All of these tools are currently in the hands of the Tool Box Buzz professionals being evaluated on the job site to give you the best facts and our opinions so you can make wise purchase decisions

The Benefits of Flexvolt Advantage Technology

What is Flexvolt Advantage Technology ? DEWALT 20v tools now have the ability to run off 60v Flexvolt batteries providing us with more power than paired with the 20v batteries. You may be saying duh, but the power boost is substantial! The DEWALT Flexvolt Advantage Technology provides these new tools with a major power boost, giving us the ability to work them to their full potential. The DEWALT DCB573B 7-1/4″ Circular Saw gives the user over 75% more power when paired up with a 6.oAh Flexvolt battery.

What’s the Difference?

The difference in this saw vs the DEWALT 60V Flexvolt Circular Saw is very little. A couple of the noticeable items are the Flexvolt Advantage Technology’s saw has a silver blade guard and shoe plate where the Flexvolt saw is all black. The only other key difference is the ability to run on either 60v/20v or strictly on 60v.

What’s the Same?

These two saws are the same in weight and size. They both have the same industry-leading ergonomics, rafter hook, and onboard storage blade changing wrench. Both of these saws are the same cost which will be detailed below.

Using the DEWALT DCS573B on Site

We have been evaluating the DEWALT DCB573B on deck construction job sites. We ran the saw on both a 6.0Ah Flexvolt battery as well as the 20V 8.0Ah battery. There was a noticeable difference in power from one to the other. We started off cutting with the 60V and were able to make it the whole day on just one battery. After cutting forty 2″x10″ joists we switched over to the 20V to finish up the mid-span and picture frame blocking and noticed the decrease in power and speed. Once we cut a bunch of blocking we switched back to the 60V to complete the task.

Overall Impression and Cost

If considering purchasing this saw, you do not have to worry about which DEWALT platform you are on. You have the option to select either the 20v or the 60V Flexvolt platform. Need more power use the Flexvolt battery or simply need to make a few cuts pick the 20v battery. Having the option keeps the end-user from having to spend additional money on another battery.
