Insert bits feature a compact design, and power screwdriver bits are longer for higher torque and hard-to-reach applications. Both are designed for easy change-out in production use. A double-end drill bit set can offer the versatility of Phillips and slotted ends. Find torx, hex and square-recess screwdriver drill bits, too.
