Head is induction case hardened to 52 HRC for extended life.
The TMR 10lb Bead Breaker Hammer is 75 times stronger than wood and fiberglass; made of steel bars that run all the way through the handle and locked with the hammerhead using steel locking plates ensuring the head never becomes dislodged or loose. Dual injected fiberglass ergonomic rubber grip handles absorb vibrations and reduces fatigue that will not break.
