The masonry fixings and installation set is one of the first of its kind to be used with an impact driver. It includes a combination of drill bits and screwdriver bits all from Armeg's Twister range of impact rated accessories. All bits within this unique set feature a 1/4" quick change shank making changing bits very quick. The range of Twister masonry bits features a precision ground cutting edge which reduces the torque on the drill bit; this in turn makes for faster and more efficient drilling. These bits can be used to drill through a wooden batten as well as the wall at the same time, so no need to change bits for the different materials. The Twister screwdriver bits come in 50mm and 75mm lengths and feature Armeg’s torsion portion design, which allows for up to 133% increased flexibility over a standard bit. This increased flex absorbs more of the torque and in doing so reduces the stress on the tip, providing greater durability when used with impact drivers. The 15 piece set comes in a handy fabric roll.
