25 Piece HSS Co Drill Bit Set

The Sealey 25 Piece HSS-Co Drill Bit Set is a comprehensive drilling solution designed for tradespeople working with hard and challenging materials. Manufactured from fully ground high-speed steel with 5% cobalt content, this drill bit set delivers enhanced durability and heat resistance when drilling through extra hard materials including stainless steel, hardened steel and cast iron. Each drill bit features a 135° split point tip that enables quick and precise penetration of the workpiece, significantly reducing the need for centre punching before drilling. This design characteristic improves drilling accuracy whilst saving valuable time on site. The bits can be resharpened multiple times without compromising their cutting performance, extending the working life of the set and providing excellent long-term value. The set comprises 25 drill bits ranging from 1mm to 13mm diameter in convenient 0.5mm increments, covering the most commonly required sizes for general workshop and site applications. All bits are supplied in a durable metal storage case that keeps the set organised and protected between jobs, making it ideal for professional contractors, engineers and maintenance technicians who require reliable drilling performance across a wide range of materials.
