ABSTRACT:
A power tool having a low frequency reduction apparatus includes a first handle portion, a second handle portion, and a dual-density bladder disposed between the first and second handle portions. By disposing such bladder accordingly, the second handle portion is effectively isolated from the first handle portion, thus reducing the low frequency vibrations transmitted to the second handle portion. Preferably, a gap is formed between the first and second handle portions.
