The best portaband saw for most buyers in 2026 is a deep-cut, brushless, 5×5-inch-capacity cordless model — specifically the Milwaukee 2729S-22 or DeWalt DCS374B — because 5-inch throat capacity is the dividing line between saws that can handle 2-inch angle iron and full EMT bundles in one pass, and those that force you to flip stock and cut twice.

What Actually Separates These Saws: The Numbers That Matter
Portable band saws (portabands) are marketed on voltage and kit contents, but three specs determine what a portaband saw can really do on steel: throat depth (cutting capacity), strokes/blade feet per minute, and blade life per battery charge on common jobsite stock.
- Throat depth: Standard saws offer 4-3/4″ to 5″ x 5″ capacity. Compact models drop to 2-1/2″ or 3-1/4″. If you regularly cut 2-inch angle iron, unistrut, or bundled conduit, only the deep-cut class clears it in one pass.
- Blade speed: Steel cutting wants 200–350 surface feet per minute (SFPM); faster speeds burn through bimetal blades on thick stock. Variable-speed triggers matter more than headline RPM.
- Weight: Deep-cut cordless models run 12–15 lbs bare. Overhead cuts on EMT make that pound difference felt by the third hour.
Head-to-Head: 2026 Deep-Cut Cordless Portabands
| Model | Cut Capacity | Weight (bare) | Blade Length | Platform | Best For |
|---|---|---|---|---|---|
| Milwaukee 2729S-22 M18 Fuel | 5″ x 5″ | ~12.9 lbs | 44-7/8″ | M18 | All-around trades, highest cut count per charge |
| DeWalt DCS374B 20V Max | 5″ x 4-3/4″ | ~12.4 lbs | 44-7/8″ | 20V Max / FlexVolt | DeWalt fleets; slightly lighter frame |
| Makita XBP02Z 18V LXT | 4-3/4″ x 4-3/4″ | ~14.3 lbs | 44-7/8″ | 18V LXT | Quiet operation, Makita fleet owners |
| Milwaukee 2829 M18 Fuel Compact | 3-1/4″ x 3-1/4″ | ~8.9 lbs | 35-3/8″ | M18 | Overhead conduit work, tight quarters |
| DeWalt DCS377B Atomic Compact | 2-1/2″ x 2-1/2″ | ~6.8 lbs | 27-1/2″ | 20V Max | Single-stick EMT, threaded rod, one-hand cuts |
How They Perform on Real Stock
EMT Conduit (1/2″ to 2″)
Every saw here cuts EMT easily — thin-wall steel is the least demanding task. The real variable is bundle capacity: a 5×5 throat swallows a 4×4 bundle of 1/2″ sticks (around 20 pieces), while compact 2-1/2″ saws top out at 4–6 sticks or single-stick work. On bundles and overhead runs, the compact Milwaukee 2829 wins on fatigue: at under 9 lbs with battery it can be held one-handed at shoulder height, where a 14-lb deep-cut cannot.
Rebar (#4 to #6)
Rebar separates blades, not saws. All three deep-cut models will cut #5 rebar in roughly 15–25 seconds at moderate speed with a 14/18 TPI bimetal blade. Where they differ: Milwaukee and DeWalt’s brushless motors hold speed under load better, which keeps teeth from stalling and glazing — the main cause of early blade death. Expect roughly 40–80 cuts on #5 rebar per quality blade before tooth wear slows cutting noticeably.
2-Inch Angle Iron (1/4″ Wall)
This is the deep-cut saws’ purpose. A 2″ angle leg plus 1/4″ wall means you want the full 5″ throat for clean positioning and the torque to keep the blade moving. The Milwaukee 2729S and DeWalt DCS374 handle this routinely; the Makita XBP02 does it but its slightly smaller capacity leaves less room to angle the work. Compact saws cannot complete this cut — don’t buy one for fabrication work.
Decision Matrix: Match the Saw to Your Work
| Your Situation | Recommended | Why |
|---|---|---|
| Electrician, mostly conduit, overhead daily | Milwaukee 2829 or DeWalt DCS377B compact | Weight beats capacity; EMT never needs 5″ throat |
| Fabricator / ironworker, angle iron and flat bar | Milwaukee 2729S or DeWalt DCS374B | 5″ capacity cuts 2″ angle, channel, and bundles in one pass |
| General contractor, mixed stock, occasional use | Deep-cut model matching your existing battery platform | Battery compatibility outweighs minor spec differences |
| Budget-limited, light home-shop use | Corded portaband (DeWalt DWM120 class, $150–250 range) | Unlimited runtime; cordless premium isn’t justified for occasional cuts |
Ownership Realities: Blades, Wear, and Cost Per Cut
The saw is the cheap part. Blades are the running cost, and most premature failures are user error:
- TPI selection: Rule of thumb — keep at least 3 teeth in the material. Thin EMT wants 18–24 TPI; rebar and angle iron want 10–14 TPI. Using a fine blade on thick stock is the fastest way to strip teeth.
- Blade math: A quality 44-7/8″ bimetal blade runs roughly $8–15. At 60 cuts on #5 rebar, that’s about $0.15–0.25 per cut — but drop to 15 cuts from running too fast, and you’ve tripled your consumable cost.
- What wears first: Rubber guide tires (the blade rides on them) and blade guide bearings. Inspect both every blade change; wobble in a guide bearing ruins new blades quickly.
- Battery draw: Deep-cut saws on thick steel drain a 5Ah pack in roughly a session of heavy cutting. Keep a second pack for fabrication days.
FAQ
Cordless or corded?
Cordless dominates jobsites in 2026 — cut quality is equivalent, and corded models only win on price and unlimited runtime for fixed shop setups.
What blade should I buy first?
A 14/18 TPI variable-pitch bimetal blade handles EMT, rebar, and angle iron acceptably. Stock dedicated 10–14 TPI blades once you’re cutting thick stock regularly.
Can a compact portaband replace a deep-cut?
Only if your largest stock fits the throat — check the diagonal, not just the listed capacity. A 2-1/2″ saw cannot make a 2″ angle iron cut regardless of blade or technique.
