This tool boasts wide application compatibility, being suitable for power screwdrivers, impact drivers, and other tools that accept 1/4 in. hex shanks, allowing for rapid bit changes among various drill bits and screwdriver bits with just 1-power tool. Its structure has been upgraded, featuring a press-in pin connection that integrates the bit with the hex shank to prevent breakage during drilling, significantly reducing the risk of the drill bit snapping off from the hex drive. Furthermore, an additional final straightening process eliminates wobbling and chatter during rotation, ensuring a straight path for the drill bit. Designed with a unique 135° split point, these bits stay centered without the need for a pilot hole, and the fully ground body drills faster with fewer defects, exhibiting excellent chip and heat removal capabilities.
