Guhring No 16 19 Piece HSCO 1.0 -10mm By 0.5mm Drill Set

The Guhring No 16 is a professional-grade 19-piece HSCO drill bit set ranging from 1.0mm to 10.0mm in 0.5mm increments, designed for demanding drilling applications in hard materials. Manufactured in Germany from high-speed cobalt steel alloy, this DIN338 standard set delivers the heat resistance and durability required for industrial metalworking.

HSCO (High-Speed Cobalt) construction provides superior performance when drilling steel, high-alloyed steel, and various cast iron materials including grey cast iron, spheroidal graphite iron, and malleable cast iron. The cobalt alloy composition offers increased strength and heat resistance compared to standard HSS bits, making this set ideal for high-performance applications where conventional drill bits would quickly lose their edge.

The steam-tempered surface treatment enhances wear resistance, whilst the 118-degree point angle ensures efficient cutting action. Each bit features a right-hand cutting direction and straight shank design, making them compatible with both hand-held drills and machine operations. With a machining depth of approximately 5 times the diameter, these bits offer greater versatility than stub-length alternatives for deeper hole drilling.

This set is widely used across construction, automotive, and aerospace sectors where precision drilling of harder materials is essential. The h8 tolerance ensures consistent hole sizing for professional applications. Supplied in a protective case, the set provides comprehensive coverage for contractors and fabricators working with ferrous metals, with limited suitability for stainless steel, aluminium, and other non-ferrous materials.
