“The PCD Countersink Bit that Qual Diamond made for us works great! I’m more than happy to say I’m pleased with the outcome of this tool. On top of that, Qual Diamond was on top of the process every step of the way and was easy to work with. The bits we were using would only last for about 30-50 holes drilling fiberglass and carbide countersinks, Lasting for about 100 holes with the PCD Countersink that Qual Diamond made for us, We are currently able to produce 700 holes and still going. It’s really impressive how long it has lasted and doesn’t seem to be dulling out. We will definitely order similar tools in the future!”
