Question

SDS Max Or Spline Rotary Hammers


I'm pondering getting a medium duty rotary hammer and was wondering what everyone prefers, SDS Max or Spline? Does one work better in some applications than others or why is there 2 choices? Thanks

The SDS max is my goto. Unless you're drilling or chipping big stuff the spline is too big imo. I believe spline only comes in the big stuff.

Re: SDS Max Or Spline Rotary Hammers


spline comes in everything sds max does . I have both sds max and spline . I Sujest the that you hit your supply house and see what they carry in bits .what is easiest for you to purchase . I suspect it is SDS MAX . The real money has been in the bits for me .some of the longer larger bits are over 100$ .not sure what you will use it for or what varity of sizes you will purchase .I now have a ton .every size requires several lengths . what size holes are you expecting to drill . SDS plus can handle just about everything size wise just fine in a smaller easier to use machine

Check ebay and craiglist . used ones can be a lot cheaper .
mine are primarily used in seismic upgrade work.

You can use SDS Max with the spline but the drill itself is a little big for anything SDS Max is needed for. Imo

SDS max and spline are the drive type . they are not compatible .i believe spline was here first and sds max [sds ] came over from europe .I believe in our time , pretty sure when the two of us got into the trades sds wasn't very popular if around at all.there were a couple of chuck/shank types .spline being one of them .the bits or cutting edge,cutting type has come along way in the last 10 years let alone 40 yrs .

I understand the difference. But you can use an sds adapter on a spline, but not vis versa I don't think.

Re: SDS Max Or Spline Rotary Hammers


I was doing other online research and they say the same, that SDS Max is the way to go.

I currently have a Bosch Bulldog that works great but I'm in need of a 12" deep 1 1/2" hole through a footer and it doesn't look like that's possible with the bulldog. It would also be nice to have something a little bigger for misc. chipping. Any recommendations on brand? Are the Makitas any good? Looks like they have a few options made in Japan. My boss has a 20+ year old Bosch that I've used in the past that I've never been a big fan of but a lot has changed in 20+ years. I know Hilti used to be considered the gold standard, is that still true? It's amazing how many choices there are...

I just purchased a Bosch 1-5/8. Great great for digging as well.

Is that one of their German made models? It looks like it gets excellent reviews.

My Bosch is similar (older version), great tool. I use it more for digging and chipping than drilling. Extensions save my back ....... https://www.homedepot.ca/product/mak...ter/1000777226

Re: SDS Max Or Spline Rotary Hammers


another insight to add to your choice .from what i have read so far not sure what your needs are . one thing that is important to me is to be able to put hold down bolts for shear walls in straight .some machines are to wide to get close enough to the post to drill a straight /plumb hole .tweaks me to do them at an angle .

One of the 1 9/16 machines has a switch on oneside that gets in the way .the other 1 9/16" machine is just to friggen large ,wide .oh well .

Re: SDS Max Or Spline Rotary Hammers


I have this one form Milwaukee.

https://www.cpomilwaukee.com/milwauk...up=miln5316-21


1 3/4" SDS Max.

It's a beast.

Made in Czech Republic. Seems pretty solid, I've had it for a couple years.

Re: SDS Max Or Spline Rotary Hammers


Since everyone seems to give the Bosch good reviews, I ordered one last night. Should have it Friday.

I can drill 3/4" x 6" or 3/4" x 7" holes in aged concrete in less than 30 seconds a piece.

Makes quick work of 4" holes, too. I'll drill a bunch of smaller holes and then blow it out with the chipping function.


The chipping function is really good. I've chipped out sections of footings and sidewalks with it.

It's big and heavy, but for the remodel stuff that I do, it works well for me.
