WIDE APPLICATIONS - compatible with power screwdrivers, impact drivers, and other tools that accept 1/4" hex shanks, allowing for quick changing between multiple drill bits and screwdriver bits with just one power tool. suitable for soft metal, woodworking, home improvement, DIY lovers etc;

UPGRADED STRUCTURE - press in pin connection makes the bit and hex shank an integrated structure to prevent break off during drilling, greatly reduced the risk of drill bit snapped off from the hex drive;

ELIMINATES WOBBLING & CHATTER - the final straighten process is added before shipping from the factory. which keep the bit in a straight line during rotation and reduce chatter;
