18 x 18 x 1.95mm Reversible Carbide Knives, Box of 10

The INKS418 provides a box of 10 solid carbide 18 x 18 x 1.95mm reversible square knife inserts for Schmidt indexable insert heads designed for this specific geometry. At 18 x 18mm and 1.95mm thick, the INKS418 bridges the size gap between the 15mm (INKS415) and 20mm (INKS220) inserts — a size specification that is head-model-specific and non-interchangeable with adjacent sizes. Square 18 x 18mm inserts provide four indexable positions, each presenting a fresh cutting edge, making the insert cost per cutting-edge-use very efficient in high-frequency production operations. The 1.95mm thickness is specific to the INKS418 seat geometry and differs from the 1.5mm and 2.0mm/2.5mm sizes in adjacent INKS series items. Confirm the insert head model specifies INKS418 geometry before ordering — substituting a different thickness insert in the seat risks incorrect seating depth and compromised cutting performance. Sold in boxes of 10.
