Exchange-A-Blade EAB Bimetal Hole Saw 2″

Exchange-A-Blade’s 2-inch bimetal hole saw delivers over 70 cuts in 3/16” steel plate — far exceeding the 10-50 cuts typical of standard competitor bimetal hole saws. For contractors drilling through metal studs, electrical boxes, or plumbing rough-ins, that performance gap means fewer blade changes and less downtime. The M2 Professional-grade bimetal construction and heavy-duty 3/16” backing plate make this a workhorse tool, not budget filler.

Material-Specific Performance

Success with any hole saw depends on matching speed to material. Running too fast burns teeth. Too slow wastes time. Exchange-A-Blade provides exact RPM specifications:

Material	Maximum RPM
Wood	2000
Aluminum	255
Steel	170
Stainless steel	85

Those aren’t suggestions. Exceed them and watch your investment turn into scrap metal. The 1 3/8 inches cutting depth handles standard 2x4 framing and most electrical box installations in a single pass.

Construction That Solves Real Problems

The reinforced backing plate is specifically designed to reduce run-out on standard mandrels. Mandrel wobble ruins cuts and wastes material. That 3/16 inch heavy-duty reinforced plate keeps the saw tracking true, especially important when drilling overhead or at awkward angles.

The Professional-grade M2 teeth maintain sharpness longer than entry-level bimetal options. M2 steel holds its edge through repeated cuts in tough materials — the difference between changing blades twice a day versus once a week on metal-heavy jobs.

Exchange Program Economics

All EAB products are fully recyclable, supporting a circular economy model. More importantly for contractors counting costs, the saw is Part of the EAB Exchange program where users can return dull or damaged items to participating retailers for an exchange credit.

Western Building Center’s 11 Montana locations participate in this exchange system. Return your worn saw for credit toward replacements. The actual exchange value varies by condition, but it beats tossing dead blades in the scrap bin.

Frequently Asked Questions

What mandrel fits this hole saw? Use of a mandrel with a 5/8”-18 thread is standard for this size hole saw. The saw requires a standard hole saw mandrel/arbor (not included).

How does the M2 steel compare to standard bimetal? M2 Professional-grade Bimetal refers to the tooth material grade. Standard bimetal uses M3 or lower grades. M2 maintains hardness at higher temperatures, critical when cutting metal generates heat.

What materials can this cut? The saw handles Wood, Plywood, Lumber, Wood flooring, Particle board, Composites, Plastics, Laminate, Drywall, Vinyl tile, Ferrous metals (e.g., steel, stainless steel), Non-ferrous metals (e.g., aluminum).

What’s the actual cutting performance in steel? Testing shows over 70 cuts in 3/16” steel plate compared to 10-50 cuts typical of standard competitor bimetal hole saws.
