C20-160-8D
ø16mm 8D JCD Replaceable-Tip Drill Shank

The 8D shank brings replaceable-tip economics to deep-hole applications where conventional solid carbide tools are prohibitively expensive. Designed for oil passage drillings, structural steel, and heavy engineering components. Requires internal coolant at ≥ 20 bar for reliable chip flush at full depth.
