ATD Tools 55101 Phillips #2 x 5" Torsion Impact Screwdriver Bit

The ATD Tools 55101 is a Phillips #2 x 5-inch Torsion Impact Bit engineered for professional-grade fastening applications. The extended 5-inch length provides added reach in tight or deep access areas where standard-length bits fall short, making it an ideal replacement or upgrade for use with power drills and impact drivers.

ATD's torsion design allows the bit to flex under load, absorbing the shock and torque spikes generated by impact drivers. This protects both the bit tip and the fastener head from premature wear, stripping, and breakage — extending the service life of the bit significantly compared to standard non-torsion bits.

Key Features:

• Phillips #2 tip — fits the most common screw head size used in automotive, construction, and general assembly
• 5-inch extended length — ideal for deep access and hard-to-reach fastening locations
• Torsion zone design — flexes to absorb impact shock and reduce fastener stripping
• Impact-rated construction — engineered to withstand the high torque loads produced by impact drivers
• CNC precision machined tip — maximizes engagement with fastener recess for longer bit life
• Heat-treated steel — provides durability and toughness under demanding conditions
• Manganese phosphate coating — resists corrosion for long-term tool storage and use
• 1/4" hex shank — compatible with all standard quick-change power tools and impact drivers

The ATD 55101 is also a factory replacement component included in the ATD-551 50-Piece Torsion Impact Bit Set. It is sold individually for convenient single-bit replacement without purchasing a full set.
