and Cincinnati Bob…(sorry)
Got a heavy duty Milwaukee hammer drill for masonry. It uses big bits with big splines to lock them in. Need to drill a 2″ dia. hole in a 10″ log. ‘Fraid I’ll burn up my 1/2″ drill. But if I had an adapter for the Milwaukee so I could use a regular chuck… Looked – can’t find. Any such critter? Thanks.

Yeah, I think that's what I'm looking for. You're a better searcher than I.
make sure of the type of splining you have....

Spline drive is different than the SDS/ 3 Jawed chuck Imerc posted. I will echo His suggestion of double checking the drive.
Also will echo his question of what brand 1/2 drill? Most 1/2" drills will handle a 2" bit , chances of breaking your wrists using a 2" bit in logs are probably better than chances of burning the drill up.

wundered if he was referring to an SDS as a spline...

I was a bit confused in my post this morning. First you are both correct it's sds not spline. The drill I'm afraid to burn up is actually a Milwaukee 3/8". The Heavey duty hammer drill is a 1 1/2" milwaukee rotary; 5315 - 21. Looks like the sds adapter 48 - 66 - 1370 with 4 flutes is right. Though it was up earlier, that part of the Milwaukee site seems down right now. Can't find a direct reference that says this adapter fits this drill. Tried checking with local suppliers; they just sell the tools, can order parts, but don't know any more. Thanks. Much farther along. What does SDS stand for?
save the hassels and get a 1/2" milwaukee magnum...
that adaptor will cost you almost as much or more as a new drill...

Any SDS/Spline adapter should work, doesn't have to me Milwaukee. I just bought a Bosch for $40 at Home Depot. There are a number of online places that sell them, and there are a number of manufacturers. SDS? I don't know, hazard a guess at spline/detent/spline

another deal that doesn't happen around here,,,
80$ for an adaptor...

one tip for drilling in logs only use sharp bits. i've seen guys smoke new drills by being to lazy to change out a dull bit. definetly need a heavy duty 1/2".
What rpm does your hammer drill turn at? Does it have a built in clutch if the hole requires too much torque?
My old sds hammer drill (It is badged hilti but looks like a bosch) turns way too fast for a 2" hole and as I recall it stops if it meets too much resistance.
I wold look for a low rpm drill in the 500 rpm range. Anything over 850 rpm I think you will hurt yourself with a binding bit or burn up the drill.
If I only had a 3/8" drill and I had to drill a 2" hole I would use a holesaw, drill as deep as I could. Use a chisel to break out the wood plug and continue drilling as necessary to achieve the desired depth.
There is a trick where you drill a 1/2" hole on the perimeter of the wood where the holesaw's kerf will go. It allows the sawdust to accumulate in the 1/2" hole rather than binding up the holesaw which can tremendously increase the load on the motor.
I'd recommend a Forstner bit, or the similar saw tooth edged bit, and an extension. Since the depth of cut is limited they don't dig in bad, and exert a lot of torque so you can't damage the drill or your wrist. Be sure to pull back out every inch or so, because there are no flutes to carry the waste back out. If the wood is really green, you might want to squirt the bit down with pam or a similar cooking spray every time you pull it back out.
You should not use a hammer drill or a roto-hammer, in any but drill-only mode to drill wood. A forsner or similar drill should drill your log with a standard 1/2" drill motor supplying the umph
Rotary hammers ARE heavy duty motors, but not for drilling large diameter holes. You probably burn up your rotary hammer trying it.Spend a $100 and get the 1/2" 550rpm model - you can't kill it and it'll be handy to have around.JT
