7Pcs T Shape Diamond Cutting Burr

These, used properly (esp. with proper cutting oil when cutting metal), are really great! I wish the seller would make available packs of, say, 5 or 6, in each size. Maybe 10x for real power users - hahaha. I use the 14mm size 10x any other size. Edit/update: The Seller responded to the question I sent them (thanks for the quick reply!), but, they may have not fully understood my question. The idea would be that in the future(?) they sell THRU AMAZON, as they do at present, but, they would add listings for, for example, packs of 6 ea. 14mm, packs of 6 ea. 10mm, etc. (One seller already offers 10-packs, but only up to 8 mm, at a high price.) I believe something like "6-packs" would appeal to very serious hobbyists, custom shops, and small manufacturers like me. Before my 14mm cutting burr entered the orbit of Neptune and was lost (slight joke and long story) it withstood some pretty hard use: These are a really good product, used correctly (which includes cutting fluid or water if used to cut metal.)

Worked perfectly to cut a glass scale for a DRO that was installed on my Bridgeport milling machine.

Excellent tool for cutting Granite.

I got these to clean up/cut slots in large screws with buggered slots. They worked OK for this, and I am sure they would be useful for precision grinding/cutting/slotting. The price was right, and they run true and smooth with no vibration. Took a star off because they seemed to show more wear than I expected for the little use I gave them. Hopefully, it is just cosmetic and the diamond dust will prove to be more durable than my first impressions.

Cuts high carbon steel like butter! A+++

Added to bits for dermal

Nice all the way!

These are the perfect cutting wheel for my carving smaller pieces of jade and marble! They work great and the Diamond edge holds up nicely and lasts a long time

These cutting burrs work very well. Good quality. It does the job. I would recommend buying this.

all good
