We have now released our NEW and Free drill chart. It contains all Numbered, Fractional, and Letter sized inch drills. As well as basic Metric sizes, Tap Drill charts (Inch and Metric), Taper and Straight pipe threads, Basic Metric Threads, and even Formulas for finding drill sizes for specialty taps. Please take a look, download if you wish, have them printed (18 x 24 inch poster size,) or even hand them out to other people. The only thing we ask is that no changes are made to the chart.
I do plan on making more charts for various subjects pertaining to our line of work. So keep an eye out for anything new.
