Rare earth neodymium magnet is 2x stronger than magnets in standard insert bit holders. Xtreme torsion technology is engineered to allow the torsion section of the bit holder to flex under load, taking pressure off of the bit tip for increased durability in high torque applications. 2 piece design is engineered to allow the torsion technology to fully activate. High quality steel engineered for use with impact drivers. Designed exclusively for high torque impact drivers. ›See more product details. Imported from USA. 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 with high-strength steel for longer life. The impact GOLD ultra-magnetic insert bit holder (B-35097) features Xtreme torsion technology, which allows the torsion section of the 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 rare earth neodymium magnet is two-times stronger than magnets in standard insert bit holders, so users get the added convenience of one-handed fastening. The Makita impact GOLD ultra-magnetic insert bit holder is ideal for use with impact GOLD insert bits (sold separately), and is engineered for driving screws in a wide variety of demanding applications including deck building, framing, installing plywood subfloor, and more.
