Tool-setter

High-Precision Tool Setter for CNC Machines

This precision-engineered tool setting instrument is designed to play a critical role in CNC machining—providing accurate Z-offset measurement by sending a reliable output signal directly to your controller. It ensures your spindle bits are properly referenced, enhancing both accuracy and repeatability in your workflow.

What’s Included

Your choice of Tool Setter:
- Metalworking (Black) or Woodworking (Gold/Yellow)
6 ft cable with a GX12 4-pin connector pre-attached
- Includes 2 ft of metal-sleeved protection for durability inside the carving area

Optional Add-On

Want easy integration with your controller? Add our Tool Setter Cable Inlet, featuring:

A GX12 4-pin panel-mount connector
12" of 22AWG wire with ferruled ends for clean, secure installation

Compatibility Notes

Masso Users:
Tool setter inlets connect directly to terminal blocks on Masso systems—not via Molex connectors used on Onefinity Elite.
All PwnCNC accessories are tested and supported on Masso G3 and Masso Touch controllers. For other controller types, compatibility is not guaranteed—though we're happy to help where possible and will update the listing as we learn more.

Tool Setter

I picked the metalworking tool setter up with my conversion kit. Once dialed in works great!

Very accurate not quite straight.

I wanted to use this to set my z axis offset. It was very repeatable, down to the accuracy of my machine ~.0002 inches. Unfortunately the surface wasn't parallel with the base. It was out a few thousands. There are 4 adjustment screws in the base to help compensate, but those really wouldn't work for my application. I wound up 3d printing another base, screwed it onto the tool setters base and used the adjustment screws to get the surface parallel to the new base. It came out off by ~.0004 inches from edge to edge. I think if I had an aluminum base instead of 3d printing one I could have done a little better. All in all with a little work I have an incredibly accurate tool for a budget tool price.

Tool Setter

I ordered the PWN CNC Tool Setter to replace a lower profile tool setter I already had. Now that I'm running the ATC system I don't mind having such a tall protrusion sitting right in line with the tool trays.

As a bonus they were out of stock on the woodworker version and an added benifit of the metal working is the air blast function to clear debris from the top of the tool setter. This works well with the ATC system even though it's unlikely to get enough dust on it to be an issue!

This metal working tool setter is awesome!

I chose the metal working tool setter and am super happy with it. I don't work with metal, but I figured the extra accuracy would be great, even for my wooden signs and plaques. I have no complaints at all, and it's easy to install. I also made an installation video that you may find helpful; check it out!
