Company Profile
We are a specialized manufacturer of hole-cutting tools headquartered in China. Our company operates a modern manufacturing facility spanning over 50,000 square meters. With more than a decade of deep expertise in the industry, we have established ourselves as specialists in the field of hole machining, dedicated to the R&D and production of a comprehensive range of industrial-grade cutting tools.
Our core product lines include:
- High-Hardness Drill Bits: Carbide drill bits, center drills, and step drills.
- Precision Reaming Tools: Standard reamers and custom-engineered high-precision reamers.
- Thread Machining Series: High-performance cut taps and form taps.
Heavy-Duty Cutting Solutions: Annular cutters (core drills), boring systems, and various non-standard combination tools.
Our factory has introduced multiple state-of-the-art, fully automated 5-axis CNC grinding production lines, ensuring that every cutting tool meets the most exacting standards regarding both geometric parameters and surface coating treatments. We employ a professional workforce of over 300 individuals, including an elite team of senior R&D engineers and skilled technical craftsmen. Whether your project requires complex, non-standard custom orders or large-scale standardized mass production, we are equipped to fulfill your needs with exceptional efficiency and precision.
Leveraging our exceptional global supply chain network, we select the world’s finest raw materials—such as imported high-quality carbide and high-speed steel—to ensure the durability and cutting efficiency of our tools. Currently, our products are exported to numerous countries and regions, including the United States, the United Kingdom, the Middle East, Southeast Asia, Japan, and South Korea.
Quality Control
Every tool passes through six mandatory quality gates before shipment. Our process is designed to catch defects at the earliest possible stage, minimizing waste and ensuring only conforming tools reach our customers.
Incoming Material QC
All carbide blanks tested for hardness (HRA 90–92), transverse rupture strength, and grain size. Certificate of conformance required from all suppliers. Batch rejection rate maintained below 0.5%.
In-Process Inspection
Automated measurement after each grinding pass using Renishaw probing. Statistical process control (SPC) charts monitored in real-time. Out-of-spec parts flagged and quarantined immediately.
Coating Verification
Coating thickness measured by X-ray fluorescence (XRF) after every PVD cycle. Adhesion verified by Rockwell indentation test per ISO 26443. 100% visual inspection for color uniformity and surface defects.
Final CMM Inspection
100% dimensional inspection on Zeiss CMM for all critical dimensions: diameter, runout (≤0.003mm), helix angle, edge preparation radius. Full inspection report issued per batch with Cpk values.
Cutting Performance Test
Representative samples (5% per batch) undergo cutting trials on in-house CNC machining centers. Tool life (number of holes/passes), surface finish (Ra), and dimensional accuracy of machined parts verified against specification.
Traceability & Packaging
Each tool labeled with batch number, material grade, coating type, and inspection date. Full traceability from raw material lot to shipment. Individual anti-corrosion packaging with shock-absorbing foam for export.
