Is there really a big difference between these two crank pullers?

I want to remove an ISIS crankset (FSA Carbon Pro Track), but would really like it if the crank puller was compatible with square taper cranks as well, if possible.

Any help is appreciated... I've always been confused by all the different tools offered by Park.

3 sizes in the thread in crank-arms, patterned after Campag, [most],
TA, the Cyclo-tourist, , and uniquely, Stronglight, older ones..

The ISIS spindle is much wider than square taper, with a pretty large hole in the middle. A crank puller sized for a square taper spindle would likely destroy an ISIS spindle.

They do make universal tools, with both sizes: https://www.amazon.com/Park-Tool-Comp...ef=pd_sbs_sg_4

Park tool site can help you with the tool you need for your particular crank. The Park ccp-22 is for square taper cranks. But better yet is that Park sells a tool called the Universal Crank Puller that works for both square tape and splined cranks and it works by attaching the tool to the bolt then an adjustable wrench or the right size box wrench to the tool then use; this way you'll have one tool for both style of cranks. https://www.parktool.com/product/univ...d-cranks-cwp-7

Awesome! Thanks everyone. I've used a CWP7 (or similar) at the bike co-op before... I'm not sure why I didn't think to look one up earlier.
