Sealey 3 Piece M2 HSS Step Drill Bit Set

The Sealey 3 Piece M2 HSS Step Drill Bit Set is a professional drill bit solution designed for precision hole drilling across multiple diameters. Constructed from high-speed steel M2, this versatile set allows tradespeople to drill 18 different hole sizes using just three bits, making it an efficient choice for electricians, plumbers and metalworkers who need to work with various gauge holes on site. Each step drill features double straight flutes that provide efficient swarf clearance, ensuring clog-free operation when drilling through sheet metal, plastic and other thin materials. The graduated step design eliminates the need for multiple conventional drill bits, saving time on repetitive tasks such as cable entry holes, conduit preparation and panel work. The three bits cover comprehensive size ranges: Size 1 spans 4-12mm in 1mm increments, Size 2 covers 4-22mm in 2mm increments, and Size 3 extends from 4-30mm, also in 2mm increments. The set is supplied in a durable flip-up metal case that keeps the bits organised and protected between jobs.
