DEWALT DCS380B 20V MAX* Reciprocating Saw (Tool Only)

The Cordless Recip Saw That Goes Everywhere and Cuts Everything

The DEWALT DCS380B 20V MAX Cordless Reciprocating Saw is the go-to demo and cutting tool for electricians, plumbers, HVAC techs, remodelers, and general contractors who need a reliable saw that transitions from overhead pipe cuts to flush wall cuts to aggressive demo work — all on a single battery charge. With a 1-1/8-inch stroke length, up to 3,000 SPM, and a keyless 4-position blade clamp, the DCS380B is built to cut fast, change blades without stopping, and hold up across thousands of job-site hours.

Key Features & Benefits — Why the DCS380B Stays on Every Tool Belt

• 4-Position Keyless Blade Clamp → Flush Cuts, Overhead Cuts, Any Orientation: Rotates the blade to standard, teeth-up, horizontal left, and horizontal right positions — no tools required. Which means: one saw handles every cutting angle you encounter without stopping to swap tools or accessories.
• 1-1/8-Inch Stroke Length + 0–3,000 SPM → Fast Aggressive Cutting: The combination of long stroke and high SPM is what separates a true demo saw from a utility cutter. Which means: more material removed per stroke, fewer passes, and faster job completion on rough-in and demo work.
• Variable Speed Trigger → Precision When You Need It: Full 0–3,000 SPM range via trigger pressure gives you slow, controlled starts into pipe or drywall and full-throttle demo speed when you need to push through lumber. Which means: the same saw that demolishes a wall in minutes makes clean, controlled cuts in finish work without tearout.
• Electric Brake → Instant Stop on Trigger Release: The blade stops immediately when you release the trigger — not after coasting to a stop. Which means: safer cuts close to surfaces, faster repositioning, and significantly reduced risk of unintended contact after the cut is complete.
• Pivoting Adjustable Shoe → Longer Blade Life + Better Control: Advance the shoe position as the blade wears to distribute cutting action across the full blade length. Which means: you get substantially more cuts per blade before it needs replacing — a direct reduction in consumable cost over a project lifecycle.
• Double Oil-Sealed Shaft → Built for Dirty Conditions: The reciprocating shaft is sealed against dust, drywall particles, wood chips, and moisture contamination. Which means: consistent performance on dusty demo sites without premature shaft wear or bearing failure.
• Rubber Overmolded Comfort Grip → Reduced Fatigue on Long Cuts: The full-grip overmold absorbs vibration and provides secure hold even in wet or dusty gloved-hand conditions. Which means: less hand fatigue during overhead work and extended cutting sessions.
• 20V MAX + FLEXVOLT® Compatible → Maximum System Flexibility: Works with every DEWALT 20V MAX battery — compact 2.0Ah to high-capacity 8.0Ah — and accepts FLEXVOLT® 60V MAX batteries in 20V MAX mode for extended runtime on the most demanding jobs. Which means: if you're already in the DEWALT 20V MAX ecosystem, the DCS380B is plug-and-play from day one.
• 6.0 lbs. Bare Weight + 18 in. Length → Balanced for One- and Two-Handed Work: Not the lightest recip saw on the market, but well-balanced for sustained overhead use and one-hand control in tight mechanical spaces. Which means: less wrist fatigue when cutting pipe runs or trimming studs from a ladder.

How to Use the DEWALT DCS380B Reciprocating Saw

1. Select and install your blade: Pull the keyless lever-action blade clamp up, insert a universal-shank blade in the desired orientation (standard, teeth-up, or horizontal), and release the lever to lock. Give the blade a gentle tug to confirm it is secured before cutting.
2. Set the shoe position: Loosen and slide the adjustable shoe to the appropriate depth for your material. For thick material, push the shoe close to the blade base for maximum stroke use. For flush cuts, retract the shoe so it rests flat against the surface.
3. Choose your blade orientation for the cut: For overhead pipe or conduit cuts, rotate the blade to the teeth-up position. For flush cuts close to floors or walls, use the horizontal blade positions. For standard cuts, use the default downward-teeth orientation.
4. Install your 20V MAX battery: Slide a fully charged battery into the base until it clicks. Check the battery fuel gauge — LEDs should show at least two bars before beginning heavy cuts.
5. Begin cutting: Press the shoe firmly against the workpiece before pulling the trigger — this reduces vibration and prevents the saw from "walking" at the start of the cut. Apply light forward pressure; let the blade do the work. Do not force the saw.
6. Use variable speed for controlled entry: Start at low trigger pressure (slow SPM) to score a starting groove in metal or pipe, then gradually increase to full speed once the blade is tracking in the cut. This prevents blade walk and extends blade life.
7. Release trigger to stop: The electric brake engages immediately on trigger release. Wait for full blade stop before repositioning or changing blades.

Safety note: Always secure the workpiece before cutting. For cutting near energized electrical systems, confirm power is isolated before making any wall or ceiling cuts. Wear ANSI-rated eye protection and hearing protection when operating reciprocating saws.

Pro Hacks & Power-User Tips

• Rotate your blade position before it wears out, not after: When you notice slower cutting or increased resistance, advance the shoe 1/4 to 1/2 inch rather than immediately replacing the blade. Most users only use the first inch of blade life. Rotating the shoe position can double or triple effective blade life per set.
• Use the teeth-up position to cut pipe from below without marking the ceiling: In mechanical rough-in work, flipping the blade teeth-up lets you cut copper or PVC pipe from below in ceiling joist bays without dragging the saw body against the drywall above.
• Plug in a FLEXVOLT® battery for all-day demo: On full-day demolition jobs — opening walls, cutting floors, or ripping out framing — a DEWALT FLEXVOLT® 60V MAX battery running in 20V MAX mode delivers significantly more runtime than standard 20V packs, reducing battery swap time throughout the day.
• Use a bi-metal blade for nail-embedded lumber: Standard wood blades will shatter on nails. A 10-TPI bi-metal blade — rated for "wood with nails" — cuts through embedded fasteners, old decking, and demolition lumber without blade failure. This is the single most important blade choice for demo work.
• For pipe cuts, start slow to track the blade: On copper, galvanized, or ABS pipe, begin at the lowest trigger speed to score a starting groove in the pipe wall. Once the blade is seated in the groove, increase to full speed. This prevents blade skip and the dangerous lateral movement that comes with it.
• Make pocket cuts in drywall by plunging the blade tip: To open a wall for an outlet box or inspection without a starting hole, tip the saw at 45 degrees with the blade just touching the surface, then pivot the saw upright as you pull the trigger. The plunge technique is faster than drilling a starter hole and leaves a cleaner edge.
