Brownells Magna-Tip Super Sets?

Every gunsmith knows no two screw slots are ever exactly the same. Because so many factories use outside vendors for screws, slot sizes can vary, even within the same model of gun. If you want to be professional about your work, you custom grind each bit to the correct size, a frustrating and time-consuming task without a Super Set. The Super Set comes in graduated 22-bit, 44-bit, and 58-bit configurations, so you’ll always have a screwdriver blade that precisely fits the size and width of virtually any screw slot. You get flat blades in 9 different widths from .120" to .360", each with four to six blade thicknesses from .030" through .070" in .005"or .0 Mfg: Brownells SPECS: Bits: Slotted- 1 1/2" (3.8cm) long.
