The Bahco 66IM/54C-1 Impact Bit Set features a comprehensive selection of bits designed for use with impact drivers and demanding applications. Engineered for durability, the integrated torsion zone effectively distributes force concentration, enhancing longevity. Each bit is crafted from high-performance alloy steel with a manganese phosphate finish. The torsion zone is optimized to absorb torque peaks and resist sudden impacts, preventing premature tip breakage and extending service life. This set is supplied in a robust, glass-fiber reinforced case with a patented 180 locking function, ensuring the case remains open even when inverted (supporting up to 500g) without risk of accidental closure. Swiveling racks provide efficient space utilization and easy bit access. The lid and body of the case can be separated for adaptable organization within tool trolleys or drawers. A personalization sticker is included.
