Not all tooling manufacturers publish their Machinability Rating the same way. While the underlying physics doesn't change, the recommended ranges, safety margins, and application guidance vary considerably across Korloy, Tungaloy, and TaeguTec. Understanding these differences helps you make better tooling decisions.
Takes a material-group-first approach with Ionbond-coated grades as default. Their application guides provide conservative starting values with wide adjustment bands. CoroPlus digital integration offers real-time Machinability Rating optimization via ToolGuide.
Known for aggressive starting parameters — particularly in steel and cast iron. NOVO digital platform auto-adjusts Machinability Rating based on tool path engagement. Often the go-to reference for high-feed applications.
Pioneers of multi-directional Machinability Rating — their IQ series inserts thrive in turning profiles where engagement angle shifts continuously. Application-specific grades for ISO P/M/K with narrow, optimized Machinability Rating windows.
Key takeaway: Always default to your specific tool supplier's Machinability Rating charts. The differences between Korloy, Tungaloy, and TaeguTec reflect different coating chemistries (Ionbond vs. in-house) and carbide substrate formulations. A Korloy parameter won't necessarily translate to a Tungaloy equivalent — even at the same ISO grade designation.
Machinability rating is a relative index comparing how easily a material can be machined. The baseline (100%) is 160 Brinell B1112 free-cutting steel. A rating of 50% means the material machines half as fast with half the tool life; 200% means twice as fast with double the tool life.
304 stainless work-hardens rapidly -- the cutting action itself hardens the material ahead of the tool. The high nickel and chromium content also causes the chip to adhere to the tool (built-up edge), which degrades surface finish and accelerates tool wear. Low thermal conductivity (1/3 of carbon steel) concentrates heat at the tool tip instead of carrying it away with the chip.
Sulphur (0.15-0.35%) and/or lead (0.15-0.35%) additions form inclusions that act as internal chip breakers and lubricants. 12L14 (leaded) and 1215 (non-leaded, high-sulphur) machine beautifully. The trade-offs: leaded steels cannot be welded (hot cracking), and high-sulphur steels have lower transverse ductility and impact strength.
Traditional machinability rating was based on the cutting speed that gives 60-minute tool life with HSS tools. Modern machinability ratings consider multiple factors: tool life, surface finish, chip formation, power consumption, and dimensional stability. The rating is a composite -- a material with 50% rating typically requires 50% of the baseline speed AND gets 50% of the baseline tool life.
Look up your material in this reference to find its machinability rating. Above 100%: use carbide at standard speeds. 50-100%: reduce speeds proportional to the rating. Below 50%: use premium carbide grades (AlTiN-coated, tough substrate), reduce speeds to 30-50% of steel baseline, and expect shorter tool life.
