Replacement solid carbide inserts for Schmidt insert heads — indexable straight knives in S2 and S4 styles, sold ten to a package, alongside profiled inserts ground to match dedicated bodies.
S2 knives run from 1/4" up to 80mm cutting lengths and S4 squares from 12mm to 18mm; all take a 4.0mm screw hole except the 14×14×2.0mm INKS414, which uses a 6.5mm hole with chamfer. Matching replacement screws and Torx wrenches are stocked — confirm the head’s pocket size and insert number before ordering.
