Parametric Forstner Drill Bit Guide w Collar Stop

A compact drill guide designed for installing magnets flush with wood surfaces, specifically designed for an Irwin 1.5" Forstner bit. The guide features an adjustable collar stop that can be threaded with a 6-32 tap for accurate depth control.

I've included the parametric file so you can easily customize it to work with any Forstner bit. 

Features

• Custom-fit for Irwin 1.5" Forstner bit
• Adjustable collar stop
• Included SCAD files for easy customization of both the guide and collar stop

Notes

• Monitor the collar stop during use - extended friction against the guide can generate enough heat to fuse components
• Customize dimensions via included SCAD files to match your specific bit requirements
• Fit will be tight at first, but will loosen up after a few rotations
•
