Korloy MRMN300-M H01 – Carbide Insert

The Korloy MRMN300-M H01 is purpose-built for shops running interrupted cutting on steel. Korloy’s tin substrate balances wear resistance and toughness, making this carbide insert a dependable choice across mixed-batch CNC work.

This Diamond 86° profile suits applications where chip control and tool rigidity both matter — the cross-section keeps the cutting edge supported even under intermittent loads.

What machinists are saying about MRMN300-M: Korloy's MGT system allows a machinist to apply one tool against many applications and reduces the number of tools. MGT tools have a flat geometry on its cutting edge to ensure an excellent surface roughness. Even in high feed applications by using a wiper function, Korloy ensures excellent surface roughness.

Grade H01 Performance Profile

Operators running steel with the Korloy H01 typically report stable wear progression rather than catastrophic edge loss. The tin system is the reason: it slows abrasion at the rake face while keeping the substrate from softening at the cutting zone.

Features & Benefits

100% Genuine Korloy – Original product with full quality guarantee, traceable batch.
Precision Ground – Tight dimensional tolerances for repeatable performance across batches.
Ready Stock – In-stock for same-day dispatch from our CNC tooling warehouse.
Professional CNC Tooling – Compatible with major CNC machine brands (Mazak, DMG, Haas, Doosan).
Edge Stability – Substrate chemistry tuned to limit micro-chipping on steel interruptions.
Optimized Chip Breaker – Engineered chip geometry reduces re-cutting and machine downtime.

Recommended Applications

Interrupted Cutting of steel in production CNC lines
Holds dimensional tolerance over multiple indexings (insert)
Designed for shop conditions typical of Korloy tooling users worldwide
Pairs well with through-coolant setups for chip evacuation

Buying Considerations

Single-pack option — useful for prototype runs or qualification before bulk commitment. Mid-tier pricing reflects Korloy’s production-grade tolerances rather than economy substrate.

Reminder: Holder rigidity, lead angle, and approach all influence how this insert wears. Pair with a holder rated for the same cutting forces.
