The Wera 05134944001 is a high-quality bit designed for Phillips screws. It features a sharp-edged profile that breaks away paint when screw profiles are covered in it, ensuring a dependable transfer of power between the bit and screw. The diamond coating provides a secure fit of the bit in the screw, reducing the contact pressure required and lowering the risk of slipping. The bit has an extra-hard design and a ¼" hexagon drive, making it suitable for holders as per DIN ISO 1173-F 6.3.

A stands for aviation. A bits are particularly hard bits with a sharpedged profile which e.g. penetrates screw profiles full of paint (such as on fuselage panels) ensuring a dependable transfer of force between the bit and the screw.

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.

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.
