This page covers every LNGX 120508ER insert we can supply — 2 variants across HADSTO, published for Steel, Stainless steel, Cast iron. The rectangular 90° geometry gives it 2 cutting edges and makes it suitable for grooving, parting and shoulder work.
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 LNGX 120508ER.

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).
Carbide grades available
2 variants of LNGX 120508ER are stocked in these grades: HS5120, HS5130.
Across this range the grades specified most often are HS5120, HS5130. Within one brand's range, a higher middle digit usually means a tougher grade — better on interrupted cuts, slightly less wear resistant. See carbide grades explained for how to read the names.
Chipbreaker geometries
Chipbreakers stocked for LNGX 120508ER: M.
For milling, the geometry code marks the intended duty — sharper for light cuts and better finish, stronger for scale and interruption. Milling insert selection guide.
