If you are surface scrolling, these might work fine for you. If you are slotting, you will NOT achieve the size slot you need with these!
I ordered a Dremel 9901 tungsten carbide cutter (advertised as "Dremel 9901 Tungsten Carbide Cutter by Dremel"). I received two loose bits in an envelope (no Dremel packaging), and one's cutting surface ranged from .095 to .096 inches in diameter while the other ranged from .088 to .091 inches in diameter. I also have no idea what these cutters are made out of since they aren't in manufacturer's packaging.
I contacted the seller and received this response: "It appears that you were shipped the wrong items by mistake. In order to correct this there are two options: would you prefer to receive the correct ones or receive a full refund (including shipping). If you choose to receive a refund, please provide your Pay-pal account and a transfer will be made. You may do as you see fit with the original items you received but do not send them back."
I told the seller that I wanted what I ordered, and he again sent me two loose bits. While the cutting surfaces on these bits are closer in size to the genuine bits, they're still off (one's .124 inches in diameter and the other's .120 inches in diameter). More importantly, no Dremel packaging. Again.
These are not genuine Dremel bits; they are most likely imitation bits purchased in bulk and shipped in pairs so customers think they're getting a deal. The reviews confirm this since real tungsten carbide bits don't perform so poorly or break so easily. Real tungsten carbide is also expensive, so why would you get two when you order one?
