The Brownells MAGNA-TIP bit #445-2 is designed for a perfect fit with gun screws, providing maximum power transfer and metal-to-metal contact for efficient torque application.
It features a TRUE hollow-ground design which prevents torque pressure concentration that can lead to breakage, unlike standard straight-tapered screwdrivers.
Manufactured for heavy industry, these bits are made for durability and strength, suitable for high-speed, impact-power drivers in mass production settings.
