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

The INKS250 provides a box of 10 solid carbide 50 x 12 x 1.5mm reversible knife inserts for Schmidt indexable insert heads. At 50mm, the INKS250 is the longest knife in the standard INKS reversible knife series, suited to wide-seat insert heads for surfacing, jointing passes, and material removal operations where a longer cutting edge covers the full width of the cut in fewer passes. The 50 x 12 x 1.5mm geometry is specific to insert heads designed for this knife size — seats that accept INKS250 knives have 50mm insert seat dimensions. Two-sided reversibility doubles the effective cutting life per knife. Production shops running wide surfacing operations on insert heads benefit from stocking INKS250 boxes to keep insert changes quick: a fresh knife is seated and clamped in seconds versus the hours required to regrind or replace a conventional solid-carbide cutter. Confirm head model compatibility before ordering.
