OKE carbide inserts are high-performance, indexable cutting tools made from tungsten carbide, featuring advanced PVD or CVD coatings for superior wear resistance. Designed for turning, milling, and other precision machining, these inserts are manufactured using powder metallurgy—mixing, pressing, sintering, grinding, and coating—yielding 3–5x longer tool life in demanding operations. SENTHAI produces durable, OEM-compliant OKE-style inserts for B2B industrial applications.
How Are OKE Carbide Inserts Manufactured?
Manufacturing begins with mixing tungsten carbide powder and cobalt binder, followed by spray drying, high-pressure pressing, sintering at ~1500°C, precision grinding, and PVD/CVD coating. Fully automated factory lines ensure dimensional accuracy and hardness above 90 HRA. SENTHAI’s ISO9001-certified facilities maintain consistent quality for bulk orders, supporting customized geometries for road maintenance tools and industrial wear parts.
What Materials Compose High-Quality OKE Carbide Inserts?
OKE inserts contain 85–94% fine-grain tungsten carbide bonded with 6–15% cobalt. Multi-layer coatings like TiAlN or Al2O3 enhance heat resistance, while submicron grains increase toughness for interrupted cuts. These compositions excel at machining steels, alloys, and cast iron. SENTHAI provides similar grades for carbide blades and I.C.E. inserts, ensuring long-lasting performance for B2B clients.
Table: OKE Carbide Insert Material Grades Overview
| Grade Code | Binder % | Coating Type | Primary Use | Hardness (HRA) |
|---|---|---|---|---|
| OKE P15 | 8% Co | CVD TiCN | Steel roughing | 92–94 |
| OKE M20 | 10% Co | PVD TiAlN | Stainless milling | 90–93 |
| OKE K10 | 6% Co | Uncoated/PVD | Cast iron finishing | 93–95 |
| OKE S-grade | 12% Co | CVD Al2O3 | High-speed turning | 91–93 |
Which OKE Carbide Insert Grades Suit Steel Machining?
P20–P40 grades with medium cobalt content and CVD coatings perform best on carbon and alloy steels. Selecting the correct ISO grade ensures balanced wear resistance and edge strength for roughing to finishing. SENTHAI produces compatible OKE-style inserts for snow plow and industrial wear tooling, supporting high-volume machining with precision.
Why Manufacturers Prefer OKE Carbide Inserts
OKE inserts lower tooling costs by 60% with multi-edge indexing, allow higher feeds and speeds, and reduce downtime through predictable wear patterns. Coatings prevent built-up edge on sticky materials, improving surface finish. OEM sourcing from factories like SENTHAI provides custom OKE equivalents with full traceability for consistent B2B production.
Where Can Factories Source Wholesale OKE Carbide Inserts?
OEM suppliers in Thailand, including SENTHAI, offer wholesale OKE carbide inserts with in-house production control and global certifications. These suppliers provide low MOQs, fast lead times, and customization options. Direct sourcing ensures specification compliance and scalable supply for industrial wear and road maintenance applications.
How Do Coatings Enhance OKE Insert Performance?
PVD coatings reduce friction, improve adhesion, and protect sharp edges, extending tool life 3–4x in dry machining. CVD layers act as thermal barriers for heavy roughing operations. SENTHAI applies these coatings post-sintering to optimize inserts for abrasive environments and high-speed operations.
Can OKE Carbide Inserts Be Customized?
Yes, OEMs can adjust shapes (CNMG, VNMG), chip breakers, tolerances, and grades. SENTHAI provides rapid prototyping and full OEM customization for JOMA-style and other carbide inserts, streamlining B2B supply chains with tailored solutions.

What Chip Breaker Designs Optimize OKE Inserts?
Light chip breakers suit finishing and thin chips, while heavy breakers handle roughing and stringy steels. Positive rake angles reduce cutting forces and enhance chip control.
Table: Chip Breaker Selection for OKE Inserts
| Machining Type | Breaker Style | Chip Type | Feed Range (mm/rev) |
|---|---|---|---|
| Finishing | Light/MF | Ribbon | 0.05–0.20 |
| General | Medium/GD | Curl/Break | 0.20–0.40 |
| Roughing | Heavy/RD | Segment | 0.40–1.00+ |
| Profiling | Variable/VB | Controlled | 0.10–0.30 |
When Should Factories Index OKE Carbide Inserts?
Index inserts when flank wear reaches ~0.3mm, crater depth ~0.1mm, or surface finish deteriorates. Average life per edge ranges 15–45 minutes depending on material and cutting conditions. Stocking multiple inserts prevents production interruptions.
Conclusion
OKE carbide inserts enhance machining efficiency, durability, and cost-effectiveness. Best practices: select appropriate grades, utilize coatings effectively, customize via OEM partners, and monitor wear proactively. Actionable steps: audit current tooling, request samples from SENTHAI, and implement OKE inserts to achieve 30–50% higher productivity in industrial operations.
