About this item
  • [Premium S2 Alloy Steel & Heat Treatment ]โ€“ Crafted from industrial-grade S2 steel, these bits undergo specialised thermal processing to deliver outstanding impact toughness and high-torque endurance. The hardened structure resists deformation, chipping, and premature wear even under sustained heavy loads, making them reliable for workshop, garage, and on-site tasks.
  • [Strong Magnetic Fixation ]โ€“ Each bit is equipped with a built-in rare earth magnet that firmly holds screws onto the tip during positioning and driving. This anti drop feature enables single handed operation in tight or overhead spaces, significantly improving workflow efficiency and reducing lost fasteners.
  • [Complete Star Profile Range (T7โ€“T40)] โ€“ The 10-piece set covers every common star size from T7 to T40๏ผˆT7, T8, T9, T10, T15, T20, T25, T27, T30, T40๏ผ‰, with each bit measuring 50mm in length for excellent reach. Included is a 75mm impact rated extension holder/adapter that converts standard drivers into deep access tools, ensuring you have the right fit for automotive panels, engine components, electronics, and household appliances.
  • [Precision Machined Tips & Anti Slip Shank] โ€“ The tips are finely ground to exacting tolerances for a snug, cam out resistant engagement with fastener recesses. The shanks feature strategically placed anti slip grooves that enhance grip when using pliers or quick change chucks, while yellow laser engraved size markings allow instant visual identification, saving time during busy jobs.
  • [Versatile Impact Ready Performance] โ€“ Designed to withstand the punishing torque of impact wrenches, pneumatic drivers, and cordless drills, this set excels in automotive repair, machinery servicing, metalworking, and heavy duty DIY projects. The shock absorbing adapter prolongs bit life by dissipating peak forces, ensuring consistent performance across thousands of cycles.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days โ€” so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
