Okay before we get started, we are not doing a head to head to see which tool is better. \u00a0We are just comparing the two tools to help you understand the differences between a full size and compact wrench. \u00a0Plus to cover some other items that may be helpful when you are looking for a cordless impact wrench. \u00a0If you are not familiar with an impact wrench, here is a good overview from\u00a0Wikipedia.<\/p>\n

“In operation, a rotating mass (the\u00a0hammer) is accelerated by the motor, storing energy, then suddenly connected to the output shaft (the\u00a0anvil), creating a high-torque\u00a0impact. The hammer mechanism is designed such that after delivering the impact, the hammer is again allowed to spin freely, and does not stay locked. With this design, the only\u00a0reaction force\u00a0applied to the body of the tool is the motor accelerating the hammer, and thus the operator feels very little torque, even though a very high peak torque is delivered to the socket. “<\/p>\n

This is a comparison between the Milwaukee High Torque Impact Wrench<\/a> (2663-22) and the Milwaukee Compact Impact Wrench<\/a> (2652-22). \u00a0Okay let’s get started with some of the similarities between the two tools.
\nObviously they are both Milwaukee tools. \u00a0Which means both are backed by a 5 year warranty. \u00a0Milwaukee makes some of the best impact wrenches on the market, just talk to anyone who owns one and we are confident you will get the same answer.<\/p>\n

    \n
  1. Volts<\/strong><\/span> – Both tools use the Milwaukee Red Lithium M18 batteries. \u00a0Also both kits come with two high capacity XC batteries and a charger.<\/li>\n
  2. Motor Layout<\/strong><\/span> – Both wrenches are built around a 4 pole frameless motor. \u00a0A 4 pole motor can produce more torque than a 2 pole configuration. \u00a0If you are looking for a tool with high torque and lots of power, the 4 pole frameless motor is probably the best on the market.<\/li>\n
  3. Anvil Size<\/strong><\/span> – Both wrenches use a 1\/2″ anvil. \u00a0While the type of anvil is different, the size is the same.<\/li>\n<\/ol>\n

    \"\"<\/a><\/p>\n

     <\/p>\n

     <\/p>\n

    Well that was easy. \u00a0That is pretty much all they have in common. \u00a0Same manufacturer, warranty, motor design, anvil size and volts. \u00a0Let’s see how these are different.<\/p>\n

     <\/p>\n

     <\/p>\n

      \n
    1. Anvil<\/span><\/strong> – As noted both are 1\/2″ anvils, but if you look closely, they are actually different. \u00a0The compact uses a detent pin while the high torque uses a friction ring also called a hog ring. \u00a0Milwaukee does sell both tools with either configuration. \u00a0So what is the difference? \u00a0The friction is great for one handed socket changes. \u00a0The ring holds the socket on the anvil by applying outward pressure. \u00a0They are easier to get on and off. \u00a0The detent pin does take two hands to get a socket on and off. \u00a0You need to push the pin down and slide the correct style of socket on the wrench. \u00a0When you need to take off the socket, you have to push the pin back in to slide the socket off. \u00a0As you can see this style does take two hands. \u00a0There are many advantages of a detent pin, but one advantage is the socket stays in place and will not come off until the user wants it off.<\/li>\n
    2. Weight<\/strong><\/span> – As you would expect the weight would be different with the high torque wrench and the compact wrench. \u00a0The high torque weighs about 6.7 lbs while the compact weighs only 4.1 lbs. \u00a0Not a huge difference, but try using it all day long and you will see the difference.<\/li>\n
    3. Size<\/strong><\/span> – Again one says compact, so you know one is shorter, but how much? \u00a0The high torque wrench measures 8-7\/8″ while the compact measures only 5-3\/4″ \u00a0 Might not sound like a huge difference, but it can mean the difference between getting a tool in a tight spot and getting the job done and not getting the job done.<\/li>\n
    4. Speed<\/strong><\/span> – While the high torque is heavier and bigger, so you would think the high torque would be faster, right? \u00a0The high torque has an RPM of \u00a00-1,900, while the compact version is 0-2,200.<\/li>\n
    5. Impacts<\/strong><\/span> – The compact is a little faster, but what about the IPM? \u00a0The high torque has an IPM of 0-2,200, while the compact has an IPM of 0-3,200. \u00a0So far it seems like the compact is the way to go? \u00a0Well before we jump into that, let’s look at the torque. \u00a0Considering one is called the high torque, my guess is that one would be much better for torque.<\/li>\n
    6. Torque<\/strong><\/span> – Okay, the high torque has to have more torque than the compact, right? \u00a0The high torque puts out a whooping 450 ft-lbs of torque, while the compact puts out 2,200 in-lbs of torque. \u00a0How could the compact put out so much torque? \u00a0Oh wait it is in-lbs of torque. Let’s see what that would be in ft-lbs of torque. \u00a0It would be equivalent to 184 ft-lbs of torque. \u00a0That is a huge difference. \u00a0The high torque impact puts out over 100% increase of torque over the compact.<\/li>\n<\/ol>\n

      One other note. \u00a0The compact has an LED while the full size does not.<\/p>\n

      So which one do you go with?<\/strong><\/span><\/p>\n

      All right so which on do you go with? \u00a0Well that really depends upon what you are doing. \u00a0Both are quality tools with a proven track record. \u00a0Both have a great motor design. \u00a0So the question really comes down to size and torque need. \u00a0Once you figure this out, just pick the anvil style you want and you’re set.<\/p>\n

      If you are a small engine guy or mechanic doing some tire rotations, the compact is the best option. \u00a0With 184 ft-lbs of torque, you can break loose any nut or bolt on a car especially considering most lug nuts are below 100 ft-lbs of torque. \u00a0If you’re a contractor, residential or light commercial, the compact is also a huge advatange for the size and amount of torque.<\/p>\n

      However if you are working with much bigger machines or bolts, you can’t pass up the high torque wrench. \u00a0At 450 ft-lbs of torque, there probably isn’t much of anything you can’t break free or tighten to specs.<\/p>\n

      Again only you really know what applications you will be using these tools for.<\/p>\n","protected":false},"excerpt":{"rendered":"
