DeWalt 10 Piece Elite HSS-E Cobalt Drill Bit Set

The DeWalt Extreme 10 Piece HSS-E Cobalt Drill Bit Set is a professional-grade metal drilling solution, offering a comprehensive size range from 1mm to 10mm for tackling high alloy steels and hard metals on site. Constructed with cobalt-enriched HSS-E steel, these drill bits are engineered to cut through demanding materials including stainless steel, cast iron, bronze, and titanium — materials that quickly overwhelm standard HSS bits. The set handles metals with a tensile strength up to 1100N/mm², making it a reliable choice for contractors and metalworkers working with harder alloys. The no-walk tip design prevents the bit from skating across curved or smooth metal surfaces, improving accuracy from the first contact. A reinforced central core increases fracture stability during freehand use, while the three-sided non-slip shank ensures a secure, spin-proof grip in the drill chuck — a practical detail that counts when working at pace on a busy job site. Performance is further enhanced by optimised tip and flute geometry, delivering up to four times the penetration speed compared to standard HSS drill bits. Suitable for both portable and stationary drilling applications, this set covers the most common drilling diameters in a single compact case.
