The Draper 19 Piece HSS TiN Drill Bit Set delivers professional-grade drilling performance across a wide range of materials. This comprehensive HSS drill bit set features titanium nitride coating for enhanced durability and extended service life, making it ideal for tradespeople and contractors who demand reliable tools for everyday use. Each bit is fully ground with a 135° split point that provides precise centring to prevent drill wander, ensuring accurate hole placement from the first contact. The titanium nitride coating not only extends bit life but also reduces friction during operation. For optimal performance and longevity, these bits work best when used with a suitable cooling agent, particularly when drilling harder materials. The set covers a comprehensive size range from 1.0mm to 10.0mm in 0.5mm increments, providing versatility for various drilling applications. Suitable for drilling steel, non-ferrous metals, wood and hard plastic, these bits are compatible with standard 10mm or 13mm drill chucks found on most power drills. The complete set is supplied in a protective plastic case for organised storage and easy transportation between job sites.
