Product Description This impact-grade security torx bit set is engineered for high-torque fastening. An integrated torsion zone absorbs torque peaks to reduce stress and prevent breakage, delivering up to 10X longer service life than standard bits when used with impact drivers, drills, or screwdrivers. The set includes 24 × 1-inch bits and 12 × 2-inch bits, covering Torx sizes T5–T40, with duplicate T15, T20, T25, and T30 for high-frequency use, plus a magnetic extension for improved access in tight spaces. All bits are CNC-machined from premium S2 alloy steel with a hardened core for strength and toughness. A manganese phosphate coating provides excellent rust resistance, while reinforced magnetism ensures secure screw holding. Compatible with impact drivers, power drills, and manual screwdrivers, this professional torx bit set is ideal for home repair, automotive service, woodworking, and general maintenance.
