The Bottleneck Nobody Talks About

Every machine shop has this problem. Most just accept it as part of the job.

Without ToolProof
  • 7 machinists sharing 3 computer stations
  • 20 minutes waiting just to check your tool list
  • Hovering over every blue toolpath line in Mastercam to find the deepest ball-mill cut
  • Handwriting notes that get smudged, lost, or wrong
  • Missing a tool change buried on line 4,000
  • Scrapped parts, crashed tools, wasted time
With ToolProof
  • Tool list in 10 seconds flat
  • No computer station needed, runs on any PC
  • Deepest Z per tool, including ball mills, without scrubbing the toolpath
  • Every tool, every Z-depth, every time
  • Auto-detects files from USB drives
  • Print or export your list and walk to the machine

What ToolProof Does

Everything you need to verify tools before you run the program.

Instant G-Code Parsing

Drop any posted program, get the full tool list in seconds. Supports Mastercam, Alphacam, Fusion 360, GibbsCAM, and more.

Deepest Z per tool, instantly

See the maximum depth for every tool, including ball mills doing surface-finish flowlines. No more hovering over toolpath lines in Mastercam to find the lowest point.

Auto-Watch Mode

Set ToolProof to watch a folder or USB drive. The tool list pops up the moment a new file appears. No clicking required.

Works Completely Offline

No internet, no cloud, no account, no login. Runs on your machine, your data stays on your machine.

Export & Print

Export to PDF or print the tool list directly. Grab it and walk to your machine.
