VT machining offers CNC Drilling for Ti-6Al-4V Titanium (UNS R56400 / R56401 (ELI) / TC4), typically supplied annealed or STA. Same alloy as Grade 5; ELI version (Gr23) is specified for implants.
CNC Drilling Notes for Ti-6Al-4V Titanium
Drilling Ti-6Al-4V Titanium uses through-coolant carbide drills and peck cycles, because the chip tends to weld and the hole wall work-hardens if the drill dwells.
For estimating, a 100 × 100 × 10 mm block of Ti-6Al-4V Titanium weighs about 0.44 kg.
