Milwaukee M18 vs Dewalt: A Comprehensive Comparison of Cordless Table Saws
In the market for a cordless table saw? Two power tool giants, Milwaukee and Dewalt, have thrown their hats into the ring with their M18 and DCS7485B models respectively. Both tools offer the convenience of cordless operation, but which one is the better choice? Let's dive into a detailed comparison to help you make an informed decision.
Power and Performance
The heart of any table saw is its motor, and both Milwaukee and Dewalt have packed impressive power into their cordless offerings. The Milwaukee M18 Fuel 8-1/4" Jobsite Table Saw (model 2645-20) is powered by a brushless motor that delivers up to 5,000 RPM, while the Dewalt DCS7485B 20V Max Cordless Tough System Table Saw offers up to 5,800 RPM. On paper, the Dewalt has the edge in terms of raw power, but let's see how this translates in real-world use.
Cutting Capacity
Both saws can handle a variety of materials, but the Milwaukee M18 has a slight advantage in cutting depth. It can handle stock up to 3-1/2" thick at 90 degrees and 2-1/2" at 45 degrees, while the Dewalt can handle up to 3-1/8" at 90 degrees and 2-1/4" at 45 degrees. This might not seem like much, but it could make a difference when working with thicker stock.

Design and Build Quality
Both saws are well-built and designed with durability in mind, but they have some key differences. The Milwaukee M18 has a more compact design, making it easier to transport and store. It also has a unique rack-and-pinion fence system that allows for quick and precise adjustments. The Dewalt, on the other hand, has a larger footprint and a traditional fence system. It also has a more robust stand, which can be an advantage when working on uneven surfaces.
Weight and Portability
The Milwaukee M18 is the clear winner when it comes to portability. It weighs in at just 52 pounds, making it one of the lightest cordless table saws on the market. The Dewalt, while still portable, is significantly heavier at 84 pounds. This could be a deciding factor if you're planning to move your saw around a lot.
Features and Accessories
Both saws come with a range of features designed to make your job easier. The Milwaukee M18 has a built-in dust port, a guard system that can be adjusted with one hand, and a unique "One-Key" system that allows you to track and manage your tools. The Dewalt, meanwhile, has a Site-Pro modular guarding system, a telescoping fence rail, and a ToughCase for storage and transportation.

Battery and Runtime
Both saws use 18V lithium-ion batteries, but the Milwaukee M18 comes with two 5.0Ah batteries and a charger, while the Dewalt comes with a single 4.0Ah battery and a charger. This gives the Milwaukee a significant advantage in terms of runtime, as you can run one battery while charging the other.
Price and Value
The Milwaukee M18 is the more expensive of the two saws, with a price tag that can be upwards of $500. The Dewalt, on the other hand, typically retails for around $300. However, the Milwaukee's included batteries and charger, as well as its superior portability and cutting capacity, make it a better value in our opinion.
Which Saw is Right for You?
The choice between the Milwaukee M18 and Dewalt DCS7485B ultimately comes down to your specific needs. If you're looking for a saw that's easy to transport and offers impressive cutting capacity, the Milwaukee M18 is the clear winner. However, if you're looking for a saw with more raw power and a more robust stand, the Dewalt might be the better choice.
