Tap Drill Chart & CNC Speeds

The setup is done, the tool is in the holder, and the only thing left is the number on the control. That is the part this app is for. SPEED AND FEED, WHILE YOU TYPE Change the tool diameter and the RPM moves with it. There is no equals button to miss and no second screen to open. Every result carries the formula that produced it and the document that formula came from, so you can hand the number to anyone who asks where you got it. THE DRILL YOU ACTUALLY OWN Type a thread like 1/2-13 or M10x1.5 and get a drill that exists in the drawer - fractional, number, letter, or metric - with the thread engagement that size gives you. Not the theoretical size. The one on your index. IT KNOWS YOUR MACHINE Enter your spindle's top RPM once. When a cut asks for more than the machine can turn, the number goes red and tells you how far to back the surface speed off. Nobody else on the floor has to catch it for you. TABLES THAT FEED THE CALCULATOR Unified and metric thread tables, tap drill charts, and a right-triangle and sine bar solver that takes degrees and minutes the way your print does. Tap a row and it lands in the calculator. READABLE AT ARM'S LENGTH Numbers sized to read from where you stand, buttons sized for gloves and for a phone inside a bag. No signal needed, ever. No account, ever. WHERE THE NUMBERS COME FROM Cutting speeds are drawn from TC 9-524, Fundamentals of Machine Tools, published by the Department of the Army - a public document you can look up and check. Thread and tap drill data follow ASME B1.1 and ISO 261/965. ONE PURCHASE Buy it once. No subscription, no renewal, no upsell inside the app.
