Often called Stone Cutter's Hammers, The Groz Fiberglass Handle Drilling Hammers are ideal for day-to-day requirements of construction professionals. The rugged steel heads are forged from special steel and induction-hardened 50-58 HRC for unmatched durability. The head comes with duly machined and polished faces that are beveled to prevent chipping. The lightweight, yet sturdy dual-injection molded fiberglass handle with a 25% wider neck provides ultimate overstrike protection. The handle comes with a polypropylene jacket and a non-slip TPR grip for vibration and shock absorption. The handle is secured to the head using epoxy adhesive which can withstand rough usage. These fiberglass hammers conform to BS 876 and ASME standards and are used for striking cold chisels, concrete chisels, and brick bolsters, drive-in stakes, rebar into the ground, and break-through concrete floors.
