Chicago Pneumatic CP7748 vs CP7736

[visedog]

I found two 1/2" Chicago Pneumatic impact wrenches on Amazon.in (CP7748 and CP7736). CP7736 has a peak torque of 900 N-m and costs about $165 here, while CP7748 is 1250 N-m and $277. My question is to somebody who has used both wrenches: is the additional torque of CP7748 worth spending $112 more? Did you notice any difference between the two wrenches in normal usage? It will help me in deciding which one to order.

Thanks for the reply!
