Electroplated Drill Bit is a drilling tool that uses an electroplating process to cover the surface of the drill with a special coating. It is mainly used for high-precision and high-strength material processing. Its functions and application features are as follows:
Core Function
Enhance Wear Resistance
The electroplating layer (such as diamond particles, titanium nitride, tungsten carbide, etc.) significantly improves the surface hardness of the drill bit and extends its service life, especially when processing hard and brittle materials (such as glass fiber, ceramics, and composite materials).
Improve Cutting Efficiency
The electroplating coating can reduce the friction between the drill bit and the material, reduce cutting resistance, increase drilling speed and efficiency, and reduce heat accumulation.
Adapt to Complex Materials
Designed for high-hardness and high-wear-resistant materials, such as:
PCB circuit boards (glass fiber epoxy resin)
Ceramic substrates
Carbon fiber composite materials
Hardened steel or alloy
Precision Machining
Electroplated drill bits are usually used for small apertures (such as less than 0.1mm) and high-precision drilling scenarios (such as electronic components and micro-electromechanical systems).
Corrosion resistance and high temperature resistance
The coating can resist chemical corrosion and high temperature oxidation, and is suitable for humid, high temperature or corrosive environments.
Typical application scenarios
Electronic industry: PCB circuit board drilling (through hole, blind hole), microelectronic component processing.
Aerospace: carbon fiber composite parts, titanium alloy structural parts drilling.
Precision machinery: high-precision molds, ceramic bearings, optical device processing.
Medical equipment: surgical instruments, implant micro hole processing.
Electroplating process advantages
Uniform coating: Electroplating technology ensures uniform distribution of coating on the drill surface, avoiding the shedding problem of traditional spraying.
Customization: Coating materials (such as diamond, diamond-like carbon DLC) and thickness can be adjusted according to needs.
Environmental protection: Compared with chemical vapor deposition (CVD), electroplating process has lower energy consumption and less pollution.
Notes
Applicable material restrictions: Electroplated drill bits are more suitable for hard and brittle materials, and may excessively wear the coating on soft materials (such as pure aluminum and plastic).
High cost: The cost of electroplating process and coating materials is high, which is suitable for precision processing of high value-added products.
Maintenance requirements: Avoid impact or improper operation to prevent coating peeling.
Summary
Electroplated drilling drills are far superior to ordinary drills in hardness, wear resistance and precision through surface coating technology. They are the core tools for precision drilling in high-end manufacturing, especially suitable for fields with strict process requirements such as electronics and aerospace.
