VT machining offers CNC Tapping for Grade 12 Titanium (UNS R53400 / Ti-0.3Mo-0.8Ni), typically supplied annealed. Cheaper Pd-free alternative to Gr7 with better high-temperature strength than Gr2.
CNC Tapping Notes for Grade 12 Titanium
Grade 12 Titanium is tapped with cut taps (spiral-point for through holes) and controlled rigid-tapping speed; thread milling is used where tap breakage would be costly.
For estimating, a 100 × 100 × 10 mm block of Grade 12 Titanium weighs about 0.45 kg.

Does CNC Tapping Grade 12 Titanium require dedicated tooling?
Most Grade 12 Titanium machining work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
How clean are the edges produced by CNC Tapping on Grade 12 Titanium?
Machined Grade 12 Titanium edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.
What is the typical lead time and minimum order for CNC Tapping Grade 12 Titanium?
CNC Tapping prototypes for Grade 12 Titanium can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.
Why is Grade 12 Titanium a good choice for CNC Tapping?
Grade 12 Titanium is high strength-to-weight, biocompatible and corrosion resistant, which makes it well suited to CNC Tapping. We tune the process to the alloy so the finished Grade 12 Titanium machining part meets your dimensional and functional requirements.
