In contrast, many so-called "hollow-ground" screwdrivers with squared-off edges tend to concentrate torque pressure at the square edge of the grind. This design flaw can lead to potential breakage, a risk that any experienced gunsmith would recognize. Standard, straight-tapered screwdrivers also have their drawbacks, as they focus torque pressure on the fine edge of the screw slot. Their tapered design makes them susceptible to being forced out of the slot due to basic principles of physics.

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
