4-Step Precision Manufacturing Process
Raw Material Processing
Premium Thermo-Lock™ alloy bars are precisely cut and prepared using advanced CNC machining centers with ±0.05mm tolerance.
Carbide Tip Assembly
German carbide tips are bonded using computer-controlled vacuum brazing furnaces ensuring uniform aerospace-grade joint strength.
Heat Treatment
Computer-controlled heat treatment processes ensure optimal hardness (HRC 58-62) and metallurgical properties.
Precision Grinding
Professional CNC grinders precisely grind spiral flutes for optimal chip removal and drilling efficiency.
CNC Machining Centers
Our 40 high-precision 5-axis CNC machining centers form the backbone of production. Each machine delivers ±0.05mm tolerance for steel body processing, shank preparation, and complex geometries—ensuring every drill bit starts with perfect dimensional accuracy.
Computer-Controlled Vacuum Brazing
Unlike common high-frequency welding, we utilize a fully automated vacuum brazing furnace. This process eliminates impurities and ensures every single carbide tip is bonded with maximum, uniform strength, providing a level of reliability that manual welding simply cannot match.
Heat Treatment Furnaces
Computer-controlled vacuum heat treatment furnaces precisely control hardness profiles. Our automated quenching systems achieve HRC 58-62 consistency across millions of units, ensuring predictable performance in the field.
Precision Grinders
Professional CNC grinders with diamond wheels precision-grind spiral flutes for optimal chip evacuation. Our proprietary flute geometry reduces drilling friction by 23%, extending tool life and improving penetration speed.
Quality Inspection Lab
Our metrology lab features coordinate measuring machines (CMM), hardness testers, and automated optical inspection. Every batch undergoes 12-point verification—achieving a 98.5% first-pass quality rate.
Smart Packaging Lines
High-speed automated packaging lines handle 30,000+ units daily with custom branding capabilities. Integrated QR tracking provides full traceability from raw material to delivery—supporting OEM partners worldwide.
