Why It’s a Best Seller:
Why It’s a Best Seller
Because in real-shop terms it means:
-
Less downtime: you change inserts less often thanks to excellent wear resistance and thermal stability.
-
Better surface finish: PC5300’s fine grain substrate and PVD coating help reduce built-up edge, maintain sharper cutting edge longer.
-
High wear & oxidation resistance: even under elevated temperatures or aggressive cutting, the insert holds up.
-
Versatility: one grade covers many materials and many kinds of milling work, so inventory can be simpler.

Frequently Asked Questions
PC5300 is a universal grade for materials such as carbon & alloy steels, stainless steels, and cast irons. It handles both continuous and somewhat interrupted milling.
PDER is one of Korloy’s chip breaker styles (in the “R”-family) tuned for medium to finishing milling cuts. It controls chips well, lowers cutting forces, and helps with finish and tool life.
PC5300 emphasizes high temp wear resistance & universal application; PC5400 leans more toward toughness, especially useful for interrupted cuts or roughing where chipping or impact is more pronounced.
Speeds/feeds depend heavily on material, depth of cut, coolant, and machine. With PC5300, for steel/stainless under medium cutting you can push for higher cutting speeds while maintaining tool life. (Refer to Korloy’s cutting condition tables for specific values.)
Though you might pay more upfront, this insert’s coating and grade mean fewer replacements, less downtime, superior finish, and less scrap. Over time, cost per part drops significantly.
