Which cordless impact gun?

[arbwork]

   we tried the   Makita DTW1001RTJ with a   Nut Busting Torque: of  1700 Nm recently to undo the chipper blade bolts and it did not have the toque to undo them, it has a tightening toque that matches manufactures tightening spec and therefore looked as if it would help speed up blade changes. we have a Makita DTW 450 that's saves us lots of time with the smaller more normal jobs

 

now trying to get qet a  demo of the Milwaukee M18 to see if this will crack the bolts, any suggestions welcome

Original thought came from taking the wheels off the Wench's Mini, wondered how she would manage. Thought about getting one to leave in the garage for when I'm fettling, so more domestic use than serious things like truck wheels etc. I could go Air, as there is a compressor int'garage!

I would go air because it only takes a couple of minutes to fill tank as it can take 30mins to charge battery.

I have a Clarke 24v cordless one. Abit bigger than I'd like but haven't come across anything it won't budge from cranķ bolts, rsj fixing etc

My 1/2 Milwaukee M18 is good. Not sure if it will crack chipper knives as you can only get it on the allen key side on the bolt head. This is on a bandit 75. I know it shreds the bolt head before the knife undoes, we just crack the bolt side with a breaker bar. and wind it off with an allen key in the impact gun. I imagine these are about 400ftlb when you try to undo them, they seem to tighten with use. 

 

Milwaukee sell a 3/4 inch drive one with some big numbers which might be better suited to your big chippers. 

 

The 1/2 inch spits wheelnuts off in about 1 second and I use it a lot for F1 style pitstops taking the outer wheels off the HB20 grinder. Saves no end of time on that job. 

 

I think Makita may be lying slightly with their specs. I've seen mine against makita and snapon equivalents and the milwaukee is the best, the snapon is the nicest to use but the milwaukee I would say is a fair bit more powerful than either. Though the specs would suggest its the least powerful.

Another vote for Milwaukee M18, I've not yet found an M18 tool that doesn't impress (the cordless mag drill is also very good).
