Why do you feel you need a Cobalt drill? I have held a Journeyman's card as a metal model maker for 12 years, drilling through some pretty tough stuff and have never needed a cobalt drill bit. Unless you are working with ceramic, all you need is too keep the bit sharp and know how to use it. Believe it or not, most people do not know how to use drill bits properly and apply WAY too much pressure to them.
Do understand I only ask, as a lot of people are suckered into paying 3X more for some thing they are told they need, yet really don't need it.
Here is who I deal with. Production Tool & Supply
