The SPMT 050204-PD PC5300 is a universal, PVD TiAlN-coated carbide insert with PD chipbreaker — engineered for stable drilling across steel, stainless, and cast iron. Trusted for longer tool life, chip control, and cost savings.
Take your drilling performance to the next level with the SPMT 050204-PD PC5300 carbide insert, engineered for stability, accuracy, and cost efficiency. Designed with a PD chipbreaker and coated in a PVD TiAlN layer, this insert delivers reliable chip evacuation, high wear resistance, and consistent performance across multiple materials.
The PC5300 grade is a proven universal solution, handling steel, stainless steel, cast iron, and HRSA alloys with ease. Its fine-grain carbide substrate combined with advanced coating ensures excellent edge stability and reduced risk of chipping, even under demanding conditions.
Hook / Attention Line
“When you switch to SPMT 050204-PD PC5300, you’re investing in fewer tool changes, smoother cycles, and lower cost per hole.”
Key Features & Specs
-
Designation / Geometry: SPMT (square, 90°) with PD chipbreaker — versatile for drilling and peripheral cutting.
-
Grade & Coating: PC5300 (PVD TiAlN) — a universal grade suited for steel, cast iron, stainless, and even HRSA / exotic alloys.
-
Corner Radius: ~ 0.016" (≈ 0.4 mm)
-
Thickness / Insert Dimensions: ~ 0.094" thickness, inscribed circle ~ 0.2008" (≈ 0.201")
-
Chipbreaker Type: PD – designed for stable cutting and chip control in general machining applications (steel, stainless, cast iron)
Recommended Application: Drilling (especially in Korloy “King Drill” systems) but also suitable for turning, milling, grooving, parting, and threading in lower-interrupt contexts.
Why It’s a Best Seller
-
Universal versatility — one grade (PC5300) handles multiple materials (P / M / K / S classes), reducing tool inventory and simplifying tool strategies.
-
Superior edge strength & chipping resistance — the combination of ultra-fine substrate and PVD coating gives excellent wear resistance, oxidation resistance, and reduces chipping even under harder conditions.
-
Stable machining & lower downtime — consistent chip control and edge stability mean fewer tool failures, more predictable cycles, and less unplanned stoppage.
-
Better surface finish & dimensional consistency — in tests, drills using SPMT inserts show more uniform hole diameters (beginning, middle, end) versus competitor inserts.

Frequently Asked Questions
It’s a universal grade — ideal for steel, stainless steel, cast iron, and some HRSA / exotic alloys. PC5300 is designed to span P, M, K, S classes.
No — while it is optimized for drilling (especially in Korloy King Drill systems), its geometry and chipbreaker design also allow usage in light turning, milling, grooving, parting, and threading in suitable setups.
The PD chipbreaker is engineered for stable cutting, efficient chip evacuation, and resistance to chipping under general machining conditions (especially steel, stainless, cast iron)
Because of its high wear resistance, edge stability, and universal material compatibility, you’ll change inserts less often, reduce downtime, and minimize the number of different grades you need in stock — all contributing to lower cost per part.
In Korloy’s King Drill line, SPMT 050204 is used for drills in the ~ Ø0.562″ to Ø0.625″ (≈ 14.3 to 15.9 mm) range, per Korloy’s specification matrix
