The Wera Tools 05056400001 is a set of 851/1 BDC Bits, designed for use with Phillips screws. Each bit features a PH 1 x 25 mm size and a 1/4" hexagon drive, which is compatible with the Wera connecting series 1. The BiTorsion zone of the bits absorbs peak loads, reducing the risk of breakage and increasing the service life. The diamond coating on the bits ensures a secure fit in the screw and prevents cam-out. The bits are also color-coded according to profile and size, which makes it easy to find and identify the right tool for the job. Whether you are a professional or a DIY enthusiast, the Wera Tools 05056400001 set is a reliable choice for your Phillips screwdriving needs.

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.
