The Sealey 99 Piece HSS Cobalt Fully Ground Drill Bit Set is a comprehensive drilling solution engineered for demanding metalwork applications including high carbon steel and stainless steel. This professional-grade drill bit set features HSS cobalt construction with 5% cobalt content, significantly extending the operational life of each bit compared to standard HSS tooling. The fully ground design ensures precision and consistency across all diameters, whilst the 135° split point geometry delivers self-centring capability for accurate hole placement and easier penetration without walking or wandering on start-up. The set provides exceptional versatility with 99 pieces spanning commonly used diameters from 1.5mm to 10mm, with multiple bits supplied in frequently used sizes to ensure replacements are always available.
