Best type and brand of screw machine drills:

[ome]

I would say 135-degree point angle, split-point, in stub length (aka "screw machine length"). The stub length gives more rigidity (stiffness) to the drill bit, more than the lengthier "jobber's length" drill bits. The split-point helps prevent "walking" when the point first meets the metal's surface. And the 135-degree point angle simply lets the drill diameter become fully involved in the holemaking process a few thousandths sooner. That's just my opinion. lrsglory has an excellent point, about centerdrilling a hole with a center drill prior to drilling your final hole.

Thanks Doug,
took your advice and got decent deal on 115 piece stub cobalt 135-degree split point with case.
