Q: New to the dremel scene. how come every time i buy dremel bits they don't fit my dremel head they fall out!! what part am i missing??? help please!

You need to buy a different Collet . Take your Dremmel tool and the bit you want to use to Lows. The salesman will help you buy the collet that you need

Q: I am looking for diamond bits to drill holes in 6mm glass for jewelry. Would these work?

tThey are awesome, one trick to keep them from over heating and dulling, find u a stainless steel pan cover what u r drilling with water, then drill. the drill bits will last a long time, i have used them on steel when i make weapons to,water keeps them cooled down. they are a great set of bits.

Q: Do these work with a dremel tool? Some of them look very small.

The two larger bits do fit my old Dremel with a smaller chuck. The 1.5 mm fits the chuck on my drill press. Alas, the 1 mm needs a small chuck and the two I have bought from Amazon are tedious to align and do not work very well. Frankly, you would probably promptly break both the 1.5 and 1 mm in a Dremel because they are so delicate and need precise alignment for drilling. I have used all the bits with a drill press (with PLENTY of water and SLOOOW pressure) and they work great. One broke simply because I moved the vise and snapped it off. I broke a 2 mm, but simply used the broken bit for another bunch of holes. Broke again and I am now using a stub and it works just fine. Obviously, not deep holes! Drilling on polished rocks of different varieties. Work great.

Q: Need to drill 30 screw holes in plexiglass and Lexan panels, will the bit last through 30 holes and do I need to cool bit while using?

You're better off with regular drill bits you wouldn't want to use this type of drill bit with diamond bits it will cause additional heat and melt the plastic vs. drill through cleanly. These are a very abrasive way of drilling and only used for masonry or actual glass.

Drills through my sea glass

I bought these for drilling sea glass and pottery. They are really good and I’ve found them to last a lot longer than I expected for the money. Very happy and will buy again once these have worn down 👍🏼

Drills sea glass well

Bought these to drill sea glass (for making jewellery). Work well, drilled about 9 pieces with 1mm before blunting. Need to keep it well lubricated. Fitted on Aldi own dremel type tool no issue.

They are ok, not the best

I got these to drill through some small flat stones that my wife was making jewellery out of. It was hard work and took some time just to drill one. I went through a few of these just drilling a few stones. I may try another brand to see if there is a difference.

Avoid!

Utterly useless, brittle and a waste of time and money.

Glass drills.

Drills used for drilling glass. The 1mm don't work as well as the larger sizes. Pleased overall though.
