6.35 x 12 x 1.5mm Reversible Carbide Knives, Box of 10

S2-style solid carbide indexable insert knife, 6.35 x 12 x 1.5mm (1/4 in. cutting width), supplied in boxes of 10 with a 4.0mm mounting hole. Turnable straight knives index to a fresh edge as they dull — no regrinding. This is the smallest of the S2 straight-knife series and is the replacement insert used in the IG625 adjustable groover; it also fits any Schmidt insert head or backer that takes the 12mm S2 profile.
