18-Volt to 20-Volt MAX Lithium-Ion Battery Adapter Kit (2-Pack)

Cant get the primary screw off to install the blade. Way too tight. Ever hear of keep it simple...

I am very happy with the tool itself, but Home Depot shouldn’t deliver power tools in the DeWalt box, the likelihood of it getting stolen was astronomical, with that said, I shop Home Depot regularly, and will continue, but when customers order expensive things, you should put them in a generic box, that won’t make it as much of a target please

Easy to use and cuts smoothly and easy adjustments for angle cuts

This circular saw is light and powerful. I like that the 20 volt batteries are interchangeable between devices. My Dewalt chainsaw 20 volt 5.0Ah battery fits my Dewalt circular saw.

This was a graduation gift for my son he didn't want a ring so I gifted him some awesome dewalt tool!

I got this for my son . But I've been using it more ! So guess will have to buy another one!

Product works great. Very light and easy to install blade and use.

I love it, to convert 18vt to 20vt its great.

Works great

I purchased a full set of DeWalt 18v power tools more than a few years ago and, overall, they have served me well. However, when the 20v DeWalt line came out I thought that eventually I would eventually have to replace all my 18v tools. Voila, DeWalt solved my dilemma by producing an adapter system. So I gave it a try. Wow, the battery lightens the tools considerably and, in my experience, the charge on the new LI batteries lasts longer than the old 18v NiCads. I have used the adapter in all my drills, saws, impact wrenches, etc. without fail. DeWalt does not recommend using the new battery system in one tool I have, the DC970 Drill in which I still use the 18v battery, so when purchasing the adapter system it would be wise to check on whether your tools will work with the 20v adapter system. Yes, the locking tabs on the adapter were a little stiff at first but not so much so that it was a problem and, with use, the adapter installs and uninstalls easily. I have never had a problem with battery discharge but, then again, I make sure my tools are in the safe (off) position unless they are in use and at the end of the day, I remove the battery from each tool and then I remove the adapter from the tool as well (if you install and remove the adapter without the battery in place, you will find it much easier to mount and dismount the adapter). As shown in the photo, I have purchased 3 sets of 20v adapters and 6 batteries which allows me to keep working with multiple tools and I have yet to run out of power (although I sometimes have to wait to the battery to cool down before I put it into the charger).
