Who is the DeWalt DCS379B Hacksaw For?
This hacksaw is designed for professionals and serious DIYers who need a portable, cordless solution for cutting metal. It excels in plumbing, electrical, and HVAC work where access to power outlets is limited. The brushless motor provides the torque needed to cut through steel pipe, conduit, rebar, and threaded rod efficiently.
Performance and Cutting Capability
Owner reviews from major retailers consistently praise the DCS379B for its cutting speed. The 1-1/8 inch stroke length allows for aggressive cuts without bogging down. The variable speed trigger, ranging from 0-3,200 SPM, gives the user control for different materials. Many users note that it cuts through 2-inch steel pipe in under 10 seconds with a fresh 5Ah battery.
Build Quality and Durability
DeWalt is known for its rugged construction, and the DCS379B is no exception. The housing is made from high-impact plastic with rubber overmolding for a secure grip. The metal shoe is adjustable for bevel cuts and provides stability. The keyless blade clamp is robust and holds blades securely, a common point of failure on cheaper saws.
Battery Ecosystem and Runtime
As part of the DeWalt 20V MAX system, this hacksaw benefits from a wide range of battery sizes. For heavy use, a 5Ah or 6Ah battery is recommended to avoid frequent swaps. Users report cutting over 100 feet of 1-inch conduit on a single 5Ah charge. The brushless motor is significantly more efficient than the brushed DCS374B, offering up to 50% more runtime.
Alternatives to Consider
If you are on a tighter budget, the DeWalt DCS374B is a capable brushed option that works with the same batteries. For those who rarely cut metal and want a tool for a stationary workshop, the corded DeWalt DW660 is lighter and costs less upfront. Competitors like the Milwaukee M18 Hackzall are lighter but have a shorter stroke length, making the DeWalt better for thicker materials.
What to Check Before Buying a Hacksaw
Consider the type of material you will cut most often. A longer stroke length (1-1/8 inch) is better for thicker pipe, while a shorter stroke is fine for thin metal. Check the blade compatibility; most DeWalt hacksaws use standard 1/2-inch universal blades. If you already own DeWalt batteries, a bare tool purchase is the most cost-effective route.
Mistakes to Avoid
Do not buy a brushed model if you plan to use the saw daily; the brushless motor pays for itself in runtime and longevity. Avoid using a small battery (like a 1.5Ah) for heavy cutting, as it will drain quickly and may not provide enough power. Always use a sharp blade designed for the material you are cutting to prevent binding and motor strain.
FAQs
