The Starrett KDC05021 is a professional 7-piece electricians hole saw set featuring deep cut bi-metal construction with extra cobalt HSS teeth for enhanced durability. This comprehensive kit combines the aggressive tooth form from Starrett's dual pitch design with new heat and wear-resistant tooth material, making it ideal for electricians working with conduit, cable routing and fixture installation across multiple materials.
The deep cut design offers a 51mm cutting depth, providing a 10mm increase over standard hole saws and delivering superior performance when cutting through pipes and tubes. The extended depth allows you to cut through both sides of a tube in a single operation, particularly valuable when working with conduit or pipework with wall thickness greater than 3mm. The aggressive 4-6 teeth per inch configuration ensures rapid material penetration and excellent kerf clearance across metals, wood, plastic and plasterboard.
This versatile set suits a wide range of electrical installation work, from routing cables through joists and studs to creating access points for back boxes and conduit. The bi-metal construction with HSS teeth delivers exceptional heat resistance during prolonged use, whilst the reduced vibration and smooth cutting action minimise user fatigue during repetitive drilling tasks on site.
