Strengths & Weaknesses
What We Like
Variable-speed range for material control
Variable speed 0-3000 spm is available on the DEWALT DCS386B for precise cutting control. This 0–3000 spm range lets users slow the saw for metal and speed up for wood, improving cut quality and blade life. Carpenters and remodelers working mixed-material jobs gain the most from that control.
Generous 1-1/8 in stroke length
Stroke length of 1-1/8 in (28.6 mm) on the DEWALT Reciprocating Saw increases material removal per stroke. Greater per-stroke travel typically speeds demolition and pruning compared with compact 3/4 in tools, reducing cycle time. Demolition crews and landscapers who need faster cuts will notice the throughput difference.
FLEXVOLT power boost option
Up to 50% more power with FLEXVOLT batteries is claimed for the DCS386B Reciprocating Saw. That additional power supports tougher cuts and higher feed rates when paired with a 60V MAX DCB606 pack. Contractors who own FLEXVOLT packs benefit most from that extra torque and speed.
Brushless motor improves efficiency
Brushless motor with variable 0-3000 spm operation on the DCS386B reduces heat and service needs compared with brushed designs. Brushless systems typically provide better efficiency and longer runtime per battery ampere-hour under load. Tradespeople who run saws for many hours daily see reduced maintenance and operating cost.

Keyless lever-action blade clamp with variable 0-3000 spm operation on the Cordless 20V MAX reciprocating saw enables faster blade swaps between tasks. Faster blade changes cut downtime on multi-material jobs and remove the need for wrenches or hex keys. Renovators and emergency responders who change blades often benefit from the speed.
Integrated LED for low-light work
$165.90 tool-only price includes an integrated bright LED on this cordless reciprocating saw that helps visibility. On-site LED lighting aids alignment in attics, crawlspaces, and framed cavities where external lamps are awkward. DIYers and installers who work in low-light conditions gain safer, more accurate cuts.
Potential Drawbacks
Tool-only pricing requires extra purchases
$165.90 tool-only price for the reviewed DEWALT DCS386B reciprocating saw excludes battery and charger, increasing upfront cost. Buying a compatible battery, such as a 60V MAX DCB606 or a 20V DCB205, adds significant expense and weight to the kit. Budget-conscious buyers and first-time purchasers must factor battery and charger costs into total ownership price.
Limited technical documentation and missing runtime
Battery compatibility lists DCB606 (60V MAX) and DCB205 (20V MAX) for the DEWALT DCS386B, yet runtime per charge is not provided, which limits planning and usage. Specification for weight is not provided, which limits planning/usage for transport and site logistics. Project managers and rental houses need runtime and weight data before procurement or job scheduling.
Stroke length smaller than some demolition models
Stroke length 1-1/8 in is shorter than some demolition-class 1-1/4 in saws, reducing per-stroke removal volume. That 1/8 in difference can translate to slower gross material removal on heavy demolition compared with larger-stroke competitors. Heavy demolition contractors who prioritize raw removal rates may prefer larger-stroke models.
Performance depends on higher-voltage FLEXVOLT packs
Up to 50% more power is claimed with FLEXVOLT batteries, but 20V packs may deliver lower output on the DCS386B. Buyers expecting demolition-level performance from a 20V pack will need a 60V MAX DCB606 FLEXVOLT battery to reach higher power levels. Owners with only 20V batteries should plan to buy FLEXVOLT packs or select higher-voltage tools for maximum performance.

- Brushless motor
- An electric motor design used in this saw that omits carbon brushes, running cooler and more efficiently to deliver longer runtime, higher consistent power, and reduced maintenance compared with brushed motors.
- FLEXVOLT
- DEWALT's dual-voltage battery system that automatically provides higher-voltage output (up to 60V MAX) when paired with compatible tools like the DCS386B to increase cutting power and torque.
- 20V MAX
- DEWALT's 20-volt cordless battery platform designation indicating the saw can operate on standard 20V packs (like the DCB205) when a FLEXVOLT pack is not used.
- DCB606
- The DEWALT model number for a 60V MAX FLEXVOLT battery pack that, when used with the DCS386B, boosts peak power and torque for heavier demolition tasks.
- DCB205
- The DEWALT model number for a 20V MAX battery pack compatible with the DCS386B that provides standard 20V operation and generally longer runtime-per-charge for lighter tasks.
- Stroke length
- The distance the saw blade travels in one back-and-forth motion (1-1/8 inch on this model), which affects how aggressively and quickly material is removed per stroke.
- SPM (strokes per minute)
- A speed metric showing how many full blade strokes the saw makes per minute (0–3,000 spm for the DCS386B), where higher SPM typically means faster cutting in softer materials.
- Tool-only
- A sales format indicating this listing includes only the saw itself and does not include a battery or charger, so you must purchase compatible packs separately.
- Keyless lever-action blade clamp
- A tool-free blade retention mechanism on this saw that uses a lever to lock and release blades quickly for single-handed, fast blade changes on the jobsite.
- Bi-metal blade
- A common reciprocating saw blade construction (two bonded metals) recommended for cutting both wood and metal with the DCS386B because it balances toughness and flexibility.
