What chief38 said!

I had to look this one up so that I can belly up to the bar with "The Big Dogs" around here. "Hollow ground" screwdriver tips are the ones that gunsmiths use. Most, if not all, other screw drivers tips are tapered up from the tip. "Hollow ground" tips are not.

I'm a big Craftsman tool guy ("Tim The Tool Man Taylor" vintage) from the 50s. I incorrectly thought that my Craftsman tools would do the job with my firearms. Big mistake! After I buggered one or two screws I was off to Brownells.

All of the firearm screws have both a width and thickness requirement. The Brownells set has all of the combinations that I need, not only for my firearm maintenance, but also for grip screws, and for azimuth and elevation adjustments at the range.
