Old tool ID - Cleaning Dad's tools

[broncoman1972]

I'm cleaning some of my Dads tools that are rusted from being drowned during last year's flooding in our area and I found a few that I'm not sure what they are. The 1st one I thought was hole saw chuck but there is a c-clip preventing the nut from coming off or moving far enough to disengage the pins. There are no markings or stamps on it that I've
found. The second I've seen some from my Grandpa's tools, but have no idea what they are.

So, what have I got here fellas?

The first item is a mandrel for a hole saw... It's a nice mandrel by the way.

The hole saws ... thread onto the "bottom" per your picture... there will be two pins that would lower into the holes on the saw and then the nut will tighten down holding the hole saw on and preventing it from spinning...

You got me on the second item...

Second one perhaps a star drill?

Second item is a star chisel. I believe they were used in masonry work.

Milwaukee uses that hole saw arbor design.

Yup. That's how you drill holes in concrete or rocks the old (hard) way. You set the star drill on the point where you want the hole and repeatedly whack it with a (roughly) two pound hammer (some refer to it as a drilling hammer or a "lump" hammer) while turning the drill (chisel) a quarter turn between each hammer strike. Stop frequently to blow the dust out of the hole and if you're diligent you'll have a hole in the rock wall by sundown. Whoopee! Only one or two more holes to drill and you can hang that gate!

Don't chuck out those old drilling chisels / star drills though - the steel was often of very high quality and they're superb for forging into other tools, or making knives!

As long as you're careful about generating too much heat when grinding or cutting, you can make yourself some nice specialty chisels or punches.

All the big boys use that design.

I have run up against walls with a lot of rock in them. Sometimes my old pistol grip, corded, 1/2" Milwaukee hammer drill just could not get past one. A slam with the star chisel and I was back in business. I know there are bigger,and better hammer drills but that was quite a while ago and I rarely drill concrete any more.

Many years ago my dad had me and my younger brother help him drill some holes in concrete. We were probably in our early teens. The drill was likely one of his father's tools and may still be around someplace. With three men working on it it's surprising how fast a star drill can work. One guy to hold the drill (with pliers as a standoff) and the other two taking turns to whack the drill. Once a cadence of hammer-hammer-turn is established it goes pretty well.

See lots of the, the bottom one stumped ,e for the longest time then I seen a new in pack one star drill lol. GL with your dad's tools mine gave me alot of his as he's getting older most were snappy. Still don't know what you use a star drill bit for masonary?

Ever heard of driving steel? (John Henry ... Was a steel driving man) those star bits (usually much larger) is what was used to drill into rock to place dynamite when they were blowing through the mountains making the railroads or even mount Rushmore for that matter.

Very cool info guys. I guess I was right on the arbor, but was picturing the hole saw mount sandwiched in the middle. That threw me off the trail.

Good to know about the star drills too. I figured they were some sort of punch but had never seen ones like these. It's funny, my dad's favorite hammer was always his "lump" hammer, but until today I've never heard another person refer to them as that.

Thanks!

And on a much smaller scale, that's what we used when I was a kid to drill holes in a concrete porch. It made little holes where we would mount anchor bolts for wrought iron railing on the porch.
