Makita impact GOLD is new 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, and is engineered to last up to 60x longer than standard insert bits. Impact GOLD insert bits feature Extreme torsion Technology, which allows the torsion section of the bit to flex under load and take pressure off of the bit tip for increased durability in high torque applications. High-strength steel delivers longer bit life, and the precision-fit tip is engineered to prevent "cam-out" And stripping. Makita impact GOLD is designed exclusively for use with high-torque impact drivers, and it is ideal for the most demanding jobs including deck building, framing, installing plywood subfloor, and more.
