Starting cutting speed in m/min and sfm, feed in mm/rev and ipr, the carbide grade class and the setup by operation for Titanium Grade 9 (Ti-3Al-2.5V). The numbers are the published S10 Titanium alloys (Ti-6Al-4V) sub-group starting band; the designations are on the cross-reference page.

Hardness is the range published for the whole S10 Titanium alloys (Ti-6Al-4V) sub-group on our material guide; the delivery condition of your Titanium Grade 9 may sit anywhere inside it or outside it.
| Condition | Vc m/min | Vc sfm | Feed mm/rev | Feed ipr |
|---|---|---|---|---|
| S10 Titanium alloys (Ti-6Al-4V), 320–380 HB | 30–60 | 100–195 | 0.10–0.20 | .004–.008 |
Sub-group starting values for carbide inserts, from S10 Titanium alloys (Ti-6Al-4V). They describe the whole sub-group and are not tuned to Titanium Grade 9. sfm and ipr are converted from the metric values (1 m/min = 3.281 sfm, 25.4 mm = 1 in). The published band is per sub-group, not per operation; the table below gives the setup by operation. Convert Vc to spindle speed with the speeds & feeds calculator, and see the speeds & feeds guide for the ISO S group range.
| Operation | Geometry | Coating family | Coolant | First check |
|---|---|---|---|---|
| Roughing | Sharp positive rake, polished flute; climb-mill, keep the tool moving | Fine-grain carbide, uncoated or thin PVD (TiAlN) | Generous high-pressure coolant | Heat-driven flank and crater wear: hold a modest Vc |
| Finishing | Sharp positive rake, polished flute, keen edge | Fine-grain carbide, uncoated or thin PVD (TiAlN) | Generous high-pressure coolant | Built-up edge: raise Vc into the band, coolant at the edge |
| Interrupted cut | Sharp positive edge; climb-mill so the chip exits thin | Fine-grain carbide, thin PVD | Generous high-pressure coolant | Chip welding and re-cut: keep the feed steady |
| Low rigidity / thin wall | Keen edge, positive rake; never let the tool dwell | Fine-grain carbide, thin PVD | Generous high-pressure coolant | Change inserts early: a worn edge risks glowing chips |
Setup rows are the selection table of the S10 Titanium alloys (Ti-6Al-4V) guide. They carry no speeds, so they do not change the starting band above.
Same sub-group, same starting band: Ti-6Al-4V
Sharp, fine-grain carbide, uncoated or thin PVD (TiAlN). A heavy coated edge traps heat in titanium, so keep the edge keen.
The P, M, K, N, S or H number inside a grade range describes what the grade is built for, not the workpiece sub-group number, and the two scales must not be matched to each other. We name no single grade here: none of our published sources ties a named grade to this alloy. Pick by ISO class, then compare what the makers publish on the ISO S grade list and in the grade chart.
EN Ti-3Al-2.5V (Grade 9), Werkstoffnummer 3.7195, US UNS R56320. The full table, with the nearest-match flags, is on the Titanium Grade 9 / 3.7195 cross-reference page.
Between CP titanium and Ti-6Al-4V in strength and machinability: same titanium rules, slightly friendlier data than Grade 5.

The published starting band for the S10 Titanium alloys (Ti-6Al-4V) sub-group is 30–60 m/min (100–195 sfm) at 0.10–0.20 mm/rev (.004–.008 ipr). It is a starting band for the whole sub-group, not a value tuned to Titanium Grade 9, so confirm on a sample part and adjust for condition, tool and rigidity.
Sharp, fine-grain carbide, uncoated or thin PVD (TiAlN). A heavy coated edge traps heat in titanium, so keep the edge keen. Pick the grade by ISO class rather than by brand name, then confirm the exact grade for your condition. We name no single grade here because none of our published sources ties a named grade to this alloy.
