The Wheeler 89-Piece Professional Gunsmith Screwdriver Set covers the wide range of fasteners found on firearms with hollow-ground bits that seat flat in screw slots. The hollow-ground tips fill the slot to reduce burring and slipping on gun screws.

Features:

• 89-piece bit set
• 54 hollow-ground flat-blade bits
• 15 specialty gunsmith bits
• 8 hex (Allen), 4 Phillips, and 3 Torx bits
• 2-1/4" shaft extension and hex-to-square drive adapter
• S2 tool-steel bits, 56–58 HRC
• Custom-molded storage case

The hollow-ground flat-blade tips fit screw slots without burring the fastener.
