Brownells #185-9 Magna-Tip Hex Bit

The Brownells Magna-Tip screwdriver is engineered with a true hollow-ground bit, which ensures an even and smooth transmission of torque along the shank. This innovative design not only enhances power transfer efficiency but also guarantees complete metal-to-metal contact between the bit tip and the entire screw slot. This allows for maximum power application, akin to the precision of a finely tapered gun spring. These components are integral to high-speed, production-grade impact drivers, optimized for precision screw setting in large-scale manufacturing environments They must be engineered with an optimal blend of hardness and durability to ensure maximum structural integrity and resistance to wear
