Shockwave-impact accessories is the system solution in the area of ​​impact driving. The innovative system accessories is not only impact resistant and therefore suitable for use with impact wrenches, but also provides for all drilling and bolting the right accessories. Shock Zone Geometry. The flexible zone in the screwdriver Shock reduces the load on the bit tip, thereby the risk of breakage. The combination of the shock zone and a special hardening process absorb the blows. The Shockwave bit tip is not milled, but cold forged, which makes for a higher material strength and exact fit and guarantees optimum power transfer to the screw head. Special steel: Designed for Milwaukee steel alloy is specially designed for use with impact wrenches. The bits are thus more durable and yet flexible - ideal for hard screw driving.
