[QUOTE="shortgrass, post: 1179321, member: 24284"] Until it doesn't work as it should or breaks? Impossible to answer. Reamer made of what material, carbide or high speed steel (probably carbide), feed rate per revolution, how many RPM, how many 'pecks', was a roughing reamer used, what's the barrel made of, 4140/4150 or stainless, the consistancy of the barrel steel, what coolant used, was it mixed per the coolant manufactures recommendations, how is the coolant supplied to the tool, muzzle flush or externally, is the machine program capable of "constant SFM" as most reamers taper from smaller at the shoulder to larger at the head? This is not taking into consideration the ridgidity of the machine or the tool holder or the skill of the operator. Too many variables to give any kind of educated answer...... I have HS reamers, used on my manual lathe with a muzzle flush, with 15+ chambers on them and still cutting 'strong'. [/QUOTE]
