GEARWRENCH 56 oz. Shock-Absorbing Dead Blow Hammer Unit Only (GWHDB56)

56 oz. Dead Blow Hammer The GEARWRENCH GWHDB56 is a 56 oz. dead blow hammer engineered to deliver controlled striking force while minimizing rebound through a steel shot-filled head. Designed for automotive technicians, industrial maintenance professionals, mechanics, fabricators, and equipment service trades, its shock-absorbing construction maximizes impact transfer while reducing bounce-back during demanding striking applications. Best Used For Automotive Service & Repair — Apply controlled impact during brake, suspension, wheel, drivetrain, and general mechanical service where reduced rebound is beneficial. Industrial Maintenance & Assembly — Deliver concentrated striking force for machinery positioning, assembly, alignment, and equipment maintenance. Fabrication & Shop Work — Perform repetitive controlled striking where conventional hammer rebound can reduce accuracy and efficiency. Key Performance & Safety Features 56 oz. Head Weight: Provides substantial striking mass for demanding automotive and industrial applications. Steel Shot Core: A canister filled with steel shot inside the head creates the dead blow effect, helping reduce rebound while sustaining impact force. Shock-Absorbing Technology: Dead blow construction minimizes bounce-back and maximizes transferred striking force for controlled impacts. Polyurethane-Coated Steel Frame: GEARWRENCH specifies a steel-frame handle with polyurethane coating for durable professional use. Oil & Chemical Resistance: Exterior construction is designed to resist peeling and wear caused by exposure to oils and chemicals commonly encountered in shop environments. Precision-Balanced Handle: Ergonomic, balanced construction is designed to improve grip and comfort during extended striking tasks. What's Included (1) GEARWRENCH 56 oz. Dead Blow Hammer (GWHDB56) Pro-Tip Let the steel shot-filled head generate the dead blow effect rather than adding excessive force to each swing. Keep the striking faces clean and inspect the polyurethane exterior regularly for damage, especially when the hammer is used around sharp metal edges or harsh shop chemicals.   GEARWRENCH GWHDB56 Ratcheting Disc Brake Caliper Spreader Specifications Parameter Specification Model & Product Classification GEARWRENCH GWHDB56 | Heavy-Duty Ratcheting Disc Brake Caliper Piston Spreader Primary Application Automotive & Commercial Brake Service; Compressing Disc Brake Caliper Pistons Caliper Compatibility Works on Single, Dual, and Quad-Piston Fixed Calipers; Single and Twin-Piston Floating Calipers Working Expansion Range 1.5 in to 2.7 in (38.1 mm to 68.6 mm) Parallel Expansion Spread Drive & Ratchet Mechanism Centrally Located 360° Rotating Ratchet with Quick-Switch Reversing Lever Spreader Plate Architecture Parallel Self-Centering Dual-Plate Design (Evenly Distributes Force to Prevent Piston Cocking) Material Construction & Finish High-Strength Forged Carbon Steel Plates & Ratchet Body; Corrosion-Resistant Industrial Finish Grip & Handle Type Ergonomic Cushion-Grip Ratchet Handle for Leverage in Confined Wheel Wells Overall Dimensions (L × W × H) 10.5 in × 3.5 in × 1.25 in (26.7 cm × 8.9 cm × 3.2 cm) Total Tool Weight 0.95 lbs (0.43 kg) / 15.2 oz Automotive Brake Service & Piston Alignment Note: Engineered to eliminate uneven piston retraction when servicing modern multi-piston disc brake assemblies.
