Milwaukee 49-56-0320 High-Speed Steel Adjustable Hole Cutter

The Milwaukee 49-56-0320 Adjustable Hole Cutter is a professional-grade drilling accessory built with a high-speed steel (HSS) tooth for durable, repeatable performance on the jobsite. Designed to cut clean, precise round holes of varying diameters, this adjustable hole cutter attaches to a standard power drill and eliminates the need for carrying multiple fixed-size hole saws. The adjustable configuration allows tradespeople to dial in the exact hole diameter required for the task at hand, helping reduce tool inventory and job site setup time.

Key Features

  • Adjustable Cutting Diameter: The adjustable design lets users dial in the desired hole size with a single cutter, reducing the number of individual fixed-diameter hole saws needed for a job.
  • High-Speed Steel (HSS) Tooth: The HSS cutting tooth resists heat buildup and wear during use, delivering longer tool life and cleaner hole edges compared to standard carbon steel cutting edges.
  • Milwaukee Model 49-56-0320: Part of Milwaukee's line of drilling accessories engineered for durable, consistent performance in demanding professional trade applications.
  • Drill-Powered Operation: Designed to be driven by a standard power drill, making this cutter a practical, space-saving accessory for electricians, plumbers, and other tradespeople who need on-site hole cutting flexibility.
  • Single-Tool Versatility: By adjusting to different hole diameters, the 49-56-0320 helps consolidate multiple hole saw sizes into one accessory, streamlining tool kits on service trucks and job sites.

Milwaukee 49-56-0320 – Frequently Asked Questions

1) What materials will the Milwaukee 49-56-0320 adjustable hole cutter cut?
The cutting tooth is high-speed steel, which suits wood, plastic and thin metal panels. HSS handles the heat of those cuts better than carbon steel edges. For hard or abrasive material like tile or masonry, this is the wrong tool, a carbide-tipped cutter is what you want there.
2) If I only ever cut one hole size, is there a fixed-diameter cutter instead of the Milwaukee 49-56-0320?
Yes. The Milwaukee 49-56-0320 is an adjustable hole cutter with a high-speed steel tooth, so one cutter dials in a range of diameters. If you cut a single repeated size, the Ideal Industries 36-801 DEADEYE is a carbide tipped hole cutter fixed at 7/8 inch, which is a common size for electrical knockouts and connectors. Choose the Milwaukee when hole sizes vary from opening to opening, and the fixed 7/8 inch Ideal when the size never changes.
3) I need to cut a single gang box opening, not a round hole. What do I use?
The Milwaukee 49-56-0320 cuts round holes of adjustable diameter and will not produce a rectangular box opening. For single gang device boxes, the Rack-A-Tiers 42700 Q-Bit hole cutter cuts a 2-3/8 inch by 3-3/4 inch single gang opening. Keep the Milwaukee for round penetrations such as conduit and pipe runs, and use the Q-Bit for the device box cutouts.
4) Do I need a special tool to run the 49-56-0320, or will my cordless drill work?
It runs off a standard power drill. No dedicated driver or mandrel system is called for, which is why it gets used for electrical rough-in and plumbing or HVAC installs where you are working out of a drill case.
5) Adjustable hole cutter or a carbide-tipped fixed cutter, which should I buy?
Take the adjustable Milwaukee 49-56-0320 when hole sizes vary job to job and you would rather set the diameter than carry a kit. Take a fixed carbide-tipped cutter, like the Ideal Industries 36-801 DEADEYE in 7/8 inch, when you drill the same size repeatedly, especially in metal, where carbide holds an edge longer than high-speed steel.
6) What is the difference between the high-speed steel tooth on the Milwaukee 49-56-0320 and a carbide tipped cutter?
The Milwaukee 49-56-0320 uses a high-speed steel tooth, which resists heat buildup and wear and leaves clean hole edges in wood, plastic, and thin metal panels. The Ideal Industries 36-801 DEADEYE is carbide tipped instead. Carbide tipping is the harder cutting edge, while the Milwaukee's advantage is that the single HSS cutter covers a range of diameters rather than one fixed size.
7) Can the Rack-A-Tiers 42700 replace the Milwaukee 49-56-0320 in my service truck kit?
They are not interchangeable. The Rack-A-Tiers 42700 is a Q-Bit series cutter sized for a 2-3/8 inch by 3-3/4 inch single gang opening, a single fixed cutout shape. The Milwaukee 49-56-0320 is drill-powered and adjustable, which is what lets it replace several fixed-size round hole saws in one accessory. An electrician doing rough-in typically carries both.
