Reliable fastening with Wera

Practical benefits
  • Prevent slips and cam-out: The diamond coating bites directly into the fastener head so you avoid slipping while driving screws.
  • Extended bit service life: An integrated torsion zone absorbs peak loads, protecting your bits from premature wear and breakage.
  • Fast one-handed bit changes: The included quick-release bit holder lets you insert and swap bits rapidly with a single hand.

In a nutshell

The right choise for

Take full control of your fastening tasks with the Wera Bit-Check 12 Diamond 1 sb bit set. Tiny diamond particles on the bit tips bite firmly into the screw head, significantly reducing cam-out forces and preventing slips. Thanks to the BiTorsion zone, peak loads are effectively absorbed to extend the service life of your bits under demanding use. The included 1/4" Rapidaptor universal bit holder lets you swap between the eleven Phillips, Pozidriv, and Torx bits quickly with one hand. Whether working on-site or in the workshop, you complete every job with precision, speed, and confidence.

Product description

Bits with tiny diamond particles on the bit tip. This ensures a secure fit in the screw head, reduces the contact pressure required and lowers the risk of slipping. BiTorsion bits with a torsion zone - where kinetic energy is diverted from peak loads. This greatly extends the product service life. Comes with Rapidaptor technology, which allows bits to be attached without any need to actuate the sleeve. The removal of the bit is simple, just by pushing the sleeve forward - for rapid bit change with just one hand. For insertion in the power screwdriver or into the chuck of the power drill. The multi-component Bit-Check is convincing on account of its low weight and the maximum possible degree of compactness. In this respect, the soft material in the lower section of the Bit-Check ensures that the bits are securely held whilst being simple to remove at the same time. The profile and size of the bits are easy to recognise thanks to the Wera Take it easy Tool Finder with its colour coding and clearly visible imprint.

  • Upright positionable Bit-Checks convince due to their functionality in a minimum of space
  • BiTorsion bits for long service life
  • Diamond coating for a secure fit in the screw, literally bites into the screwhead to prevent cam-out
  • Rapidaptor holder for rapid bit change
  • Take it easy tool finder: colour coding according to profile and size
1 bit holder Rapidaptor with quick-release chuck, 11 BiTorsion bits for long service life, diamond-coated (BDC) for secure screw fit. The Take it easy Bit-Checks have bits with a sleeve which - from its colour and size designation - make it simple to access the right bit quickly.

Features and benefits

  • The Bit-Checks can be positioned upright at the workplace so the tool is always quickly to hand.
  • 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.
  • The diamond coating of the DC bits lowers the danger of slipping as the minute diamond particles literally "bite" themselves into 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
  • Lightning-fast bit change without any extra tools. One-handed operation. With fast-rotating sleeve for easy wielding of the screwdriver.
  • Bitholders, magnetic, for easier application of the screw
  • The Take it easy Bit-Checks have bits with a sleeve which - from its colour (e.g. red = Phillips) and size designation - make it simple to access the right bit quickly.
