Highly Polished Surfaces • Reduction of friction in the chip flute and on the lands, resulting in superior chip evacuation. • Shorter drilling time through omission of reversing cycles. WU20PD™ Grade • Advanced TiAlN multilayer PVD coating for steel and cast iron. • Ultra fine-grain carbide ensures process reliability at high feed rates. Customisation • Intermediate sizes, even up to 16mm diameter, available as semi-standards. • Length variations, including longer versions up to 550mm, available as custom solutions. • For drilling non-ferrous and uncoated materials, sharp versions are recommended and available as custom solutions. • Excellent surface finish and concentricity. widia.com T105
