Twist Drills

RUKO Shop UK offer a variety of high-performance Jobber Twist Drills in different materials and sizes, to suit all your needs:

High Speed Steel (HSS) - enabling drilling at higher speeds and through harder materials. Ideal for all-round metal drilling.

Cobalt HSS - increases the material's hardness above ordinary HSS.

Blacksmith (HSS Black) - with a reduced shank making it more resistant to fracture and suitable for robust drilling units.

TIN Coated - Titanium is a corrosion-resistant metal that is utilized as a coating on HSS drill bits to give them extremely high surface hardness levels in the form of titanium nitride, or TiN. Titanium-coated drill bits can drill through difficult materials and last up to six times longer than ordinary HSS bits.
