This is it OP

If you are drilling block, their regular cordless hammer drill is fine. If you are drilling real concrete, you want a dedicated sds drill

Sometimes it’s nice for them to have an easy job and it makes future customers.

If I'm following correctly based on all your comments etc.

"T bolt hose clamps" is what your looking for. 2.5inch is 64mm and a 10 pack on Amazon for 26$

Lmk if you can't find them and I'll get a link.

Probably solid enough for OP's needs. I wouldn't do it on a chair I planned on sitting in, but for this it should work.

Honestly I'd just cut the end of a 2x4 to get a pressure fit from the ring, but anything big enough to hit the 2.5" ID of the ring should have enough surface area that even end grain to end grain you'd still have some decent hold.

Only thing throwing me off is the bolts, as an impact driver is better with those. Also, impact drivers are better with longer (3-5") screws, as they tend to break the driver bit before stripping the screw head. This is a double edged sword, as they can have a bit too much power to be convenient for short screws. Where an impact driver may fail to meet your requirements is that impacts do not have an adjustable chuck to facilitate different sized drill bits. Drills and impacts each have their strengths, and the unfortunate reality is that multiple tools is the best option. However, if you are limited to one tool I'd have to recommend a drill.

Milwaukee makes some of the best cordless tools, but they also make lower grade stuff. Top of the line is brushless, and those cost significantly more. If I could afford it, would switch to all Milwaukee brushless tools.

I hate having multiple brands of cordless tools with their respective incompatable batteries and chargers, but it happens when you're on a budget or in a pinch. In a budget, got a brushed 18v Bostitch impact + drill for maybe $120 several years back and it's performed well. More recently in a pinch and got a brushless 12v Skil set with drill, impact, oscillating cutter, and bluetooth speaker for like $200. It too has preformed well.

For Gd's sake, if you value your fingers or if you don't want to risk the tube kicking and flying around, then go buy a longer tube. Just not worth it.

For a moment, SS meant something so different.

portable bandsaw. you can clamp the tube in place and cut with the band saw. The blade thickness is perfect for this type of work you wish to do.

Tubing Cutter

Run a dowel through the tube leaving enough to hold on to, then use a tubing cutter.

I'm not sure this is well expressed, but try to imagine the steps and how it all fits together.

If gluing doesn't work, try this: smack in the middle of the length of the tube, drill two holes, one on each side of the tube, and run a screw into the wood through each hole. You'll then have a wood piece with SS material over it, with screws going through the SS ring into the wood. The screws keep the ring from rotating.

To cut, clamp the whole thing in a lathe. Turn the lathe and cut the far end of the ring so it has a perfect edge. Then move that tool/blade closer to the mounting screws and cut through the SS. That will give you your first ring. Move the blade one step closer to the mounting screws and make another cut: this will give you your second ring. Continue until you've run out of material.

Try asking your local metal supply amd fab shop. You will get the best results this way

I would get a longer pipe and cut my small rounds from that

>Seems like there should be some biscuit or cookie cutters out there that will work.

They come in sets, so it's an expensive way to go. I'd need a couple of dozen. Biscuit cutters are also probably too deep, being 3/4+. I don't know yet how important the height is; there needs to be some airflow over the baking item so it will dry and brown.

>A pipe cutter can do it but they're expensive.

Yeah, the cheap ones can't handle the diameter and the ones that can seem to get pretty pricey.

My wife disagrees.

thanks, any specific model?

>- drill holes on concrete/brick walls

Any hammer drill will work but an SDS drill is best if you're making a lot of holes. The neatest holes are made with Forstner bits. Pretty good holes can be made with hole saws or spade bits.

Whatever their drill is will do all of those things. You’ll need a masonry/concrete bit for the holes, you’ll need bits and sockets for screws/bolts and either a spade bit or hole saw for the circles; depending on their diameter.

All of these things are common accessories for drills and are made by hundreds of different companies. You can pick them up at any mom and pop hardware store or big box store.

If I were doing this in my basement, with the tools on hand, I would do the following.

Insert a long bolt through the tube, add a washer and nut, then tighten firmly.

Clamp the exposed end of the bolt into the soft jaws on the vice.

Use my tubing cutter to portion off the pieces I need.

Disassemble and de-burr.

Failing that, de-burr and lube the tube, then jamb a wooden dowel through it, and take that to the cutoff saw.

A pipe cutter can do it but they're expensive.

Seems like there should be some biscuit or cookie cutters out there that will work.

Seamless tubing is hard to make, the price reflects the labor more than the material. Stainless strip with a spot weld to make a ring is a cheap process.
