In today’s competitive manufacturing environment, the efficiency of your CNC equipment is ultimately determined by the quality of your cutting tools. As the workhorses of modern machining, cemented carbide CNC tools offer the perfect balance of hardness, toughness, and wear resistance.
At HAO CARBIDE, we engineer advanced cutting solutions tailored to your specific workpiece materials, helping you maximize tool life and accelerate production cycles.
The Mechanical Superiority of Cemented Carbide
The fundamental rule of metalworking is that the tool must be significantly harder than the workpiece. Utilizing advanced powder metallurgy, our tungsten-carbide based (WC-Co) tools deliver exceptional mechanical properties:
- Extreme Hardness: Our carbide substrates boast a hardness ranging from 89 to 93 HRA, far surpassing traditional high-speed steel.
- High Thermal Stability: Even at cutting temperatures reaching 540°C, our inserts maintain a hardness of 82-87 HRA, preventing premature tool wear during intense operations.
- Superior Bending Strength: Depending on the specific cobalt (Co) binder content, our inserts achieve a bending strength of 1000 to 2350 MPa, effortlessly handling the intense cutting forces of heavy roughing.
ISO-Standardized Carbide Grades for Every Material
Matching the tool’s physical and chemical properties to the workpiece is critical for avoiding tool failure. We offer a comprehensive catalog of tungsten carbide inserts aligned with strict ISO machining classifications:
- K-Class (YG Series): Primarily composed of WC-Co. These fine-grained inserts are highly wear-resistant and ideal for machining cast iron, non-ferrous metals, and abrasive non-metallic materials.
- P-Class (YT Series): Formulated with added Titanium Carbide (TiC). They offer superior high-temperature hardness and oxidation resistance, making them perfect for the continuous turning of steel and ductile materials.
- M-Class (YW Series): Incorporating Tantalum/Niobium Carbide (TaC/NbC), this versatile grade delivers excellent comprehensive performance. It is your go-to solution for roughing and interrupted cutting of difficult-to-machine materials.
| Carbide Category | Chemical Composition | ISO Standard | Application Range |
| YT Series | WC-TiC-Co | P | Machining steel, stainless steel, and long-chipping malleable cast iron. |
| YG Series | WC-Co | K | Machining cast iron, chilled cast iron, short-chipping cast iron, hardened steel, and non-ferrous metals. |
| YW Series | WC-TiC-TaC(NbC)Co | M | Machining cast steel, manganese steel, alloy cast iron, austenitic stainless steel, malleable cast iron, free-cutting steel, and heat-resistant steel. |
Advanced CVD & PVD Tool Coatings
Today, approximately 80% of all CNC turning and milling operations utilize coated tools. At HAO CARBIDE, we take tool performance further through advanced surface engineering.
We utilize Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) to apply micro-thin, refractory compounds (such as TiC, TiN, and Al2O3) to our tough carbide substrates. These coated carbide tools drastically reduce the friction coefficient, resist chemical adhesion, and allow for cutting speeds more than double those of uncoated alternatives.
