Milwaukee 2720-21 vs DeWalt DCS387: Which Saw for Contractors?

Milwaukee 2720-21 vs DeWalt DCS387: Power and Durability

The Milwaukee 2720-21 M18 Fuel 18-Volt Lithium-Ion Brushless Cordless Sawzall Reciprocating Saw Kit emphasizes power and harsh-use durability. Its POWERSTATE brushless motor (electronic commutation) and REDLINK PLUS electronics (tool protection) boost durability and resist overload. Reciprocating Saws like this kit trade sustained torque for heavier weight compared with compact machines. DeWalt DCS387, by contrast, leans toward lighter mass and easier maneuvering for finish and tight-access cuts.

Key 2720-21 technical specifications and included items

• Voltage: 18-Volt
• Motor: POWERSTATE brushless motor
• Electronics: REDLINK PLUS intelligence (tool protection)
• Battery included: M18 REDLITHIUM XC 4.0 (pack included)
• Charger included: M18 and M12 Multi-Voltage Charger
• features: adjustable shoe, integrated LED light, rafter hook

How do motor design and brushless advantages change jobsite performance?

Milwaukee 2720-21 delivers faster cuts and longer runtime under heavy demolition workloads. A brushless motor uses electronic commutation rather than carbon brushes, which improves efficiency and durability. This design lowers internal friction and heat, which increases runtime per battery charge. DeWalt DCS387 matches some brushless benefits while often prioritizing lighter packaging and tighter ergonomics.

Selecting the Best Cordless Circular Saw for Jobsite Productivity

The Milwaukee 2720-21 M18 Fuel 18-Volt Lithium-Ion Brushless Cordless Sawzall Reciprocating Saw Kit prioritizes continuous cutting power. Contractor productivity requires predictable runtime, quick blade changes, and durable shoes for accurate plunge and demolition cuts. Compact models trade torque for lower weight, and that weight saving helps in overhead or confined-space tasks. For crews handling long demolition runs, a heavier tool with higher torque usually finishes faster and reduces total passes.

When should contractors choose a compact saw versus a full-size model?

DeWalt DCS387 provides compact handling for tight access and finish work. Use DCS387 when you need one-handed maneuvers, faster repositioning, and less operator fatigue. The Milwaukee Reciprocating Saw (Sawzall) sacrifices portability but adds stroke and torque for thicker materials. Stroke refers to blade travel per cycle, which increases material removal and reduces the number of passes required.

Milwaukee 2720-21 vs DeWalt DCS387: Batteries and Service Costs

The Milwaukee 2720-21 M18 Fuel kit bundles an M18 REDLITHIUM XC 4.0 pack. The 4.0 marking denotes Ah (ampere-hour) capacity, indicating stored energy per charge. DeWalt DCS387 works with the 20V MAX ecosystem, which often helps owners leverage existing batteries to lower lifetime costs. Warranty coverage and the availability of authorized service centers affect real ownership costs more than small initial price differences.

Battery and service cost comparison points

• Milwaukee: bundled M18 REDLITHIUM XC 4.0 Ah battery (kit value included)
• Charger: M18 and M12 Multi-Voltage Charger included with Milwaukee kit
• Manufacturer claims: Milwaukee asserts up to 2 runtime and 5 tool life versus competitors (manufacturer claim)
• DeWalt: 20V MAX battery platform compatibility can reduce incremental battery purchases for existing owners
• Service networks: both brands maintain broad U.S. service coverage, but local dealer practices vary

What maintenance practices reliably extend battery life and minimize downtime?

2720-21 Reciprocating Saw benefits from storing batteries at 40-60 charge to prolong capacity. Park batteries away from heat above 100 F and avoid repeated deep discharges between uses. Use the supplied M18 and M12 Multi-Voltage Charger for temperature-managed charging when available. Rotate packs across tools, label charge cycles, and keep a 1:3 spare-to-used ratio to prevent avoidable downtime.
