If you’ve been thinking about picking up a high-end die grinder, MAC’s offering a pretty nice deal right now: they’ll give you a free standard-duty 1/4″ mini die grinder with the purchase of a heavy-duty angle head mini die grinder for $75.  If you’re actually in need of both tools, that puts ’em almost down into the Harbor Freight price range.

We came across this in MAC’s February newsletter, so the deal should be good through this month — or until they run out of their “limited quantities.”

    While the timing is off on this one for me, I have to agree that it is a good deal.

    I think this is a good time to point out the post regarding cheap air compressors–something that I am currently in the market for. Unfortunately there wasn’t much in the way of comments on this entry, but maybe it could be revisited:

    Hey nrChris I visited, and put a belated comment into that entry you posted there.

    These Mac airtools look suspiciously to me like the HF die grinders I have, with MAC cast in to their sides. I wouldn’t expect CP performance out of these myself.

    I have a genuine CP die grinder, paid like $109 for it if I can recall correctly. It is rated at 1/2 HP. I have some of the $9 HF die grinders too, the power difference is substantial. Air die grinders have a number of things going for them over their electric counterparts. But they also have a few things going against them too.

    On the plus side air die grinders are smooth, quiet, and fast. Also, being air powered one does not need to worry about having any electrically shocking experiences with them either. Furthermore the user friendly stalling of air motors can be a plus over much more torquey universal electric motors. Another plus is the compact size of air die grinders over comparable electric models.

    On the down side with long runs these tools can be CFM pigs, requiring a substantial air compressor for long runs. In the cold they can freeze up, or at the very least be extremely uncomfortable to operate. Then there’s always the, I have to bang up a tank of air to run my tool syndrome to contend with too. If instant gratification is your ultimate goal there is an awful lot to be said for the plug it in and go convenience of electric die grinders.

    It depends on my situation which I reach for today. But for a lot of jobs an electric die grinder is the way I go.

    Hot tip, air die grinders are one of the many air tools that benefit from having an air swivel attached to them, for greater maneuverability. Beyond that, as handy as the angled die grinder looks, it really isn’t, and is harder than an inline to control. Don’t just get the angled one, and figure you have all the bases covered. Straight, inline die grinders are the more useful tool design.

    Not only are there power differences between HF and a good die grinder as Paul states above, there are also vibration and noise differences. I’ve used Dotco, one of the best out there, and I’ve used HF air grinders, and the Dotco units were quieter and smoother in addition to being more powerful. Like most things Harbor Freight, their grinders are great for occasional use. If you’re going to be using the thing for extended periods, you’ve got to pay for quality. I’d be surprised if the MAC units are the same as the HF ones, though.

    These eventually got recalled due to safety hazards.

    I have to wonder how you heard about this? I knew there was some news report about a couple coming apart in mechanics hands with dredful results but was told they were isloated incidents. Please do tell…

  6. Mac Guy says:

    Recall??????? That is funny I sold the hell out of these things and have had only a few problems. They are a cheaper die grinder set and are marketed that way. BTW THERE IS NO RECALL.

  7. Jarod says:


    One of my techs had one come apart. Huge lawsuit in progress becasue Mac refuses to initiate a recall. And we’re located in the hometown of Mac tools – Westerville, OH!

  8. Jerry says:

    I had to take of of my tech for stitches after one came apart in his hand. mac is trying to say he wasn’t using it right…

  9. Drewski says:

    Yep, I’ve seen them come apart. I have only been turning wrenches for 2 years and am just not im pressed with mac’s quality. Our greaseball mac man comes around selling this junk then can’t even getsimple things for waranty like sockets and ratchets. Mac tools = crappy tools, crappy dealers, and crappier service!!! If you want real tools you gotta buy snap-on. Hell, even cornwell is better than mac!!

    Had a tech transfer in last month with one of these…broken with little use. Looks almost new out of the package and no place to get it fixed. Have not had a mac man in years…didn’t think they were still in business anymore since stanley took them over and snuffed them out.

  11. Rodge says:

    My dad grew up with Mac Tools. Back then, they meant someting. Now they’re no better than Harbour Freight in an ulgy yellow truck filled with made in china crap. That is if you can find them. They’re a dying breed. Our last mac guy only lasted a few months.

  12. Tyler says:

    Just bought this on the truck today…too good to pass up
