Worth it for contractors who cut holes daily across multiple trades. The 28-piece kit delivers complete size coverage from 3/4” to 4-3/4” with Milwaukee’s lifetime tooth break warranty — the only one in the industry. At 4.5 stars across 4,287 reviews, it’s earned its reputation.
Skip it if you only drill occasional holes in wood. This kit targets metal-cutting pros who need hole saws that survive nail strikes, conduit, and steel studs. The premium price reflects commercial-grade durability, not weekend projects.
Complete Kit Configuration
The 28-piece set provides 22 hole saws covering every common trade size. You get the standards — 1”, 1-1/2”, 2”, 2-1/2”, 3”, 4” — plus the oddball sizes that save trips to the store when plans change.
The kit includes arbors, pilot bits, and a heavy-duty carrying case with removable accessory box. Standard 1/2” and 3/4” drill chucks/arbors compatibility means these work with your existing drills.
| Size Range | Details |
|---|---|
| Minimum diameter | 3/4” (0.75”) |
| Maximum diameter | 4-3/4” (4.75”) |
| Total hole saws | 22 |
| Total pieces | 28 |
The case actually holds up to jobsite abuse. Too many hole saw kits come in flimsy plastic that cracks the first time it falls off a tailgate. Milwaukee’s case protects your investment.
Durability That Pays For Itself
Milwaukee backs these with the industry’s only Lifetime Tooth Break Warranty. Break a tooth cutting metal? They’ll replace it. No other manufacturer makes that promise.
The Ice-Hardened technology delivers 50% longer life versus competitors through extreme temperature treatment. Combined with 8% cobalt alloy bi-metal construction and RIP GUARD teeth, these hole saws handle abuse that destroys standard bi-metal saws.
| Durability Feature | Specification |
|---|---|
| Tooth design | 3.5 TPI (Teeth Per Inch) |
| Construction | Bi-Metal with 8% cobalt alloy |
| Coating | RIP GUARD™ / Ice-Hardened™ |
| Warranty | Limited Lifetime Tooth Break Warranty |
The 3.5 TPI tooth geometry cuts aggressively through metal while clearing chips. Finer teeth clog. Coarser teeth grab and stall. Milwaukee dialed in the sweet spot for production cutting.
Time-Saving Design Features
Plug Jack slots allow quick plug removal without extra tools. Anyone who’s wasted 10 minutes digging out a jammed wood plug knows this matters. The slots let you pop plugs with a screwdriver instead of destroying them with pliers.
The all-access slot design increases chip ejection, keeping cuts cooler and faster. Heat kills hole saws. Better chip clearing means less heat buildup, which means more cuts before the teeth dull.
Milwaukee’s Rip Guard tooth form is claimed to be the strongest in the industry, providing increased longevity and resistance to breakage during demanding applications. The reinforced tooth geometry handles nail strikes without shattering like standard hole saw teeth.
These design choices add up. Faster plug removal, cooler cutting, stronger teeth — each saves minutes per hole. Multiply that across a commercial job and the productivity gains become obvious.
FAQ
What materials can these hole saws cut? General purpose metal, wood, and plastic cutting, plus electrical installations, plumbing, and industrial maintenance applications. They’re optimized for metal with the 3.5 TPI design but handle mixed materials on typical jobsites.
Are special arbors needed for these hole saws? No. They work with standard 1/2” and 3/4” drill chucks/arbors. Use your existing arbors or the ones included in the kit.
How does the lifetime warranty work? Milwaukee offers a Limited Lifetime Tooth Break Warranty. If teeth break during normal use cutting recommended materials, Milwaukee replaces the hole saw. This covers tooth breakage only, not normal wear.
What’s the actual hole saw coverage in the kit? The kit includes: 3/4”, 7/8”, 1”, 1-1/8”, 1-1/4”, 1-3/8”, 1-1/2”, 1-3/4”, 2”, 2-1/8”, 2-1/4”, 2-1/2”, 2-5/8”, 3”, 3-1/4”, 3-1/2”, 3-3/4”, 4”, 4-1/8”, 4-1/4”, 4-3/8”, 4-1/2”, 4-5/8”, 4-3/4”. That’s comprehensive coverage for electrical, plumbing, and HVAC work.
Are these worth the premium over import hole saws? For daily commercial use, absolutely. The 50% longer life claim plus lifetime tooth warranty changes the math on tool cost. Contractors who track tool expenses find premium hole saws cost less per cut than bargain sets that fail constantly.
