Industrial SM-190 Carbide Insert Shims

Industrial SM-190 Carbide Insert Shims are precision-ground tungsten carbide spacers that sit between the cutting insert and the tool holder seat to provide a hardened support surface, improving insert stability and protecting the holder in indexable cutting systems. Designed for use in CNC lathes, turning centers, milling machines, boring bars, and other precision metalworking equipment employing indexable inserts, these shims are commonly installed to maintain insert positioning and extend tool life during high-speed machining. Each pack includes 5 pieces and the shims are compatible with indexable turning and milling tool holders; they are manufactured as generic / OEM-compatible, model SM-190, and constructed as precision-ground carbide shims with high wear resistance and heat tolerance. The surface finishes on the contact faces are precision ground to ensure consistent seating, reducing insert seat wear and aiding in setup accuracy across CNC turning and milling operations. Typical applications include turning, milling, boring, and threading tools within CNC workflows where maintaining exact insert positioning is critical; common replacements from Kennametal, Sandvik, and Seco Tools are available as equivalents.
