Bit-Check 30 Diamond 1. Bits with small diamond particles on the bit tip. These ensure a good fit in the screw, reduce the required contact pressure and reduce the risk of slipping. BiTorsion bits with an elastic torsion zone, which transfers kinetic energy during peak loads. With a softer bi-torsion zone to prevent the bit tip twisting under high loads. This extends the life of the product considerably. Rapidaptor technology makes it possible to insert bits without handling the socket. The bit is removed simply by pushing forwards. This enables lightning quick bit changes, even with one hand. For mounting in a screwdriver or the chuck of an a electronically controlled drill. The multi-component material of the Bit-Check features a low weight and compact design. The soft material in the lower section of the Bit-Check ensures good bit attachment, while still being easy to remove. The ''Take it easy'' tool finder with colour coding and easy to read markings make it easy to identify the bit profile and size.
