Frequently Asked Questions
It’s a universal grade (PC5300) suitable for steel (P), stainless steel (M), cast iron (K), and exotics (S). The TiAlN coating resists heat and abrasion across these material families.
It’s a square SPMT-style insert (90°). Inscribed circle is approximately 11 mm (0.433"), thickness is 4 mm (0.157"), corner radius is 0.8 mm, with a relief angle around 11°.
The “PD” chipbreaker is designed for general hole-making applications, giving strong cutting edge integrity and reliable chip control across steels, stainless steels, and cast irons.
Yes. While it's part of Korloy’s King Drill (indexable hole-making system), the PC5300 grade and SPMT geometry are versatile enough for turning, milling, grooving, or parting—where similar chip control features are required.
PC5300 combines a fine-grain, toughened substrate with a PVD TiAlN coating that delivers superior wear resistance, oxidation resistance, and chipping resistance—extending tool life, reducing re-tooling downtime, and improving surface finish consistency.
