Grinders are handheld power tools designed to perform various tasks, including removal, cutting, grinding, or polishing different materials in construction, metalworking, woodworking, and other industries. A grinder consists of a motor-driven head that holds a disc or wheel (various types, depending on the application) at a right angle to the motor's shaft. The motor can vary in power from smaller, handheld models to larger, more powerful ones.
Grinders come in various sizes, from portable handheld devices to larger ones suitable for heavy-duty tasks in multiple settings. These hand-operated tools either come in designs that get power from electricity (corded grinders) or batteries (cordless). Corded grinders provide consistent power for the long run, while battery-powered grinders offer portability but have limited battery life. Enrgtech offers advanced collections of angle grinders from leading brands, including Bosch, DeWalt, Makita, and Milwaukee angle grinders.
Popular Types of Grinders:
Grinders come in various types based on their design, mounting type, and applications. Some common grinder types include:
- Angle Grinders – Also called a disc grinder or side grinder, an angle grinder is a power tool with a motor and a spinning abrasive disc or wheel. It is commonly used for cutting, grinding, polishing, and removing excess material from surfaces like metal, concrete, and stone. Angle grinders come in various sizes and power ratings, accommodating different abrasive discs or wheels for specific tasks. A Corded angle grinder and a cordless angle grinder are examples of angle grinders.
- Bench Grinders – A bench grinder is a stationary power tool mounted on a workbench or a dedicated stand. It comprises two rotating abrasive wheels for coarse grinding and finer sharpening or polishing. Bench grinders are also used for sharpening tools like chisels, drill bits, and knives, facilitating shaping and deburring metal or other materials.
- Air Grinders – These handheld grinders use compressed air from an air compressor to drive a spinning abrasive wheel or attachment. Using compressed air makes an air power grinder suitable for environments where electric power sources might be impractical or unsafe. They are commonly used in various industrial and automotive applications for cutting, grinding, polishing, and deburring tasks.
- Die Grinders – Die grinders are handheld versatile tools for grinding, polishing, sanding, honing, or machining various materials. They are popular in metalworking, woodworking, and automotive applications. A die grinder is known for its versatility and precision, making it indispensable for tasks that require intricate detailing or material removal in tight spaces.
