The Jackhammer Driver Bit OH-02 is great for large projects where the fastest installation is desired. The Jackhammer Driver Bit OH-02 can be used with HSP-HP (not included) hammer spacer. The jackhammer bit (OH-02) fits a standard 1⅛” jackhammer chuck. After you get it started, you’ll want to attach your post level to make sure you’re going in straight…then continue using the jackhammer until you’ve got it as far in as you want.
