Worth it for contractors who need blades that last longer than a Montana winter. The kit’s carbide teeth deliver up to 50X longer life versus standard bi-metal blades, and the universal fit OPEN-LOK anchor works with Milwaukee, DeWalt, Makita, Bosch, Ridgid, Rockwell, Ryobi, and Porter-Cable tools. At 4.7 stars on Home Depot with 471 reviews, it delivers what Milwaukee promises.
Skip it if you only do occasional trim work or light remodeling. This kit shines in renovation, demolition, and anywhere hitting nails costs you money.
Blade Performance That Actually Matters
Milwaukee’s Nitrus Carbide provides 2X more cuts versus standard carbide teeth. That’s not marketing fluff — that’s fewer blade changes when you’re gutting a 1920s Kalispell bungalow full of embedded nails and mystery metal.
The real standout? Titanium-charged bi-metal blades that last up to 15X longer than high carbon steel. For contractors bouncing between job sites from Whitefish to Columbia Falls, that durability translates to carrying fewer spare blades and making fewer hardware store runs.
The kit handles metal (hardened fasteners, screws, bolts, rebar, copper), wood (hardwood, wood with nails, plywood), and construction materials (drywall, PVC, plaster, fiber cement, cement board). That covers 90% of what you’ll hit during Montana renovations — from turn-of-the-century mining town rehabs to modern mountain home remodels.
Universal Compatibility Without The Headaches
Here’s what matters: these blades fit Milwaukee, DeWalt, Makita, Bosch, Ridgid, Rockwell, Ryobi, and Porter-Cable multi-tools. The only exclusion? Not compatible with Starlock tools.
Montana contractors often run mixed tool brands — maybe Milwaukee cordless but an older DeWalt oscillating tool that still runs fine. This kit eliminates the “wrong blade for the tool” problem that wastes time on remote job sites where the nearest hardware store might be an hour away.
What’s Actually In The Box
The 15-piece kit includes specialized blades for specific tasks: carbide teeth for extreme metal cutting, titanium bi-metal in multiple sizes (3/8”, 1-3/4”, 2-1/2”), Japanese tooth blade for hardwood, standard wood blade, rigid scraper, sanding pad, and sandpaper (60 and 120 grit).
The Japanese tooth blade deserves special mention. Triple-ground, flame-hardened teeth provide approximately 2X faster cuts in hardwood — critical when trimming old-growth Douglas fir or hundred-year-old larch flooring.
| Component | Quantity | Best Use |
|---|---|---|
| 1-3/8” Titanium Enhanced Carbide Teeth Extreme Metal Blade | 1 | Rebar, hardened screws |
| Titanium Charged Bi-Metal Multi-Material Blades (various sizes) | 4 | General demolition |
| 1-3/8” HCS Japanese Tooth Blade | 1 | Hardwood flooring |
| Stainless Steel Rigid Scraper Blade | 1 | Adhesive removal |
| 3-1/2” Triangle Sanding Pad with papers | 1 + 6 | Detail sanding |
PACKOUT Integration Changes The Game
The modular blade case fits Milwaukee’s PACKOUT system. At 11.38” x 7.63” x 1.5” and weighing just 1.69 pounds, it stacks into your existing PACKOUT setup without eating valuable truck space.
Removable pegs allow storage customization — reorganize based on which blades you use most. For Montana contractors driving between job sites on rough forest service roads, having blades secured in a real case beats the plastic clamshells that crack after one winter in the truck.
The Reality Check
Customer reviews paint a mixed picture. Common praise includes the variety of blades, convenient modular case, and universal fit compatibility. But contractors report blade teeth wearing faster than advertised in heavy metal use and limited lifetime for bi-metal blades when hitting nails.
That tracks with jobsite reality. No blade loves hitting nails, and Milwaukee’s aren’t magic. The value proposition hinges on whether you need premium performance often enough to justify the investment in a quality blade kit.
The Verdict
Milwaukee’s OPEN-LOK kit makes sense for full-time contractors who burn through blades and value organization. The carbide options handle the nasty stuff that destroys cheap blades, while the variety covers most oscillating tool tasks without multiple hardware store trips.
The kit includes no manufacturer warranty as a consumable accessory product, but it’s made in USA with global materials and requires no California Proposition 65 warning.
You’re paying for blade longevity and PACKOUT integration. If you’re already running Milwaukee’s modular storage system and hate changing blades mid-job, this kit delivers. If you’re doing occasional weekend projects, buy individual blades as needed.
