The 150mm Extension Bar extends reach for drilling and driving into deep and hard-to-reach areas. It features a HyperTorque™ torsion zone engineered to absorb maximum torque peaks from impact drivers. Its custom alloy has been specifically engineered to provide an optimum blend of hardness and elasticity in high-torque applications. The quick-change head features a strong internal magnet and enables swift changes with ¼” hex shank bits.
The Spade Bits have a wingless design on the tip to ensure less bit-grabbing while they bore into timber. A large scoop and multiple grind edges enhance chip removal and maximise cutting speeds. Both Spade Bits are suitable for electrical and plumbing rough-ins.
Use the 4mm-20mm Step Drill Bit to make holes or expand existing ones in metal/PVC to a specific diameter. Its size markings are laser-etched for enhanced longevity and readability. The titanium aluminium toughened coating minimises heat build-up and prolongs bit life. A HyperTorque™ torsion zone absorbs torque generated from heavy-duty applications. The twin flute design improves cutting efficiency and produces cleaner holes.
The 10-Piece HyperTorque™ Impact Driver Bit Set features 6 x PH2 Impact Driver Bits, 2 x HEX5 Impact Driver Bits and 2 x SQ2 Impact Driver Bits - all in one convenient bit holder with a carabiner for on-person transport. Each one is made from a custom alloy and has a HyperTorque™ torsion zone to handle high-torque applications. Re-engineered tips provide enhanced fastener retention. Each Driver Bit also has a ¼” hex shank suitable for use with drill drivers and impact drivers.
