The Wheeler 89-Piece Professional Gunsmith Screwdriver Set covers the wide range of screws you find on rifles, pistols, shotguns and scope mounts. Its hollow-ground flat-blade bits have parallel sides that fill the screw slot and seat flat, instead of the wedge-shaped tip of a hardware-store screwdriver.

A wedge tip rides up out of the slot under torque, which is how gun screws get burred and finishes get scratched. A hollow-ground tip spreads the force across the full slot depth, so you can break loose tight action screws and grip screws without chewing them up.

Features:

• 89 pieces total
• 54 hollow-ground flat-blade bits in a range of widths and thicknesses
• 15 specialty gunsmith bits
• 8 hex (Allen), 4 Phillips and 3 Torx bits
• 2-1/4" shaft extension
• Hex-to-square drive adapter
• S2 tool-steel bits hardened to 56-58 HRC
• Custom-molded storage case

Test-fit the bit in the screw slot before you turn it. The right bit should fill the slot side to side and bottom out without rocking.
