Skil model 732 RotoHammer

I always take YouTube comments with a grain of salt. Sometimes they are very useful, and sometimes people have some vague relation to the topic and feel the need to say something even if its wrong. They can sometimes be a different point to start looking for information in either case.

Found some bits here:

=== Carbide Tipped Heavy Duty 9/16" Hex Shank Masonry Hammer Drills, commonly classified as the Skil 728 Hex Shank, are designed to fit the following 9/16" hex drive rotary hammers: Skil 628,728, 731, 731,

From this page:

I did find those guys in my initial search. As it happens the machine came with a few bits, not in great shape but usable. I bought it for $50 somewhat on a whim, intending to drill some anchor holes in concrete. It's very much a handful to control and heavy to boot, so it's not seen much use. Looks like its previous life was hard, however.

That's considerable help as it is. I'll not try using oil! One mystery remaining is an adjustment below the motor on the gearcase may "T" and "L" with opposing direction arrows. There's a matching Torx-like key among the items in the kit. Perhaps something to do with the "clutch"? Not clear on what the clutch is for, unless it's to prevent wrapping the operator up if the bit jams....

Thanks _very_ much for writing!

I would guess it is for the Clutch too. Read mention of the Clutch and a key supplied in the original kit for adjusting it on the catalog page...

Many, many years ago I ran a Rockwell a few times that looked a lot like that Skil. Was drilling 2-3 inch holes through a poured concrete wall with a core bit. Once the bit was deep in the hole it was quite easy to tilt the machine slightly and cause the bit to bind up. The clutch would allow it to slip, stop turning while you adjusted the angle back to where it wouldn't slip and keep drilling. Can only imagine how nasty that could be without a clutch allowing some slippage😬️

And you're most welcome👍️
