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 2 (W.-Nr. 3.7035). The numbers are the published S01 Titanium (commercially pure) sub-group starting band; the designations are on the cross-reference page.
| Item | Value |

| ISO 513 group | S Superalloys and titanium |
| Sub-group | S01 Titanium (commercially pure) |
| Sub-group hardness / condition | ~200 HB · 30 HRC |
| Category | Titanium (commercially pure) |
| EN / Werkstoffnummer | Ti Grade 2 · 3.7035 |
Hardness is the range published for the whole S01 Titanium (commercially pure) sub-group on our material guide; the delivery condition of your Titanium Grade 2 may sit anywhere inside it or outside it.
| Condition | Vc m/min | Vc sfm | Feed mm/rev | Feed ipr |
|---|---|---|---|---|
| S01 Titanium (commercially pure), ~200 HB · 30 HRC | 40–90 | 130–295 | 0.10–0.25 | .004–.010 |
Sub-group starting values for carbide inserts, from S01 Titanium (commercially pure). They describe the whole sub-group and are not tuned to Titanium Grade 2. 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, high positive rake, polished flute; keep the tool moving | Sharp fine-grain carbide, uncoated or thin PVD | High-pressure coolant | Heat at the edge: keen edge and coolant |
| Finishing | Sharp, high positive rake, polished flute | Uncoated or thin PVD fine-grain carbide | High-pressure coolant | Galling and built-up edge: raise speed into the band |
| Interrupted cut | Sharp positive edge; never dwell | Fine-grain carbide, uncoated or thin PVD | High-pressure coolant | Long gummy chips: keep feed up for clearable chips |
| Low rigidity / thin wall | Sharp positive geometry so the chip thins out | Fine-grain carbide, uncoated or thin PVD | High-pressure coolant | Change edges early: a worn edge generates heat |
Setup rows are the selection table of the S01 Titanium (commercially pure) guide. They carry no speeds, so they do not change the starting band above.
Sharp, fine-grain carbide, uncoated or thin PVD. A keen edge matters more than coating.
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 Grade 2, Werkstoffnummer 3.7035, US UNS R50400 (ASTM B348 Gr. 2), JIS TP340 (nearest). The full table, with the nearest-match flags, is on the Titanium Grade 2 / 3.7035 cross-reference page.
Softer than Ti-6Al-4V but every titanium rule already applies: low speed, constant feed, copious coolant, never let the tool dwell or rub.

The published starting band for the S01 Titanium (commercially pure) sub-group is 40–90 m/min (130–295 sfm) at 0.10–0.25 mm/rev (.004–.010 ipr). It is a starting band for the whole sub-group, not a value tuned to Titanium Grade 2, so confirm on a sample part and adjust for condition, tool and rigidity.
Sharp, fine-grain carbide, uncoated or thin PVD. A keen edge matters more than coating. 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.
