What tool should I get to make the countersinks for the AN246AD-3-4 solid rivets that are used to attach the wingtip attachment plates? These have a 100 degree angle for the countersink.
For what it is worth.....single flute countersinks, in my experience, make a much neater cut without chattering or tool marks. I did get three different sizes, however, I don't think a person would need more than one size as larger diameter countersinks can be used on any smaller diameter work.
For bonus points...the single flute countersink makes a great deburring tool.
This might sound strange at first read, but I much prefer the Zero Flute Countersink. I happened on one many years ago at an aircraft fastener business owned by a friend. I then searched for a replacement not knowing what they were called. Amazon has them.
For what it's worth, For the use you are contemplating. Harbor freight has a multi size pack for just a few bucks. I used them for a bunch of different things & they worked great.
