About this item
  • JIS B4633 Standard : Adhering strictly to the Japanese Industrial Standard (JIS B4633), these JIS Impact Bits are expertly engineered to tackle the toughest fasteners found on iconic Japanese vehicles—such as Honda, Yamaha, Suzuki, and Kawasaki—while preventing stripped screws and equipment damage to extend your vehicle’s service life.
  • Premium S2 Steel : Crafted from high-grade, hardened S2 steel, these JIS Impact Bits deliver exceptional strength, durability, and superior impact resistance. Their specialized design effectively absorbs high-torque pulses and shocks, ensuring reliable performance in heavy-duty applications and significantly outlasting standard bits.
  • Effortless Removal of Stubborn Fasteners: These heavy-duty JIS Impact Bits are meticulously designed to break free rusted, corroded, and over-tightened fasteners that ordinary bit sets cannot handle, ensuring a smoother and more efficient repair process.
  • Secure 5/16″ Hex Shank for a Reliable Connection: Equipped with a precision 5/16″ hex shank, these JIS Impact Bits offer a secure, slip-free fit with most mainstream manual impact drivers—including popular brands like TEKTON, Capri Tools, and CRAFTSMAN—optimizing power transfer and minimizing cam-out.
  • Complete 75mm Impact Bits Bundle for Versatile Repairs: This comprehensive set features a total of four bits, including three 75mm JIS Impact Bits and one slotted impact screwdriver bit, perfectly suited to meet a variety of fastening needs in motorcycle and automotive repair applications.

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 — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
