The Micro-Pro insert tool is designed as a solution to the smaller shaper. It is available in a variety of widths: 35mm, 40mm, 50mm,and 60mm, to accommodate most profiles that you might need. They are available with bore sizes from ¾” To 1-1/4” diameter. Micro-Pro is made of7075 aircraftaluminum to reduce weight for smaller arbors.
This beast can handle all of the same things you would expect from the Multi-Pro, but it is best suited for a machine that has a smaller spindle size than most. Weight can become an issue with those. If you run a small shop and have small equipment, than this is the best thing for doing your work. It's solid, accurate, and easy to use.
