• Bits are manufactured to the highest tolerances and specifications for straightness, concentricity and precise tip fit to the fastener
• Bits are manufactured from high alloy steel using the most up-to-date manufacturing process and heat treat to prevent shattering and premature bit wear
• Bits are retained in the bit holder by a set screw that locks securely into a groove on the bit for positive bit retention as well as simple, easy bit replacement
• Broached hex in the bit holder allows higher torque loads
• EYE-D™ markings optimize size visibility
