Makita Impact GOLD® is innovation in fastening with a full line of insert bits, bit holders, nutsetters, socket adapters, and more. Impact GOLD® is designed exclusively for use with high-torque impact drivers, with high-strength steel for longer life, and a precision-fit tip engineered to prevent "cam-out" and stripping. The Impact GOLD® Ultra-Magnetic Insert Bit Holder and bits feature Xtreme Torsion Technology, which allows the torsion section of the bit and bit holder to flex under load and take pressure off of the bit tip for increased durability in high torque applications. The two-piece design is engineered to allow the torsion technology to fully activate. The set also includes high-strength 6-point sockets made from heat-treated alloy steel, with black oxide coating to resist corrosion. When used with an impact driver (sold separately) the Makita Impact GOLD® Ultra-Magnetic Insert Bit and Impact Socket Set is ideal for a wide variety of driving and fastening applications.
