Roughing Drill Information:

Proper chamber preparation is critical for reamer life and finish quality.
If you are starting from a blank or un-prepped barrel, we strongly recommend using the appropriate

chamber roughing drill

prior to finish reaming.

Using a roughing drill removes the bulk of the material, reduces cutting load, and helps produce a cleaner, more consistent finished chamber.
