Landun CNC Tool focuses on the development and manufacturing of solid carbide drilling tools for industrial hole-machining applications.
Our product range covers standard carbide drills, micro carbide drills, deep-hole carbide drills, flat-bottom drills, step drills, spot drills, center drills, double-ended drills, and drawing-based custom drilling tools.
With a 3,000-square-meter production facility, precision CNC grinding equipment, coating capability, and dedicated inspection instruments, we support both standard production and customized tooling projects.
Our team pays close attention to the factors that directly influence drilling performance, including carbide material, point geometry, flute design, edge preparation, coating selection, coolant configuration, chip evacuation, hole accuracy, and tool consistency.
From initial tool design and precision grinding to edge inspection and final quality control, each production stage is managed to support stable performance and repeatable quality.
Landun CNC Tool operates a 3,000-square-meter production facility dedicated to the manufacturing, inspection, and development of solid carbide drilling tools.
The factory layout covers CNC tool grinding, cutting-edge preparation, coating and surface treatment, dimensional inspection, appearance inspection, packaging, and order management.
A structured production process helps us handle standard carbide drill orders, small-batch customized tools, prototype development, and repeat production while maintaining consistent manufacturing control and reliable lead times.
Advanced tool grinding machines, PVD coating equipment, and inspection systems supporting the complete production process from manufacturing to final quality control.
From precision grinding and controlled edge preparation to application-matched coating and final inspection, each production stage is managed to support consistent carbide drill geometry, cutting-edge quality, and batch repeatability.
Manual drill-point honing and automatic rubber-bonded diamond abrasive polishing help strengthen the cutting edge, reduce microscopic defects, and control edge preparation within ±0.003 mm.
ALTISIXN, HSR118, DLC, and uncoated surface options are selected according to the workpiece material, cutting heat, chip adhesion, abrasive wear, and machining requirements.
WALTER HELICHECK PLUS is used to inspect critical tool profiles and geometric features with accuracy control within 3 μm. Cutting edges are also checked at up to 300x magnification for chipping, saw-tooth defects, grinding marks, and visible damage.
Our engineering work is based on actual drilling requirements rather than applying the same tool design to every application.
We review the workpiece material, hole diameter, drilling depth, entry condition, machine rigidity, spindle runout, coolant method, chip formation, and production target before recommending or developing a carbide drill solution.
This application-oriented approach supports both the improvement of standard carbide drills and the development of customized tools based on customer drawings, samples, or existing machining problems.
Reliable carbide drill performance depends on more than the final diameter. Carbide material, drill geometry, cutting-edge condition, edge preparation, coating quality, and dimensional consistency must be controlled throughout the manufacturing process.
Landun CNC Tool carries out inspections at critical production stages to identify deviations before the tools are released for coating, final inspection, packaging, and shipment.
Our mission is to provide reliable solid carbide drilling tools that help manufacturers improve hole accuracy, machining stability, tool utilization, and production efficiency.
We aim to create practical value through consistent manufacturing, application-oriented tool design, strict inspection, and responsive customer support.
Our vision is to become a trusted carbide drill manufacturing partner for industrial customers worldwide.
We seek to build long-term cooperation through dependable product quality, continuous process improvement, customized engineering capability, and responsible service.
