#1 Asked this question years ago,and.......seemed nobody was impressed with what was out there.Has anything changed in the last few years? Any recomendations #3 I like the Starrett one, with the bonus that they send you one for free (or used to at least). Doesn't have tap sizes for different thread % though, or form taps, if that's important. This'll probably get me flamed, but I really like the one from Littlemachineshop. They have SAE and metric with drill sizes for 65% (I think?) and 50%, plus tight and loose clearance holes. I printed out both, stuck them back to back and laminated it. Use it all the time. Even wrote the form tap drill sizes on it with a sharpie #4 I got some from MSC about a year ago I like, has metric and Imperial roll raps and that was important to me. sent me one with Accupro all over it a few months back. Has cut tap drill sizes and roll tap drill sizes. All decimal equivalents chart too. #5 Many of the big name suppliers will give you one. I have one from Accurpro that's great. GTD and MSC have decent ones as well. #6 I have a little National Twist Drill pocket card I like so much that I scanned it and blew it up to a wall size chart. Just print at 11x17 or so. For thread info I print out my own spreadsheet with much more data than the usual chart. Stuff like plunge depths. That's mostly for lathe work, though it covers everything else too. #7 I have a big Starrett chart but it doesn't contain some things like metric conversions. I wish I had their chart in a modifiable format so I could add to it. #8 I got a nice Precision Twist Drill one taped to the side of the shop fridge. I have no idea where I got it, I think it has to be about 30 years old. #9 Sounds like a great opportunity for a PM product here. Maybe with some choice comments in the margins from

Some of our more "colorful" members.I have a big Starrett hanging on the wall, and their smaller cards scattered around the shop. #10 I have a card from MariTool (well, three actually) that has decimal equivalents on one side, metric and inch. The other side has cut and form tap drill sizes for both inch and metric.along with a 6" scale along one edge. Sorry, no metric equivalent scale. #11 I have a homemade chart 2 to 40 TPI for straight in and at 30* feed with the nose flat and double depth, but lacking major and minor dia. It is handy for a utility thread but I still need to go to the book for a specification class thread.Some free charts to copy /print on the netIt is like this but it doesn't copy well to PM with not having the chart lines..TPI- Straight in - double - At 30 - flat- Threads per inch 2 0.3247 0.64950 0.3749 0.0625 2 2 1/4 0.2887 0.5773 0.3334 0.0556 2 1/4 40 0.0162 0.03247 0.0187 0.0031 40I know, likely I did not need to put in odd threads like 2 1/4 TPI. #12 Free. I like charts I get for free. Starret used to send them out but I went to their site last week and could not find them. #13 I have a Hertel one I got from a friend that works in a bigger shop. It has form tap sizes on it but I have had to cross out a number of form tap and pipe tap drill sizes and write in smaller ones. Apparently they went with the largest tap drill that would give a theoretically correct thread without accounting for drills cutting oversized. #14 I agree Mari tool pocket chart is nice except the green is hard to read #15 Drill/Tap chart This is a chart I made, have as a pdf but had to upload as jpeg due to size. EDIT looks like the jpeg is not too useful, would be happy to send a pdf or excel file by email if anyone is interested. #16.
