DeWALT DCF510:
Max Torque: 75 ft-lbs
Max Speed: 300 RPM
Included Anvils: 3/8 in. & 1/2 in. Square
Best For: Suspension, large bolts, high torque

DeWALT DCF520:
Max Torque: 50 ft-lbs
Max Speed: 450 RPM
Included Anvils: 3/8 in. & 1/4 in. Square, 1/4 in. Hex
Best For: Engine work, interior, speed

The main difference between these two ratchets is the balance of power versus speed. The DCF510 is designed for heavy-duty torque, while the DCF520 is DeWALT's highest speed 20V ratchet, optimized for clearing long fasteners quickly.

Which one should you choose?

Choose the DCF510 if you need raw strength. With 75 ft-lbs of torque, it is better suited for the stubborn bolts often found in suspension work or the undercarriage of your Buick. It handles larger 1/2-inch drive sockets natively.
Choose the DCF520 if you prioritize speed in tight spaces. At 450 RPM, it is 50% faster than the 510B. It is ideal for 1/4-inch and 3/8-inch fasteners in engine bays or interior work where you have lots of thread to travel but don't need massive torque to break things loose.

My bad, I was going by Home Depot's site. It isn't listed as an XR.
If you're a vet or military you can get it for $170 and no tax from shopmyexchange.com using their Home Depot hub.

This is the larger 3/8 and 1/2" tool with 75ft/lbs of the torque, the 520 is smaller 1/4 and 3/8 with only 50ft/lbs of torque. two different tools

Nobody can answer that but you. I listed their pros and cons, their attachment sizes, their strengths and weaknesses, their speeds and torque, you need to know what type of work you will be doing...

its like asking "do I need a Ferrari or a land rover?" without telling us what you are trying to do...

what size nuts and bolts? How rusty? how many? how fine pitch? how long are the threads? What sockets and head sizes are you mostly working with?
Only you can make this decision.

Mostly 10mm 12mm 17mm. not long. Brake jobs. Remove and replace components. I did a starter once and that bolt was a nightmare to take out.

My vehicle is very rusty. 2004 with 258K miles currently. All bolts that I've taken out recently has been tossed out and replace with new Honda bolts. I would not be comfortable putting them back into the vehicle as they were very difficult to take out.

So you need the model that is on sale right now to help with those older bolts and nuts. You need the torque more than you need speed.

I have this 510 model, when paired with a powerstack 1.7mah battery its very small and has plenty of power, and can fit in small spaces. Very nice!

I like the Milwaukee more, as someone that owns all Dewalt stuff and just the Milwaukee M12 highspeed ratchet. Between these, go high speed. These aren't made for breaking bolts loose unlike what someone else said, 75ft/lbs isn't going to break free stubborn bolts. These are more for like, doing a valve cover/oil pan/crank case or clutch cover type stuff on small engines/interior fasteners, basically places where you have a bunch of fasteners to undo at once. For breaking free stubborn fasteners, you need an impact gun.

I'm bought into the ecosystem but I can't help think how Milwaukee's are just much more compact.

Inaccurate information. This is definitely a XR version.
