853/4 ACR® bits

High quality bits with Torsion zone – where kinetic energy is diverted from peak loads. This greatly extends the product service life. Come with rough ribs (anti cam-out feature, ACR) to prevent any slipping out of the screw head. Tough viscous for universal use. 1/4" hexagon, suitable for holders as per DIN ISO 1173-F 6.3.
