a Limited Lifetime Tooth Break Warranty, and the product is listed as made in the USA. That does not replace good technique, but it does tell you Milwaukee expects these saws to hold up under real jobsite use rather than light-duty weekend work.

Who should buy it? Electricians are the obvious fit, but it also makes sense for maintenance crews, general contractors, remodelers, HVAC techs, and plumbers who need a broad hole saw range in one case. If you want a job-ready hole saw set with strong metal-cutting performance, organized storage, and common trade sizes, this is the kind of kit that earns its spot in the truck.
