View Product detailsIndustrial drilling and cutting demand strict material properties. Here is how our engineering chemistry delivers unparalleled resistance and longevity.
Our solid carbide substrates rely on fine and submicron (0.4µm to 0.8µm) tungsten carbide particles. The tighter the grain size, the more uniform the cobalt binder distribution, leading to a massive boost in hardness without compromising on fracture toughness. This prevents micro-chipping along the cutting edges during high-feed operations.
Cobalt serves as the vital metallic matrix binding the hard WC particles. Our engineers carefully control cobalt ratios between 6% and 12% depending on the tool's intended role. Lower cobalt content yields maximum hardness (up to 94 HRA) for processing high-hardness steels, while higher cobalt levels boost transverse rupture strength (TRS) for heavy-duty twist drills.
To resist temperatures exceeding 900°C at the cutting interface, our tools utilize advanced coatings such as AlTiN (Aluminum Titanium Nitride) and TiAlN nanocomposites. These thin coatings form an aluminum-oxide layer under thermal stress, effectively shielding the underlying tungsten carbide from oxidation, thermal shock, and crater wear.

Every single drill bit and rotary burr undergoes a rigorous, fully monitored engineering process to achieve structural integrity.
We mix tungsten carbide, cobalt, rare elements, aviation gasoline, and alloy balls in high-energy ball mills to homogenize the powder matrix.
The wet slurry is carefully dried. We introduce specific ginseng gum and completely filter out the aviation gasoline to prepare press-ready powders.
Using ultra-precise mechanical and isostatic molding presses, we mold the raw tungsten carbide powder into dense green tool blanks.
Blanks undergo High Isostatic Pressing (HIP) sintering at temperatures up to 1450°C, compressing pores and achieving final hardness.
We adopt advanced, industry-grade 5-axis CNC gear grinding machines to cut high-efficiency gear flutes and precision relief angles.
We perform comprehensive micrometric inspections, utilizing advanced optical comparators, ultrasonic defect detectors, and metallurgical analyzers to guarantee every single batch meets rigorous industrial standards.
As a professional OEM & ODM solution service provider, we focus on providing customized carbide tool manufacturing services to global enterprise customers.
Our engineering team handles your request end-to-end: from custom structural design, substrate formulation adjustments, and unique tool geometry design, to high-performance PVD coating selections. We support small-batch custom prototyping all the way to massive high-volume plant production runs.
