Why Grade PC5300

Korloy’s PC5300 sits between general-purpose and high-performance offerings — strong enough for production rough machining on cast iron, conservative enough to forgive the occasional spike in feed rate. Diamond layer keeps cutting temperatures workable.

Features & Benefits

100% Genuine Korloy – Original product with full quality guarantee, traceable batch.
Edge Stability – Substrate chemistry tuned to limit micro-chipping on cast iron interruptions.
Thermal Resistance – diamond layer holds hardness above typical cutting-zone temperatures.
Professional CNC Tooling – Compatible with major CNC machine brands (Mazak, DMG, Haas, Doosan).
Ready Stock – In-stock for same-day dispatch from our CNC tooling warehouse.
Optimized Chip Breaker – Engineered chip geometry reduces re-cutting and machine downtime.

Recommended Applications

Rough Machining of cast iron in production CNC lines
Performs across a range of cutting speeds and feed rates
Suitable for both wet and dry machining conditions
Effective in interrupted and continuous cutting passes

Buying Considerations

Single-pack option — useful for prototype runs or qualification before bulk commitment. Entry-tier pricing makes this a low-risk option for trialing Korloy tooling on a new material.

Tip: Match this insert to a holder whose seat matches the ISO designation. If you’re unsure, send us the holder model and we’ll confirm compatibility before shipping.
