Jan: You stated that it is possible to salvage broken carbide drills by grinding an "engraver's tip" on the broken end and that this new tool could be used for PCB machining. If possible, can you provide details that will describe this procedure? I have been using these HF carbide drills for 3-4 years with no problems in a T-Tech machine. I have a 9x20 metal lathe and a small diamond wheel. Al Daniel [Non-text portions of this message have been removed]
