Bosch Tungsten Carbide Tipped Annular Cutter with Universal Shank (Cut Depth 35 mm)

An annular cutter is a specialized cutting tool used primarily in metalworking applications to create holes in various metals with precision and efficiency. Unlike traditional twist drills, annular cutters feature a hollow cylindrical design with multiple cutting edges along the circumference. This design allows them to remove material in a more efficient manner, producing clean, accurate holes with minimal effort.

The key components of an annular cutter include the body, which is typically made of high-speed steel or cobalt alloy for durability and heat resistance, and the cutting edges, which are strategically placed around the perimeter of the cutter. These cutting edges are designed to penetrate the metal surface and remove material in a circular fashion, leaving behind a core or slug-shaped piece of metal.

Annular cutters are often used in metal fabrication, construction, and manufacturing industries for tasks such as drilling holes for bolts, fasteners, and pipe fittings. They are capable of cutting through various metals including steel, stainless steel, aluminum, and cast iron, making them versatile tools in metalworking applications.

One of the main advantages of using annular cutters is their efficiency and speed compared to traditional drilling methods. Because they only remove material from the circumference of the hole, they require less power and produce less heat, resulting in faster cutting speeds and extended tool life.
