Do you refer to Machinery’s Handbook a lot for the quick reference charts? Do you use online Calculators of various kinds to figure out your machining problems?
I used to, but then I got tired of leafing through thick handbooks and trying to find things on the web at the last minute. Yes, they’re great resources, but I wanted things to be a lot closer to my fingertips. I wanted a higher concentration of useful tools.
To make that happen, I started building what would eventually become this page. I hope you get as much use out of all these free resources as I have. One thing you’ll notice is most of the free calculators are built right into our G-Wizard software. That’s no accident, but you’re probably wondering how something built into a piece of paid software can be free? I’m glad you asked!
If you do the G-Wizard free 30-day trial, when it ends, you’ll still have access to all the free calculators. The only thing you lose if you choose not to buy at the end of the trial are the Feeds and Speeds-related functions. That still leaves a huge amount of territory–useful time saving tools that are listed below.
Feeds and Speeds

Lumber Sizes: Ever notice a 2 x 4 doesn’t measure 2 by 4 inches? Here’s the scoop on the actual sizes for lumber, despite what we call it. There’s even a free calculator for weights and volumes based on the actual sizes.
Sheet Metal Wire Gauge Sizes
Sheet Metal Wire Gauge Sizes Chart / Table and Calculator: Sheet metal gauging is somewhat arbitrary, but we’ve got full reference charts plus a nifty free calculator to help right here.
Surface Finish Chart Tables
Surface Finish Chart Tables: Complete Guide to Surface Finish Charts, RA, RZ, Measurements, Callouts and Symbols.
Drill Feeds and Speeds Calculator
Drill Feeds and Speeds Calculator: A quick free calculator for drilling feeds and speeds. Plus an advanced industry-leading feeds and speeds calculator for more serious work.
Yup, it’s true, you got this far and didn’t find the information you were looking for. Happens to the best of us. When all else fails, I always turn to Machinery’s Handbook to look for information.
One more sneaky trick: buy one or two editions back–not the latest. Most of the info hardly changes and you’ll save a bundle!
