Re: Hex Broach Options?

We use 3/8" (used in kit transmission, too), 1/2", and 3/4" (used in kit transmission, too). We added the 1/2" to our arsenal this year to drive the shooter wheels.

The 3/4" was expensive (like $400), but the 1/2" and 3/8" are less than one night at the Omni. These broaches will last you a very long time. We do not use keys anymore, just hex broaches and very cheap hex stock.

This solution is a very reliable and maintenance friendly design.
