SDMW 1205ZTN is a square 90° milling insert with 8 usable cutting edges, used mainly for heavy roughing, square shoulders and interrupted cuts. We list 2 stock-keeping variants of it from HADSTO, covering Steel, Stainless steel, Cast iron.
Milling inserts are chosen to match the cutter body — lead angle, number of teeth and the geometry designated by the manufacturer. The milling insert selection guide walks through that; this page lists what we actually hold in SDMW 1205ZTN.

Recommended cutting data
The figures below are the manufacturers' published ranges, aggregated across the 2 variants listed on this page. The typical column is the median, which is where most shops end up running. Treat the full range as the envelope, not a target — start around 60–70% of it and work up.
| Workpiece material | Cutting speed vc (m/min) | Typical vc | Feed fn (mm/rev) | Depth of cut ap (mm) | Variants with data |

To turn a cutting speed into a spindle speed for your actual diameter, use the cutting parameters calculator: n = vc × 1000 / (π × D).
