Most rivets use a wire size drill depending on the rivet size. Common rivet drill sizes #10, #11, #20 or #30. Shouldn't need a punch with the right size drill.
That's for CNC applications where they basically making a dimple. This guy is trying to drill holes with a hand drill or press. A center punch works fine for 118 deg and no need for one if you have a 135 deg split point. Never any need for a pilot drills that go's all the way through the piece...
See picture. Just trying to help a noob not make the same mistakes as you. google center drill. Every link you go to off that calls this a drill & countersink combo

Any drill bit manufacture will tell you exactly what I'm saying. You're just wasting money on a pilot drill. And the "pilot hole" drill everyone keeps posting pics of isn't a "pilot drill" its a countersink.

Drilling holes is part of my steady paycheck! You must not be using good bits!

You aren't suppose to drill a pilot hole. That actually wears the drill out unevenly stresses out the cutting edge. Drill bits are used to drill holes not expand existing holes.
When in doubt use a Norseman 190-AG. Cobalt only works better in free machining stainless. Hi-Moly bits are better in work hardening stainless. Dewalt, and Irwin bits are ****!
Stanley will screw this up like they have previous brands. Stanley should stick to Tape Measures. Dewalt is no longer "trade" trusted. Just bought Irwin and Lennox from Newell and have already screwed that up. Does anyone remember what they did to the Goldblatt and American Brush brands? As a...
Might make some enemies here...
Hate the thought process of the Sears / Cman generation regarding warranty. This is the reason companies have been going off shore for years. Main brands are making stuff cheaper and charging you more so they can cover the cost of your returns. Specifically when...
