## Description

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-R drill bits. Suitable for both portable and stationary drilling applications, this set covers the most common drilling diameters in a single compact case. Features and Benefits: • HSS-E cobalt construction for drilling hard metals including stainless steel, cast iron, bronze, and titanium • No-walk tip prevents skating on curved or smooth metal surfaces for accurate hole placement • Three-sided non-slip shank provides secure, spin-proof grip in the drill chuck • Reinforced central core improves fracture stability during freehand use (4.8mm and above) • Optimised tip and flute geometry delivers up to 4x faster penetration vs HSS-R metal drill bits • Suitable for portable and stationary drilling of metals up to 1100N/mm² tensile strength Contents: HSS-E Cobalt Metal Drill Bits: 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm
