Cirkelsågen

cirkelsågen, or circular saw, is a handheld power tool that uses a blade with a continuously rotating abrasive cutting disc. It is commonly used in carpentry, woodworking, and construction for cutting wood, plastics, metals, and other materials. The blade is usually 7 to 10 inches in diameter, and the saw is powered by a gasoline engine or an electric motor from a battery or AC source.

The first commercial circular saw was introduced in the 1850s and initially designed for hardwoods. By the late 1800s, the tool was adapted for use in sheet‑metal work, leading to the development of the pneumatic circular saw. Modern versions include variable‑speed drives, bevel‑angle adjustments, and ergonomic handles with dust collection ports.

cirkelsågen come in two main categories: handheld models for field work and stationary or table saws used in workshops. Handheld saws are ideal for precision cuts or rough work on site, while table saws provide a stable work surface and a more controlled environment. Many models feature depth gauges, rip fences, and adjustable bevel angles to increase accuracy.

Safety guidelines for operating a circular saw include wearing eye and hearing protection, ensuring the blade is properly installed and guarded, and marking cut lines accurately before starting. The saw should be turned off and unplugged when changing blades or cleaning.

Today, brands such as Makita, Bosch, DeWalt, and Milwaukee produce a wide range of circular saws. Their variations in power, weight, and special features allow professionals and hobbyists alike to select a model suited to particular tasks.
