Roll Form Tap Drill Chart

[projectnut]

Does anyone have a source for a wall chart for Roll Form Tap drill sizes? I'm starting to use them more often for blind holes, and am getting tired of having to look up the drill sizes. I've found several printable charts, but what I'd ideally like to find is a wall chart similar to those used for thread cutting taps.

Hey Nut . Not sure if you can download this or not . If not , try getting ahold of Guhring and see if they are available .

I just looked at the Guhring link out of curiosity and they are having a great overstocked sale on spiral flute bottom taps thru the end of next month.
No wall chart like your looking for though.

I don't own any form taps but for my traditional taps, I keep them in the little cases they come in. Although I have multiple tap charts handy I even get tired of looking at those. I've started writing the drill size on the cases. To make things even easier I have been meaning to buy dedicated drills to keep with each tap but I just never start doing it when I remember. Maybe I'll just get em for the taps I use the most often.

What is the 2BX fit for the taps mean?

If you find a downloadable chart you like online, you can print it at Staples at any of the common paper sizes, and they also print on heavy weight paper.
