Best Hole Saw Kits of 2026

The Milwaukee Hole Dozer kit is the default recommendation for pros and serious DIYers, and the reason is range plus toughness in one case. This 28-piece set spans nearly every size you need, from a 3/4-inch cutter up to a 4-3/4-inch saw, so it earns the all-purpose pick by covering door locks, vents, and recessed lights without a second kit.

The standout feature here is the “Ice Hardened” cryogenic treatment process. Milwaukee claims this makes the bi-metal teeth up to 50% more durable than standard heat-treated saws. In practice, this means you can hit a nail hidden in a stud and the teeth won’t sheer off instantly.

We also love the “Plug Jack” slot design. These deep access slots on the side of the cup allow you to use a screwdriver to pry out stuck wood plugs easily, which is usually the most frustrating part of using a hole saw. It comes with three arbors and pilot bits, all packed in a sturdy case with room for expansion.

The Diablo plumbing set is built around a deep 2-3/8 inch (60mm) cutting capacity, well past the roughly 1-5/8 inch depth of a standard hole saw. That extra depth lets you pass a 2×4 stud in one pull instead of stopping to knock out a stuck core, which is the difference that earns it the plumbing pick for anyone running drain lines through framing.

The Snap-Lock Plus mandrel is the standout: cups change in seconds, one-handed, with no wrench. One arbor covers every cup size in the set, so you are not hunting for the right adapter mid-job.

Sizes run up to 4-1/2 inches for large waste pipes, and the variable-pitch teeth cut with less vibration in mixed material. It is a heavier investment than a basic kit, which only makes sense if you drill holes often enough to value the speed.

A standard bi-metal saw struggles in stainless steel, electrical panels, and mild steel, where the teeth wear flat fast. This Greenlee set runs carbide-tipped teeth that hold an edge in those abrasive metals far longer than bi-metal. The carbide is the reason it earns the metal pick.

The six cutters run from 7/8-inch to 2-inch, the common knockout sizes for electricians installing conduit. A built-in flange stop keeps the saw from plunging too deep and damaging wiring or equipment behind the panel, a real safeguard when you cut into a live enclosure.

The spring-loaded pilot drill ejects the metal slug automatically when the cut finishes, so there is no prying a stuck plug out of a shallow cup. It is a small, focused set rather than an all-purpose kit, which is the trade-off for metal-grade cutters.

DeWALT tailored this kit specifically for the needs of electricians. You won’t find random sizes here; every saw in this eight-piece set corresponds to common conduit and pipe sizes found in residential and commercial wiring.

The saws feature a bi-metal construction with M3 steel cutting edges, making them tough enough to cut through metal electrical boxes or wood studs. DeWALT’s tooth design is aggressive, clearing chips fast to keep the blade cool.

We particularly like the “Quick Change” mandrels included in the kit. They hold the saw securely but allow you to swap sizes without hunting for a wrench. While the case is compact and durable, some users have noted that the pilot bits can be prone to snapping if you apply too much lateral pressure.

Drilling through glass, granite, or ceramic tile requires a delicate touch and a specific tool: the diamond hole saw. The 3 Otters set uses a nickel-plated body coated in diamond dust to grind through hard, brittle materials without shattering them.

This 15-piece kit offers a size range from 0.24 inches to 2 inches. It is perfect for installing shower doors, drilling drainage holes in flower pots, or running pipes through a tiled backsplash. Unlike toothed saws, these do not have a pilot bit in the center.

Because there is no pilot bit, starting the hole can be tricky (you have to start at an angle). Also, remember that diamond saws must be used with water to keep them cool; otherwise, the coating will burn off.

Most cheap kits cut corners with carbon steel, so the teeth give up the first time they touch metal. The HYCHIKA set is the rare budget kit that uses bi-metal cups, the same high-speed-steel-and-cobalt construction the trade-grade saws rely on, which is why it earns the value pick over a carbon-steel set at a similar price.

The 11 cups run from 19mm to 68mm (about 3/4 to 2-11/16 inch) and handle soft metal, wood, PVC, plastic, and gypsum board, so one kit covers recessed lights, door hardware, and thin sheet metal. A chip-clearing slot on the side of each cup helps push the slug out and keeps heat down on longer cuts.

The limits are real: maximum cutting depth is 40mm (about 1-9/16 inch), so it will not pass a deep stud in one go, and there is no cup larger than 68mm for big vents. The two-arbor system also lacks the tool-free quick-change of premium kits, so swapping sizes means threading cups on and off. For light-to-medium home work it is a lot of capability for the money.

For a hobbyist who works mostly in wood, paying for trade-grade bi-metal is money spent on durability you will rarely use. The KATA kit leans into that: heat-treated carbon steel cups keep the price low and hand you a wide spread of sizes, which is what a woodworker actually wants for one-off cuts.

The range is the draw here, 17 cup sizes from 3/4 inch up to a full 6 inches, so it covers everything from cable grommets and recessed-light cans to large vent and speaker openings that a typical kit tops out below. The black anti-rust coating and sharp serrations start cleanly in softwood, plywood, MDF, drywall, and PVC, and a labeled case keeps the many sizes sorted.

The carbon steel sets the boundaries. It is not for metal, tile, or hardwoods, where the teeth dull fast, and depth is capped around 1 inch, so it will not pass framing lumber. Keep the speed down to avoid burning, and it stays a strong-value kit for soft-material work.
