The original Truebite Cutting bit was introduced to the ceramics hobby industry in 1983. Certainly, these specialty carbide-cutting bits are as valid today as they were then.
Truebite carbide cutting bits come in 1/4″, 1/8″, 1/16″, and 1/32″ sizes. Also, they all have a 1/8″ shank. These were originally designed with the purpose of de-grouting bathroom tile in mind. Thus, they can drill and router tiles very well. In addition to tile work, they are very useful in hard-to-reach areas.
Any drehmel tool will work with these. That is to say, it doesn’t matter if it is a constant or variable speed. The reason is that these bits work through speed and light touch.
All the Truebite cutting bits have a fishtail point and a router surface. Firstly, the 1/8″ is perfect for slotting and general-purpose work. Next, the 1/32″ is good for ceramic Christmas tree holes. Lastly, the 1/16″ is great for salt and pepper shakers.
The fishtail points easily cut through the glaze. Furthermore, the side of the bit can be used to enlarge holes without chipping.
