This versatile set combines high-quality screwdriver bits, drill bits, and useful adaptors to tackle a wide range of fastening and drilling applications on site. Engineered specifically for impact driver use, the screwdriver bits feature a shock-absorbing torsion design that increases torque performance whilst protecting against premature wear.

Each bit features a blackened hex shank with shot blast finish and highly visible laser-etched size markings for quick identification. The set includes an extensive selection of 25mm and 50mm PZ and PH bits in the most commonly used sizes, plus TX-STAR® bits, hex bits, and three titanium-coated HSS drill bits. The magnetic bit holder and nut runners enhance productivity, whilst the square drive adaptors provide excellent versatility for socket work. All components are housed in a robust dual-injected plastic case that protects your investment and keeps everything organised.
