Re: Drill Doctor
M-7 HSS material with 135deg split point work great, are tough and durable. Second choice would be the same made from M-2 HSS. Both work great in hand operated drill motors. M-42 HSS Cobalt bits are not as durable and are better suited for drill press use where feed/speed are easier to control. A good set will cost around $100. My company has them and can help if needed.
The drill doctor can get you out of a bind but a spare 29 pc index cost about the same.
