Starrett CSC20 Holesaw 20mm Bi-Metal

The Armeg CSC20 Carbide Sheet Cutter is a professional 20mm carbide-tipped hole cutter designed for fast, precise cutting in stainless steel, mild steel, and other tough sheet metals. Engineered for electricians, installers, and metal fabrication professionals, it delivers high-performance cutting in demanding trade environments.

Fitted with tungsten carbide cutting teeth, the CSC20 provides excellent durability, heat resistance, and long service life, allowing it to outperform standard bi-metal hole saws when working with hard metals. This ensures cleaner, faster cuts with reduced wear even under repetitive use.

Its solid one-piece construction enhances strength and stability, reducing vibration and improving accuracy during operation. This rigid design helps maintain consistent cutting performance when working on electrical enclosures, trunking, and steel panels.

The cutter is optimised for shallow-depth metal cutting, making it ideal for sheet steel applications commonly found in electrical installation, HVAC systems, and light fabrication work. An integrated design also allows for efficient slug removal, improving productivity on site.
