Electric ratchet (milwaulkee model # 2556-20 M12 12V Lithium-Ion FUEL 1/4″ Ratche) vs 90 degree Milwaukee 2667-20 M18 2-Speed 1/4″ Right Angle Impact

Hi,

I’ve recently been doing projects on my vehicles during the pandemic (2003 Honda CRV replaced front axles, lower arms, main bearings, ball joints, upper tie rod connection… 2016 4×4 SR5 Tacoma rear axle fluid, front diff. fluid, & trans axle fluid…. 2007 Toyota prius various assemblies and tune ups )… I purchased the milwaulkee 1/2″ square ring impact wrench to get the big bolts off and it works like a charm & it uses the same battery as my combo drill/impact driver set as well as my M18 multi-tool (2626-21).  I’m looking into getting a electric ratchet (https://www.farmandfleet.com/products/1106323-milwaukee-2556-20-m12-12v-lithium-ion-fuel-1-4-ratchet-bare-tool.html) and then saw the 90 degree 2667-20 M18 2-speed 1/4″ impact driver tool (https://www.cpomilwaukee.com/milwaukee-2667-20-m18-lithium-ion-1-4-in.-2-speed-right-angle-impact-driver–tool-only-/miln2667-20.html)  &  the 2668-20 impact wrench tool (https://www.cpomilwaukee.com/milwaukee-2668-20-m18-lithium-ion-2-speed-3-8-in.-right-angle-impact-wrench–tool-only-/miln2668-20.html) and since I lean toward tools using the same battery size I’m leaning toward the impact tools vs the rachet tool … I intend to use it when removing (i.e., not installing) spark plugs, small bolts 10mm thru 16mm bolts & not sure which one to choose (Ratchet vs impact).  For tight spaces probabley the impact wrench as I can attach my sockets directly to it.  I’m just not sure about the intended designs purpose for each of these designs.

Let me know what your experiences have been with these tools whether or not by Milwaulkee.

Thanks,

I have the m18 ⅜” right angle impact and the m12 ⅜” brushed (non-fuel) ratchet.  The impact is pretty underpowered at only 60ft/lbs of torque.  It is pretty compact but won’t break a lot of fasteners loose and then you’re stuck grabbing a wrench anyhow. The m12 ratchet, while having less torque can be used as a ratchet so you can break the fastener loose by hand and then use the power to run it off.  I also have the m12 right angle impact wrench, which has like 250ft/lbs of torque so it has a lot more power but the head is also not as compact.  I’m not a mechanic but I would think the ratchet would be best suited for engine bay work.
