Description

25mm Impact Torsion Bit – Compact Power for Precision Work

This 25mm impact torsion bit delivers the durability and precision your shop needs for high-torque fastening in tight access areas. Engineered from S2 steel with a manganese phosphate finish, it resists corrosion and maintains hardness under repeated impact loads. The short length makes it indispensable for confined spaces where standard bits won't fit—a must-have for any professional toolkit. Pair it with longer-reach torsion bits for a complete fastening solution across all depths.

Key Features

  • Material: S2 tool steel—proven impact resistance and edge durability
  • Finish: Manganese phosphate coating—corrosion protection and reduced friction
  • Length: 25mm—optimized for compact work areas and recessed fasteners
  • Hex Shank: 1/4-inch drive—compatible with all standard quick-change holders and impact drivers
  • Torsion Neck: Engineered flex zone absorbs shock and prevents bit breakage during heavy-duty fastening
  • Driver Tip: Precision-ground for secure fastener engagement and minimal cam-out
