Dewalt Battery Cut-Off Saw | Models Compared

The Dewalt DCS692B 60V MAX 9-inch Brushless Cordless Cut-Off Saw is the flagship battery-powered model for cutting concrete, rebar, and steel, running off a single FLEXVOLT battery.

When you’re looking for a Dewalt battery cut-off saw, the lineup can get confusing fast. Between the 60V flagship, the legacy model, the upcoming POWERSHIFT behemoth, and the compact 20V tool, each one serves a completely different job. This article breaks down every current Dewalt cordless cut-off saw, what each actually cuts, and which one belongs in your trailer.

Understanding the Dewalt Battery Cut-Off Saw Lineup

Dewalt currently sells four cordless cut-off saws that span three battery platforms. The DCS692B is the primary 60V model — it replaced the earlier DCS690B with a brushless motor and a water-ready guard. At the small end, the DCS438B runs on 20V batteries and handles light trimming, not heavy demolition.

Each model uses a different battery system, so the platform you already own often decides which saw makes sense. The 60V FLEXVOLT batteries work in Dewalt’s 20V tools too, but the reverse isn’t true — 20V packs won’t power the 60V saws.

DCS692B vs DCS690B: What’s The Difference?

The DCS692B replaced the DCS690B as Dewalt’s current 60V cut-off saw. The main upgrade is the brushless motor, which runs cooler and delivers more runtime per charge than the older DCS690B’s brushed design. Both saws share the same 9-inch blade, 3-1/4-inch depth of cut, 6,600 RPM no-load speed, and 10.85-pound bare weight.

Both models use a 7/8-inch arbor, accept standard 9-inch diamond blades, and include a 5-position rotatable guard. The DCS692B adds a water connection valve for wet cutting to control dust — a feature that matters if you cut concrete indoors or near finished work.

Pricing sits close: the DCS692B tool-only runs $619, while the remaining DCS690B stock sells at $579.99. The extra $40 buys the brushless motor and water valve, which most buyers find worth it.

The 2026 POWERSHIFT Model: What We Know So Far

Dewalt unveiled the DCPS612AG2 12-inch cut-off saw at World of Concrete in January 2026, with retail availability expected in November 2026.

If you regularly cut thick concrete or need clean deep passes without flipping the material, the POWERSHIFT model will outperform the 60V saws by a wide margin. The downside is platform lock-in — the battery and charger are separate from any existing Dewalt system, and pricing hasn’t been announced yet.

When To Choose The 20V DCS438B Instead

The DCS438B is a 3-inch cut-off tool, not a replacement for the 60V saws. It cuts up to 7/8 inch deep and handles plastic, thin metal, and soft metals. An LED light illuminates the cut line, and it’s compatible with a dust extractor. Use it for trimming bolts, cutting conduit, or scoring tile — not for thick rebar or concrete pavers. It runs on Dewalt’s 20V MAX XR batteries, so if you already own those, this is a lightweight add-on for finish work.

How To Use A Dewalt Battery Cut-Off Saw Safely

Cut-off saws spin at 6,600 RPM — a blade bind at that speed creates serious kickback force. Follow this sequence every time:

1. Wear full PPE. Eye protection, hearing protection, and heavy gloves are mandatory. Use a respirator for dry cutting concrete.
2. Mount the blade correctly. Secure a 9-inch diamond blade on the 7/8-inch arbor for the DCS692B. Verify the blade’s rated RPM exceeds the saw’s 6,600 RPM no-load speed.
3. Set the guard. Rotate the 5-position guard so the exposed blade covers only the arc needed for the cut depth.
4. Connect water for wet cutting. Attach a hose to the valve to suppress concrete dust and keep the blade cool. Never use an open water source without the valve — leaks can damage the motor.
5. Cut with steady pressure. Let the blade do the work. Forcing the tool into the material causes blade binding and kickback. Release the trigger and let the blade stop completely before setting the saw down.

Reverse the blade direction when cutting metal to direct sparks away from your body, and always confirm the material is clamped or supported so the cut doesn’t pinch the blade.

Common Mistakes To Avoid

The most frequent error is using the wrong tool for the material. The 20V DCS438B only cuts 7/8 inch deep — it stalls immediately on thick concrete or rebar. On the 60V saws, skipping the water connection on concrete work shortens blade life sharply and creates heavy silica dust. Another common mistake is installing a non-diamond blade on the 9-inch cut-off saw; the arbor accepts standard diamond blades, and using an abrasive wheel designed for a different tool is unsafe.

Which Dewalt Battery Cut-Off Saw Should You Buy?

Start with the thickest material you cut regularly. If it’s rebar, concrete pavers, or scoring slabs up to 3-1/4 inches deep, the DCS692B is the right call — it’s the current 60V model with the brushless motor and water connection, and at $619 for the bare tool, it undercuts every gas-powered alternative in weight and maintenance. If you already own FLEXVOLT batteries, the kit version DCS692X2 saves you from buying a charger and a second pack.

If you need deeper than 3-1/4 inches or cut heavy concrete all day, wait for the DCPS612AG2 POWERSHIFT saw in November 2026. It’s a different class of tool — heavier, more expensive, and on a separate battery platform, but it delivers cuts no cordless Dewalt has reached before.

For light-duty trimming, conduit cutting, or scoring tile, the 20V DCS438B is a fraction of the size and weight, and it shares batteries with the rest of your 20V kit.
