Exchange-A-Blade EAB Bimetal Hole Saw 2″
Tools Exchange-A-BladeExchange-A-Blade’s 2-inch bimetal hole saw delivers 70+ cuts in 3/16” steel plate: seven times what standard hole saws manage. The M2 Professional-grade Bimetal construction handles everything from drywall to stainless steel, built for Montana contractors running multiple jobsites far from supply centers.
The Exchange-A-Blade Difference
M2 bimetal teeth cut where others bind. Testing shows this hole saw punches through 3/16” steel plate over 70 times, while standard competitor bimetal hole saws manage 10-50 cuts. That’s real jobsite performance, not marketing fluff.
The 3/16-inch heavy-duty reinforced backing plate addresses the mandrel run-out problem that plagues cheaper hole saws. Less vibration means cleaner holes and longer tooth life. At 1 3/8 inches cutting depth, it handles standard 2x4 framing and thick-wall pipe in a single pass.
Material-Specific RPM Guidelines
Running the right speed extends blade life dramatically:
| Material | RPM | Notes |
|---|---|---|
| Wood | 2000 | Full speed for clean cuts |
| Aluminum | 255 | Slow prevents tooth loading |
| Steel | 170 | Low speed preserves teeth |
| Stainless steel | 85 | Crawl speed for hardest materials |
Exchange-A-Blade products are 100% recyclable, keeping worn tools out of landfills.
Who Should Buy This
Contractors cutting mixed materials daily get the most value. Plumbers drilling through floor joists, plates, and steel strapping. Electricians punching conduit holes through everything from drywall to steel studs. HVAC techs cutting ductwork openings.
The 2-inch diameter handles common trade sizes: standard electrical boxes, small pipe runs, hardware mounting. Strong buyer ratings across hundreds of reviews back up the specs.
Montana Contractor Considerations
Standard hole saw mandrels work fine: the reinforced backing plate is specifically designed to reduce run-out on standard mandrels. No special arbor required. The hole saw requires a mandrel with 5/8”-18 thread, which is standard for this size.
The Verdict
Exchange-A-Blade built a hole saw that cuts longer than the competition. The M2 teeth maintain sharpness longer than entry-level bimetal options, while the reinforced backing plate eliminates the wobble that ruins holes and burns teeth.
Not perfect for everyone. Homeowners cutting just a dozen holes may not need this level of durability. But for contractors burning through hole saws weekly, the proven 70+ cut durability in steel makes it a tool that earns its keep on commercial jobsites.
