    Tips: Advantages of rotary hammer conjoined gearbox design.

    • Effectively prevent oil leakage of rotary hammer body.
    • For the non-conjoined gearbox, due to screws connection, its case is easy to loosen after working for a long time. The conjoined design solves this problem.
    • Conjoined design shortens the length of joint and avoids easy breakage.
    • Connectors are small, making rotary hammer easy to disassemble and repair.

    How to make the rotary drill jam the drill bit
    How to put the drill bit in the rotary drill? I operated for a few hours, but it couldn't block the drill bit at all.
    A manager responded to this review
    The rotary drill does require a special SDS carbide drill, which has three grooves on the shank. I pull back and press lightly on the drill bit and it will slide into the drill bit. Then, rotate the bit to make sure it is locked in place so that the operation can jam the bit.
