WERA Insert Bit – Carded Pack of 1 Phillips Tip PH 3 25mm

The WERA Insert Bit is a precision‑engineered screwdriver bit designed for the most demanding professional applications. This single, carded Phillips tip (PH 3) measures exactly 25 mm, making it ideal for medium‑sized screws commonly found in automotive, aerospace, and industrial assemblies.

Key Features

  • BiTorsion® Technology: The bit’s core is built with WERA’s patented BiTorsion design, which distributes torque evenly across the tip. This reduces wear on both the screw and the bit itself, extending service life.
  • DLC‑Coated Diamond Surface: A diamond‑like carbon (DLC) coating provides exceptional hardness and resistance to abrasion. The diamond layer also offers a low‑friction interface, allowing smooth engagement with screws without slipping.
  • Tool Steel Construction: Made from high‑strength alloyed tool steel (grade D 6.3), the bit resists deformation under heavy loads while maintaining precise geometry.
  • Carded Packaging: Each bit is individually carded, protecting it from dust and damage during storage or transport. The card also displays clear identification marks for quick reference.
  • Exact PH 3 Geometry: The tip conforms to the standard Phillips cross‑screw profile, ensuring optimal contact with screw heads and minimizing cam‑out risk.

Applications

The 25 mm length strikes a balance between reach and control. It is perfect for:

  • Installing medium‑size Phillips screws in automotive chassis, engine components, and suspension systems.
  • Securing electrical connectors, panel fasteners, and mounting brackets in industrial machinery.
  • Performing maintenance on aerospace assemblies where precision and durability are paramount.

Compatibility

This bit is compatible with:

  • WERA’s BiTorsion screwdriver handles (e.g., 851/1 BDC SB).
  • Standard magnetic or non‑magnetic screwdriver shafts that accept a Phillips tip.
  • Any tool system that requires a PH 3 insert of 25 mm length.

Performance Highlights

  • High Torque Capacity: The BiTorsion core allows the bit to withstand high torque without bending, making it suitable for tight‑tolerance applications.
  • Low Cam‑Out Risk: The diamond coating and precise tip geometry reduce the likelihood of cam‑out, even under heavy loads.
  • Consistent Wear Resistance: The DLC layer maintains sharpness over thousands of cycles, ensuring reliable performance throughout its lifespan.

Maintenance Tips

  1. After each use, wipe the tip with a clean cloth to remove debris and prevent corrosion.
  2. Avoid exposing the bit to extreme temperatures or chemical solvents that could degrade the DLC coating.
  3. Store the carded bits in a dry environment to preserve their integrity.
