Hammers are fundamental hand or power tools designed to deliver impact force for driving, shaping, or breaking materials. Modern hammers integrate advanced materials and ergonomic designs to enhance precision, safety, and efficiency across industries such as construction, manufacturing, and maintenance.
| Type | Functional Features | Application Examples |
|---|---|---|
| Claw Hammer | Curved claw for nail removal, balanced striking face | Carpentry, demolition |
| Ball Peen Hammer | Round peen for metal shaping, hardened striking surface | Metalworking, riveting |
| Rubber Mallet | Non-marring elastic head, vibration absorption | Furniture assembly, automotive |
| Electric Hammer | Motor-driven impact mechanism, adjustable force | Concrete drilling, heavy-duty construction |
| Impact Hammer | High-torque rotational force, socket compatibility | Mechanical repair, bolt tightening |
Typical hammers consist of: - Head: Forged steel or composite materials with hardened striking surfaces - Handle: Fiberglass, wood, or polymer with anti-vibration coatings - Connection System: Wedge-lock or integral molding to prevent head detachment - Ergonomic Elements: Textured grips, shock-absorbing cores
| Parameter | Description | Importance |
|---|---|---|
| Head Weight | 0.2-10 kg range | Determines impact force and user fatigue |
| Material Hardness | 50-60 HRC for steel heads | Affects durability and spark resistance |
| Handle Length | 200-500 mm | Influences torque and control precision |
| Impact Energy | 1-50 J (power tools) | Dictates material penetration capability |
| Vibration Damping | 0-20 m/s | Reduces repetitive strain injuries |
| Manufacturer | Representative Product | Key Innovation |
