Milwaukee 1/4" Hex vs High Torque Cordless Impact

[niferous]

I'm in the market for one of these and need a little help. The 1/4" hex cordless impact says that it has a max torque of 1600 foot pounds and 3600 blows per minute (full specs). The high torque cordless impact says it has a max torque of 450 foot pounds and 2700 blows per minute (full specs).

I want a cordless impact that can break loose highly torqued fasteners so it seems like the high-torque model would be the best choice. But looking at the specs the high-torque model isn't as high torque as the 1/4" hex model. On top of that the 1/4" hex model can be used to drill (the high-torque model has a 1/2" anvil), it's lighter, and it's about $140 cheaper.

I'm looking at the specs and can't seem to find any advantage that is making the high-torque model actually high torque, or worth the extra $140. Any ideas?

i think your reading things wrong 1/4 hex is 1600 inch pounds. quiet a big difference from a 1/2inch 18v impact.

1600 lb-in is equivalent to 133 lb-ft. For high torque applications (lug nuts, suspension fasteners, etc.) get the 1/2" drive impact wrench rather than a 1/4" hex impact driver. The Milwaukee M18 is a good one.

Yeah, gotta watch out for inch-pounds. Divide by 12 to get equivalent foot-pounds.

Dang it, I did totally miss that. Thanks for the clarification.
