MacroBOHR Boring Tools - Range 8.661" to 40.157"

The MacroBOHR boring system is a lightweight line of tools optimized for large diameter boring.

All toolholders, boring heads, & counterweights are made from high-strength aluminum or nickle-chrome alloy. The boring heads are fully indexable on the plates and very easy to setup.


Maximum Boring Range

Boring holes from 8.661" up to 40.157" can be achieved by simply changing the plate size. Each plate has 2 radial positions to locate the boring head and counter-weight to achieve minimum or maximum bore size.

Use MacroBOHR for finish, rough, and external boring applications. External boring is achieved by reversing the cartridge position.
