For the machinists and CNC operators out there – here's a 10-pack of OKE brand carbide inserts, specifically the MGMN300-M style with OP1215 geometry. These are cut-off (parting) inserts, designed for slicing through bar stock, particularly tough materials like stainless steel. They come brand new in their factory box, ready to load into your tool holder. Carbide means they stay sharp and handle high heat, which is crucial when parting off. Using fresh, sharp inserts makes a huge difference in finish quality, chip control, and tool life. Having a 10-pack on hand means you can run your machine longer without stopping to hunt for inserts. Just match the insert shape and hole pattern to your existing parting tool holder. Made in China, but OKE is a known name in the value insert market. A solid, cost-effective supply for your shop. Keep your parting operations smooth and predictable.
