20Pc Impact Hex Allen Key Drill Bit Set - Metric & Imperial S2 Steel

Professional 20-piece impact hex drill bit set designed for demanding fastening applications. This comprehensive set includes both metric and imperial sizes, making it perfect for home repairs, automotive work and professional trades.

S2 Alloy Steel Construction
Features CNC machined drill tips and hardened S2 alloy steel bodies for superior strength and durability. The manganese phosphate surface coating prevents rust and extends tool life, even with heavy use.

Impact-Ready Design
Built with a torsion zone that absorbs torque peaks and reduces breakage. The 1/4 inch quick-release hex shank fits impact drivers and heavy-duty screwdrivers. Strong magnetic tips hold screws securely and won't lose magnetism over time.

Complete Size Range
Each 50mm bit provides excellent reach and control. Set includes 10 metric sizes (1.5mm to 8mm) and 10 imperial sizes (5/64" to 5/16"), covering virtually all common hex fasteners.
