WIDIA H101Z07938 TOP Drill Deep-Hole Drill - 0.3125" Cutting Diameter, 132° Cutting Angle, Right Hand Cut, 15XD, 0.315" Shank, Carbide with TiAlN Coating - Perfect for Precision Metalworking & Deep Hole Drilling in Aerospace, Automotive & Industrial Applications

Solid carbide deep-hole drills outperform gun drills and HSS deep-hole drills in deep-hole applications up to 30 x D by increasing metal removal rates by 3–4 times. Increased MRR equals bottom-line savings to customers in throughput, machine time, and personnel hours. The TDD1*Z* Series in the WU20PD grade offers secure and consistent performance, excellent hole quality, and reduced cycle times. The standard lines are available from 3 to 13mm and lengths of 15, 20, 25, and 30 x D. It eliminates the traditional HSS or gun drilling without pecking, at up to 100% increased penetration rates.
