What Is a Jack Hammer?
A jack hammer, also known as an electric hammer, concrete hammer, or concrete breaker, is an electric tool primarily used for grinding concrete and stone, removing paint, tile floors, rust, glue, and for carving wood. It operates using ultra-high-speed micro-vibrations to minimize dust and prevent damage to the substrate.
Uses of Jack Hammers
Jack hammers are versatile tools used in various applications, such as:
- Peeling and removing paint, tiles, rust, and adhesives from surfaces without damaging the underlying material.
- Working on exterior walls of buildings using specialized replacement blades.
- Engraving materials like metal, glass, wood, and plastic, with a focus on reducing scatter and ensuring precise work.
Features of Jack Hammers
- Hammer drills combine rotation and impact to drill holes in concrete and other materials, while vibration drills use rotation and vibration for more delicate drilling tasks.
- Jack hammers come with different power sources: rechargeable, AC-powered, and dust-collecting models. The rechargeable type offers portability, while models with dust collectors include a dust bag for cleaner operation.
- Key specifications such as drilling size, availability of drill mode, shank shape, blow force (J), and no-load blow rate (min-1) are important factors to consider. The blowing force indicates the impact energy and the no-load blow rate shows the number of impacts per minute under no load. Some models feature a selectable hitting mode for blow-only operation.
- The weight of the device, cord presence, cord length, and the ability to change blades are also considerations based on the specific application and usage requirements.
