Magnum 3/4 Inch Cobalt Lathe Parting and Cut Off Blade (CCOB34)

Parting off tough steel on a manual lathe demands a blade that resists extreme heat and edge wear. This 3/4-inch cut-off blade handles aggressive cuts without losing its temper. The high-cobalt alloy construction provides excellent red hardness, making it a reliable choice for separating heavy stock or grooving tough materials like stainless steel.
