This page covers every RDHW 12T3 insert we can supply — 2 variants across Achteck, published for 钢, 不锈钢, 铸铁, 耐热合金. The round geometry gives it many cutting edges and makes it suitable for the strongest edge available — roughing, hard skins, long reach.
铣削刀片 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 RDHW 12T3.

Carbide grades available
2 variants of RDHW 12T3 are stocked in these grades: AP251K, AP351U.
Across this range the grades specified most often are AP251K, AP351U. 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.
槽型 geometries
断屑槽 stocked for RDHW 12T3: HR2.
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.
