Bosch recently introduced the next generation of Combo Bit drivers. The patented P2+R2 driver bit will run both #2 Phillips and #2 Robertson Square Drive bits without changing drivers. Made from S2M grade steel for durability, the unique tip will engage and securely drive screws with Robertson Square recess, Phillips recess or Combo recess. One bit will drive almost 2/3 of the screws you will ever drive. Available in 1” insert bit singly and in a 15 pc bit set or in a Power style bit in 1-1/2” or 2” length. Made in China.
