Overview
The DEWALT DCS378B is a 20V cordless saw with a 535 watt motor and 570 RPM blade speed, built with an alloy steel construction and an 8 inch cutting capacity.
DEWALT's 20V MAX platform covers everything from drills to saws, and the DCS378B slots in as a battery-powered cutting tool rated for 570 RPM. The 8 inch capacity figure and alloy steel build point to a saw meant for cutting metal stock such as pipe or rod rather than framing lumber. As with most bare-tool DEWALT listings, the battery and charger are typically sold separately.
- 20V MAX cordless power source
- 535 watt motor rated output
- 8 inch cutting capacity
Who it's for
This fits tradespeople and DIYers already invested in the DEWALT 20V battery system who need a portable saw for metal cutting jobs. It is not the right pick for someone starting from zero on batteries, since none is confirmed included in this listing.
Pros and cons
- Runs on DEWALT 20V MAX batteries
- 535 watt motor for portable cutting
- Alloy steel construction
- Battery and charger not confirmed included
- 570 RPM is slow versus a circular saw
- 8 inch capacity limits larger stock
Performance notes
A 535 watt motor spinning at 570 RPM is a low, steady speed compared to a circular saw, typical of a cutting tool built for control over metal rather than raw speed through wood. The alloy steel build adds durability for repeated cuts on site. The 8 inch capacity sets the upper limit on stock diameter or width this saw can handle in one pass.
