About OnlyCNCs

An essential tool we needed make for the community.

Welcome to CNCs Only

Frustrated with poor material with breaking bits, ruining stock, and time wasted on unreliable feeds and speeds charts, we built the ultimate CNC machining calculator. Whether you're cutting for fun, profit, or both, we believe you deserve pro-level results without needing a machining degree. Built for hobbyists, refined for precision.

Our Mission

To empower the desktop CNC community with tools that take the guesswork out of machining — and put the creativity back in.

Key Points

Making CNC easy

Lets take away the stress

One of the top two reasons people give up on CNC woodworking with desktop machines is because they struggle with dialling their machine in. This takes the stress out of that part of the process and gives you a starting point to dial your settings in.

For the makers community

Its not about the money

The makers community gives so much to so many people. And we understand that buying a machine, software and bits can be expensive so wanted to develop a tool that was free and available to all.

Supported by great CNC brands

They want to see you succeed!

The brands of the CNC world know the struggles of makers - because most of them are makers themselves. Which is why they have been kind enough to sponsor this project and bring it to life - Thank you to the sponsors.

Your feedback is essential

Its taken a lot of effort to build up this platform and data, but the reality is that its very difficult to try and account for every machine, every setup, every variable. That’s where we need your help. If something feels too slow or too fast, use the feedback function and let us know. Your feedback helps everyone else.
