This Milwaukee SHOCKWAVE Impact Duty Screwdriver Bit Carabiner Set (10 pcs) is built for durability and on-site convenience. It includes ten of the most commonly used bits (Includes : SHOCKWAVE™ screwdriving bits: 10x 50mm length : 2x PH2 / PZ2 / TX15 / 2x TX20 / 2x TX25 / TX30 / TX40) engineered for heavy impact driver use. Each bit is constructed from chrome-molybdenum alloy steel, with a wear-guard, laser hardened tip for superior resistance to wear and stripping. The SHOCKZONE™ geometry allows the bit to flex under peak torque rather than break. All bits are 50 mm length, mounted on a rail, with a carabiner clip so you can hang it from your belt or toolkit for quick access. It’s lightweight but rugged enough for demanding work on building sites, in workshops, or for mobile tool kits.
