Drill America jobber length drill bit. Manufactured to National Aerospace standard 907. Made of heat resistant cobalt, they display higher red hardness which permits speeds upto 30 percent greater than High-Speed Steel drills and are especially effective in drilling tough, high tensile strength materials like PH stainless steel, inconel, and titanium.
Cut through an FSB and barrel like butter. I think it helps to put a drop of oil down in the hole after getting it started. It held it's edge well enough to drill both holes with a single bit so they're plenty sturdy.
