Product Description

With Brownells MAGNA-TIP screwdriver it is now possible for the gunsmith and firearms hobbyist to have a close fit in most any gun screw he will encounter - and darn near everything around the house and garage too.DESIGN OF BITSThe TRUE hollow-ground bit transmits all the energy of twist (torque) evenly and smoothly up the shank of the bit. Not only does hollow grinding permit this power transfer it also gives complete metal-to-metal contact between the tip of the bit and the entire screw slot. Thus maximum power can be exerted as in a finely tapered gun spring.So-called "hollow-ground" screwdrivers which have been dubbed off square result in all torque pressures con Mfg: Brownells
