Guhring No 16 25 Piece HSCO 1.0 -13mm By 0.5mm Drill Set

The Guhring No 16 25 Piece HSCO Drill Set is a professional-grade drill bit set designed for precision drilling in hard materials. Manufactured in Germany from high-performance cobalt steel alloy (HSCO), this comprehensive set provides exceptional strength and heat resistance for demanding applications.

This DIN338 standard set features 25 straight shank twist drills ranging from 1.0mm to 13mm in 0.5mm increments, offering excellent versatility for professional tradespeople. The steam-tempered surface treatment enhances durability and wear resistance, whilst the 118° point angle ensures accurate starting and efficient material removal. The extended flute length design allows for drilling depths up to approximately 5 times the drill diameter, making these bits particularly suitable for deeper hole drilling compared to stub length alternatives.

The cobalt steel alloy construction makes this set ideal for use in construction, automotive, and aerospace industries where drilling harder materials is routine. These drills perform optimally in steel, high-alloyed steel, and various cast iron materials including grey, spheroidal graphite, and malleable variants. They're suitable for both hand-held and machine-operated drilling applications, providing professional contractors with reliable performance across diverse metalworking tasks.

Features and Benefits:
• German-engineered HSCO construction for superior heat resistance and extended tool life
• Comprehensive 0.5mm increment sizing provides precise hole diameter options
• Steam-tempered surface finish reduces friction and improves wear characteristics
• h8 tolerance rating ensures consistent accuracy for professional applications
• Supplied in protective case for organised storage and transportation
