drill bit question

HI all

My FD Puzzle blades say I need to use a #71 wire bit. I did that, in my dremel plunge router and the blade will not go through the hole. Somebody is wrong. Why do they say to use a number 71 when it won't work? that is what it says on the FD chart for that blade I dropped to a 68 and it went thru fine.

Interesting fact I thought I would point out.

A quick check online shows that a #71 drill bit is .026" dia. A #2 FD puzzle blade is .015, while a #3 is .031 so iin that case would not fit in the hole.

 

Another thing is check the drill bit. I have found that in some of the less expensive drill sets the marked dia is more of a suggestion than the actual dimension of the drill.

I check all my drill bits with a Electronic Caliper I got from Harbor Freight for $10 and they are off by .0005. When using ply wood I have to drill the 2nd time from the back so the Blade won't hang up. It's matching the Blade with the Drill bit.
