Can anyone recommend me a good 1/4 inch die grinder burr that is capable of cutting porcelain tile? Carbide is not cutting it.

Question- where to get quality diamond bits
There are three primary types of diamond bits that I have worked with, electroplated, vacuum brazed, and sintered. Electroplated : cheapest and often very short lived, typically 100 grit and up. Even if you always use them wet they rarely last long unless you are making tiny things from very soft stone. Not worth buying for stone carving in my opinion. Vacuum brazed: more durable surface application of diamonds. These are usually coarser diamond and can often be bought on burr sets for carving. The quality varies greatly, but they are useful for soft stones like limestone or marble as long as you do not overheat them. Sintered: diamonds suspended in a metal(often bronze) matrix. Very durable, often available in specific grits. These will carve stone as hard as granite but usually cost a fair bit. While you can overheat these, it takes more punishment and can be used dry if you know what you are doing. Extra: I often use double-cut carbide burrs on stones like marble or softer that I buy from my local independent tool store. They last well and are reasonably priced and readily available. Some of this stuff is available from Neolithic stone tools, or other carving supply places. I am in Canada so my suppliers will be different and McMaster Carr is a pain to get here so I don't know what they have. Use some Google-foo and I am sure you can find sources now that you know the types. More on reddit.com

Can I grind plastic with a diamond grinder bit?
Could do some damage or melt instead of grind because of the fast spinning. Would recommend sanding by hand for plastic More on reddit.com

Carbide Burr Bits for Die-Grinders - Amana Tool Solid Cut
It does this by incorporating a positive cutting rake angle that gives great “bite” into the material and yet,­­­ is not so aggressive that the operator fatigues quickly after using it in a hand piece. The steel shanks are ground, which sets them apart from our competitors. The solder joints are clean, with no excess solder gaping out from the sides between the carbide bud and the shank. Applications: To be used with air or electrically driven hand die-grinder with a typical collet mechanism or knee mill with an air-driven spindle speeder such as an Air Turbine product.

r/stonecarving on Reddit: Question- where to get quality diamond bits
April 27, 2021 -

I’m newer to this and wondering where does everyone get their diamond bits either for Dremel or Micromotors from? And what brands?

I’ve noticed even the Dremel branded ones seem to wear out quickly and are just coated with diamond dust rather than having diamond dust throughout the bit so it continues working as it wears out.

Is there a specific term for that type of diamond bit? Searching only brings up the cheap coated kind.

You can get good quality sintered bits from https://jadecarver.com/ . They are based in the US but ship internationally.
