The Sealey 3 Piece Spiral Fluted M2 HSS Step Drill Set is a versatile drilling solution designed for creating multiple hole sizes in sheet metal, plastic, and other thin materials. This professional-grade set features high-speed steel M2 construction for durability and heat resistance, making it suitable for electricians, HVAC engineers, and metalworkers who regularly work with electrical enclosures, ducting, and fabrication projects. The double spiral flute design ensures efficient swarf clearance during operation, allowing for clog-free, precision drilling without the need to frequently withdraw the bit. With three step drills covering 18 different hole sizes, this set eliminates the need to carry multiple conventional drill bits, saving time and storage space on site. The stepped design also provides excellent control when enlarging existing holes or creating clean pilot holes. Each drill offers a comprehensive range of diameters, from 4mm up to 30mm on the largest bit, making this set ideal for everything from small cable gland installations to larger penetrations for conduit and pipework. The bits are supplied in a protective storage case to keep them organised and protected between jobs.
