We obsessed over G-Wizard
Speeds and Feeds Calculator for Lathes:
It took years, we analyzed data from over 250 tooling catalogs,
we built a powerful cutting physics engine with advanced
algorithms that consider almost 60 different variables,
we added AI Machine Learning algorithms,
and we worked with over 100,000 CNC'ers

Better Tool Life, Surface Finish, and MRR with G-Wizard
Master your Speeds and Feeds the easy way with G-Wizard.
"I've been asking for this for 30 years from the CAM guys. This program is the ‘go-to' source for feeds and speeds" Ed
How much do you spend on cutters in a year? If each one lasted 56% longer, you'd save 56% of that. Plus what's the value of your time saved and time saved on jobs?
G-Wizard pays for itself very quickly-you'll see in the 30-day Free Trial.
G-Wizard Speeds and Feeds Calculator
Lathe Features:
Get Speeds and Feeds in seconds
Getting good Speeds and Feeds is quick and easy: Fill in the blanks left to right, top to bottom and G-Wizard instantly returns the best Spindle Speed and Feed Rate.
Super simple for Beginners, powerful and flexible for Pros. Plus, the best training materials anywhere free with the product.
Figure the Best Cut Width and Cut Depth
How do you know when you've got the best Cut Depth and Cut Width? These two parameters matter more than almost any other for best Speeds and Feeds. G-Wizard will find the best value for your insert based on its size, shape, and lead angle.
Adjusts to Your Needs
Are you looking to maximize tool life or material removal rates? Do you have a small CNC machine or a big industrial machine? Are you trying to hog out a bunch of chips or achieve the best possible surface finish?
G-Wizard makes it easy to dial in exactly the results you are looking for.
CADCAM Wizards: An Expert in the Box
How often do you get to experiment with hundreds of different feed and speed combinations to find the best one for your job?
CADCAM Wizards will do that for you automatically in a matter of seconds and without asking too many questions. It's like having a machining expert sitting at your shoulder telling you the right combination for the win-another G-Wizard first!
Extensive Tool Crib & Tool Coverage
G-Wizard Calculator handles more different kinds of tooling than any other Speeds and Feeds Calculator. Import and Export tables from CSV files, use Manufacturer's Recommended Data, define tool geometry, and use dozens of tool types for Mills, Routers (special router cutters handled) and Lathes. End Mill Speed and Feed: Coatings (including PCD) & Geometry (Ballnose, Upcut, Downcut, Compression, and more) Drill Feeds and Speeds: Carbide, HSS, and Parabolic Turning and Lathe Tools Reamers, Saws, Woodruff Cutters, Corner Rounders, Tapping, Thread Mills, and Boring Heads
Giant Material Database
Metals of all kinds, plastics, composites, even hard to find materials like Tungsten, Cobalt Chrome, and Graphite.
Plus, we add new materials on request.
Speeds and Feeds Charts: Obsolete
Throw away those old speeds and feeds charts and pdfs.
A chart is only 2 dimensional. It takes multiple charts to cover maybe 3 or 4 dimensions. They give you ranges that are tough to interpret when you just want the answer.
G-Wizard's cutting physics engine considers nearly 60 variables. No chart will ever do that!
G-Wizard Works for Your CNC Machine
G-Wizard has a giant database of pre-defined CNC Machines, plus it's super easy to do your own machine definitions. We'll even create new machine profiles upon request, completely free of charge.
G-Wizard works for your CNC Machine!
Expert Tips
You ever read all those great tips in the tooling catalogs?
When to start peck drilling or switch to parabolic flutes.
All those tips are wonderful, but who can remember it all?
G-Wizard will remember them for you. It even has a comprehensive Cheat Sheet to help you bend Feeds and Speeds to your special needs.
Machinist Calculators Need Reference Information Too
Trig Calculators, Threads, Fasteners, and More
Why leaf through old-style handbooks when you can have interactive calculators at your fingertips?
Bolt Circles, Trig, Chords, Thread Database, Fastener Dimensions, and much more. There's even a Turner's Cube calculator!
G-Wizard isn't just Speeds and Feeds, it has the most comprehensive reference resources available in any software package.

"I'm in my 27th year and seen my share of ‘machinist aid' software and this BY FAR packs the most punch for the dollar. Shop owners would be fools not having a copy." Michael
"I'm a total Newbie on hobby mill and had the crazy idea to jump right in on some plasma cut hardened steel. WOW! I did it and could not have done it without G-Wizard. I completed our very first EVER customer part in about 1 hour." Jeffrey
"I am amazed at all the data that is available when using the G-Wizard. I've been in the business for 43 years and sure wish something like this was around back in the day." Michael
Over 100,000 machinists from thousands of companies
have used our software. We hope you will too.
