Precise fastening with Wera bits

Practical benefits
  • Secure grip prevents slipping: Tiny diamond particles bite firmly into the screw head, so you effectively prevent cam-out and reduce required contact pressure.
  • Enhanced durability under load: The specialized BiTorsion zone absorbs harsh torque peaks, ensuring you experience a significantly reduced risk of premature bit breakage.
  • Standard hex drive fitment: Featuring a standard 1/4" hexagonal connection, you easily mount the bit into compatible holders and drivers for smooth daily screwdriving.

In a nutshell

The right choise for

With the Wera 851/1 bdc Phillips bit 1/4" ph 2 x 25 mm, you achieve maximum fastening control with reduced contact pressure. The fine diamond coating bites securely into the screw head, effectively preventing cam-out and protecting fastener heads from stripping. When driving screws into drywall, wood, or metal, the integrated BiTorsion zone cushions harsh torque peaks, significantly reducing breakage risk and extending bit service life. Thanks to the standard 1/4" hexagon drive, this PH2 bit fits easily into compatible bit holders and power tools for everyday assembly and maintenance tasks.

Product description

High quality bits for Phillips screws with tiny diamond particles on the bit tip. This ensures a secure fit of the bit in the screw, reduces the contact pressure required and lowers the risk of slipping. Comes with Torsion zone where kinetic energy is diverted from peak loads. This greatly extends the product service life; 1/4" hexagon, suitable for holders as per DIN ISO 1173-D 6.3.

  • For Phillips screws
  • BiTorsion zone to absorb peak loads
  • Considerable reduction in the risk of breakage, significant increase in service life
  • Diamond coating for a secure fit in the screw, literally bites into the screwhead to prevent cam-out
  • 1/4" hexagon drive (Wera connecting series 1)

Application

  • Phillips screws

Drive

  • 1/4" hexagon, suitable for DIN ISO 1173-D 6,3 bit holders

Design

  • BiTorsion for long service life, diamond-coated for secure screw fit. Take it easy tool finder: Output colour coding (red = Phillips) and large stamp to enable the desired bit to be easily located.

Features and benefits

  • Particularly when applications involve sensitive materials or high quality surfaces are involved, bits with a diamond coating ensure that work is done safer, faster and at lower cost.
  • Peak forces that occur in power tool applications often result in premature wear of bits or damage to the screw head. This usually occurs during initial power-up and the when the screw comes to a standstill. Screwdriving could become more productive and safer if these peak loads could be minimised. The Wera BiTorsion system prevents premature wear. The service life of the tool is extended and the productivity of power tool applications significantly increased.
  • One of the greatest problems with power tool applications is that the conventional bit easily slips out of the head of the screw (cam-out). This often destroys both the head of the screw and the tool. High resulting costs are incurred e.g. from damaged surfaces and screw connections that can no longer be loosened. Screwdriving will become safer and more economic if this problem of slipping can be minimised.
  • Today, the Wera diamond bit - manufactured with the technology specifically developed by Wera for this application - still sets the standard in terms of resilience and functionality. Wera bits with a diamond coating ensure a secure fit of the bit in the screw head.
  • The minute diamond particles applied to the tip of the tool literally "bite" into the screw and ensure an exact, anti-slip fit in the head of the screw. This secure fit protects the screw. The cam-out forces which compel the user to apply greater pressure to the screw are considerably reduced.
  • Ideal for sensitive materials
  • The optimally coordinated features of the torsion zones on the bit and holder permit a phased yield when under strain. The two-phase system prevents premature wear. Moreover, a long tool service life is also ensured by the hardness of the bits that matches the respective application.
  • Take it easy tool finder with colour coding according to profiles and size stamp - for simple and rapid accessing of the required tool.
