The Starrett Fast Cut Bi-Metal Holesaw (121mm) is designed for efficient, smooth cutting across a range of materials. It features an improved 5.5 TPI tooth form and cobalt-infused HSS teeth for enhanced heat resistance, wear resistance, and durability. The blade is optimized for cutting stainless steel and mild steel sheets, and it can also cut through tubes with wall thickness up to 3mm (1/8 inch). With a cutting depth of 41mm (1.62 inches) and increased gullet volume for better material clearance and penetration, this holesaw is suitable for both DIY and professional projects. It is intended for use with standard hole saw arbors and drill chucks and requires appropriate speed settings for metal cutting.
