I hate it, but I have largely quit breaking them by using G-Wizard. Of course you want to avoid breaking taps. Right now we’re offering a very special deal on our Thread Calculator, so be sure and check it out: The thread calculator includes tapping drill size recommendations with thread percentages for both cutting and form taps. – Tortoise-Hare slider for pinpoint control in difficult materials

– Handles both Form and Cut Tap as cutting tool Here’s what G-Wizard’s Tap Speeds and Feeds Calculator looks like: That’s why we make the G-Wizard Calculator, a serious power tool for folks like you. Quick and dirty calculators like the one above are what you see most often on the web, but most machinists and CNC’ers need more than they can offer. Pro Power Tap Feeds and Speeds Calculator That’s our Tapping Feed Rate, and you couldn’t hope for an easier feed calculator. So if we’re going 1000 rpm and cutting a 20 TPI thread, we need to advance 1000/20 = 50 IPM. It’s our spindle rpm divided by our threads per inch (TPI).

Given the spindle rpm’s the Tapping Feed Rate is just how fast we have to feed to move one full thread per spindle revolution. Tapping Feed Rate & Tapping Feed Rate Formula Given SFM from the table, plus the tap’s diameter, we can calculate rpm with this formula:īTW, that’s from our article on RPM from Surface Speed if you want the details. We can find the recommended surface speed to tap many workpiece materials in this table: For a more sophisticated calculator that will figure that out for you as well as help you find the right TPI value and work in Metric, keep reading! Recommended Surface Speeds (SFM) by Material The spindle speed depends upon the material you’re trying to tap and the diameter of the tap. Everything starts from Tapping Speeds What Tapping RPM or Tapping Speed Should I Use? Tapping Feeds and Speeds are pretty easy to calculate because they’re constrained by the thread that is being tapped.
