Wisfor30 Pieces Diamond Grinding Head, 2.35mm Shank Burr Rotary Set 10 Shapes, Fits Dremel Rotary Tools for Carving Metal, Glass, Ceramics, Jewellery, Stone

Baught these for my husband . He said their quite good . But one broke very easily

They look like they will do the job, but when they arrived a lot were loose and rattling about, though they were all there.

I tried using one of the pointy ones to engrave on a hard paving slab with a 3018 cnc. They fit in a 2.5mm collet.The tip of the bit basically ended up as a naked ball of bare metal. The paver got a 3mm ish trench about 0.2mm deep. So not hugely successful. To be fair, this is not the correct way to use them.I also tried a pointy one on glass. It cut it fairly capably to a depth a bit shy of 1mm but the cut was a bit rough. Bit still ok when I'd finished.

Great set for wood carving. Not sure how long the “diamond tips” will last but its only for limewood so shouldn’t be a problem. There’s loads of options for different angles nooks and crannies. I’m pleased with purchase and at the price I payed its a no brainier!

I should know better. You pay for what you get. Im not an advanced or experienced engraver, but i can do a half decent job, on glass if im asked to. I have a small pen shape engraver, which works a treat. I had just finished engraving wine glasses for a wedding, and i noticed my engraver bit was dull. I ordered this set, thinking i had the deal of the decade. Ha....ha.....They wouldn't even touch the glass. I think they would have a hard time engraving ice cream. tried them in my powered engraver, and the lines if any are awful.

Cheap yet not hard wearing

They do the job!

These look fine and fit for purpose only problem they don't fit in my Dremmel the shafts are to thin
