STRIKING TOOLS
Why GROZ Hammers ?
In our desire to build the world’s strongest Hammer, we tested our Indestructible Handle Sledge Hammer against Sledges with different handles. We attached each Sledge to an Electronic drive machine & tested for both Direct & Overstrikes at a strike rate of 80 blows per minute.
Testing of Hammers
WOOD HAMMER : BROKE IN 450 STRIKES IN DIRECT STRIKE TEST & 208 STRIKES IN OVERSTRIKE TEST
FIBRE GLASS : HAMMER BROKE IN 7,000 STRIKES IN DIRECT STRIKE TEST & 4,126 STRIKES IN OVERSTRIKE TEST
GROZ HAMMER : WE STOPPED COUNTING AFTER 36,000 STRIKES WITH NO INDICATION OF DEFORMATION IN BOTH DIRECT & OVERSTRIKE TESTS
Specialty in GROZ Hammers
- STEEL LOCKING PLATE : locks head to the handle eliminating loosening or dislodging
- HI-VISIBILITY HEAD : instant identification on any job site
- VULCANIZED RUBBER HANDLE : Absorbs impact & vibration, reducing user fatigue. Protects user in the event of striking an electrical wire. Made from special grade of ozone resistant rubber for use in tough outside environments. Handles on most head sizes weigh more than the head, allowing user to apply double the torque on any struck surface.
- DROP FORGED HEAD : with striking ends induction hardened. (50-58 HRC)
- SPRING STEEL BARS : 9/32" (7.1 mm) dia. spring steel bars resist overstrike without breaking
Type of Hammers
Indestructible handle is made up of 4 spring steel bars that run all the way through the handle. Bars are locked with the hammerhead using steel locking plates ensuring that the head never gets dislodged. Ergonomic rubber grip handle absorbs vibration and reduces fatigue. Special bonding process ensures that the head never gets loose from the handle
These are available in 2 types:
Heavy Duty 50-58 HRC Head Forged from special steel, the hammer head is induction case hardened 50-58 HRC. These hammers are especially useful in demolition work where the struck surface is softer than the hammerhead.
Soft Face 30 HRC Head Forged from special steel , the hammer head is induction case hardened & then tempered to reduce hardness to within 30-35 HRC. Softer head is designed to mushroom when striking harder base materials. Prevents damage to struck work pieces.
- Do not strike objects harder than 46 HRC. Striking items of a greater hardness is liable to cause fracture or chipping
- WORKING TEMPERATURE RANGE : –10°C TO 50°C (14°F TO 122°F)
