Using this center drill creates a precise starting hole that centers the workpiece, improving clamping stability and reducing runout in turning and milling operations. The 118°/60° geometry yields clean entry and a true center, while the bright finish minimizes built-up edge and sticking. The double-ended design lowers downtime by providing a spare drilling end, and the HSS-E construction offers durability across multiple materials. Ideal for workshops that require reliable center holes in shafts and consistent alignment in both CNC and manual setups.
