OMIST designs this diamond coated drill bit for graphite drilling and abrasive non-ferrous machining applications. It uses a solid carbide substrate, and OMIST can supply it with CVD diamond coating according to the customer’s graphite material, tamanho do furo, drilling depth, e condição de usinagem.
For industrial graphite drilling, some buyers may also search for this tool as an industrial diamond drill bit or a diamond coated carbide drill bit. No entanto, the final tool design depends on the graphite material, hole requirements, condição da máquina, e quantidade do pedido.
Standard and custom specifications are available. OMIST will confirm the final drill design before production according to the customer’s application requirements.
CVD Diamond Coated Drill Bit for Graphite Drilling
Manufacturers use a CVD diamond coated drill bit when graphite drilling requires better wear resistance and stable hole machining. Graphite is abrasive during cutting, so ordinary tool edges may wear quickly under unsuitable machining conditions.
Por esta razão, OMIST supplies solid carbide drills with CVD diamond coating for graphite machining. The carbide body provides rigidity, while the diamond coating helps protect the cutting edge during abrasive graphite drilling.
This product is not a general-purpose drill for all metals. Em vez de, OMIST mainly recommends it for graphite, eletrodos de grafite, moldes de grafite, and other abrasive non-ferrous applications. Portanto, OMIST selects the final tool design according to the actual workpiece material and drilling requirements.
Why Use a Diamond Coated Drill Bit for Graphite?
Graphite drilling creates different challenges from steel or stainless steel drilling. The material is abrasive, and graphite dust may also affect chip control, hole quality, and tool stability.
Portanto, graphite drilling usually requires a tool with suitable edge strength, geometria estável, and a wear-resistant coating. The drill design should also match the hole diameter, profundidade do furo, condição da máquina, and dust removal method.
Graphite Is Abrasive During Drilling
Graphite can cause fast cutting-edge wear during drilling. Além disso, graphite dust and chip control may affect hole quality, vida útil da ferramenta, e estabilidade de usinagem.
Como resultado, graphite drilling should not rely only on a general-purpose carbide drill. OMIST selects the cutting edge, desenho de flauta, geometria do ponto, and coating according to the actual application.
CVD Diamond Coating Helps Reduce Tool Wear
CVD diamond coating is different from DLC, Ta-C, or common nano coatings. Customers often choose it for applications where abrasive wear is a major problem.
Para perfuração de grafite, this coating can help protect the cutting edge and improve wear resistance. No entanto, the final performance also depends on the graphite grade, geometria da broca, rigidez da máquina, e parâmetros de corte.
OMIST does not recommend choosing a drill only by coating color. Em vez de, we review the workpiece material and machining condition before confirming the coating and geometry.
Stable Geometry Supports Hole Quality
A graphite drill bit should cut smoothly and remove chips effectively. Portanto, the drill point, ponta, desenho de flauta, and shank rigidity must be considered together.
For small-diameter holes, tool runout and machine stability are especially important. A suitable drill design can support more consistent hole machining when the machine and cutting conditions are properly controlled.
Key Features of Our Diamond Coated Carbide Drill Bits
Substrato Sólido de Carboneto
OMIST uses a solid tungsten carbide substrate for this drill type. The carbide body provides the rigidity needed for CNC drilling and helps the tool maintain stability during graphite machining.
Além disso, the carbide grade can be selected according to the application. This allows the tool to balance edge strength, resistência ao desgaste, and drilling stability.
CVD Diamond Coating for Graphite
This product can be supplied with real CVD diamond coating. It is not described as DLC, Ta-C, TiAlN, AlTiN, or a common nano coating.
Customers mainly use this coating for graphite and abrasive non-ferrous materials. When customers are drilling graphite electrodes, moldes de grafite, or custom graphite components, a CVD diamond coated drill may be a suitable option.
For general metal drilling, TiAlN, AlTiN, nano coatings, or other coating options may be more suitable. Our Carbide Drill Bits page covers those applications better.
Small Diameter and Custom Sizes
The reference images show a small-diameter drill structure. This helps customers understand the tool type, but it does not limit the available specifications.
Small-diameter diamond coated drills can be used for precision graphite holes, small graphite components, and custom hole machining. Enquanto isso, other diameters, comprimentos de flauta, tamanhos de haste, and overall lengths can be produced according to the customer’s requirements.
Custom Drill Geometry
Graphite drilling may require a special drill point, ponta, desenho de flauta, or neck structure. Por esta razão, OMIST reviews the application before confirming the final geometry.
The correct design is not selected only by drill diameter. Em vez de, it should match the graphite material, profundidade do furo, rigidez da máquina, chip control method, and required hole quality.
| Graphite Drilling Condition | Design Focus |
| Small hole drilling | Excentricidade da ferramenta, point strength, and shank rigidity |
| Deeper hole drilling | Comprimento da flauta, remoção de cavacos, and drilling stability |
| Usinagem de eletrodo de grafite | Resistência ao desgaste, hole accuracy, e proteção de borda |
| Dry or dust-controlled machining | Chip evacuation and dust removal condition |
| Non-standard graphite parts | Diâmetro personalizado, comprimento, geometria do ponto, e revestimento |
Antes da produção, OMIST will confirm the drill geometry, CVD diamond coating, and final dimensions according to the customer’s drawing, graphite material, tamanho do furo, e condição de usinagem.
Diamond Coated Drill Bit Applications in Graphite Machining
Graphite Electrode Drilling
Graphite electrodes are widely used in EDM applications. These parts may require accurate holes, usinagem estável, and good edge wear resistance.
A custom diamond coated drill bit can be considered when graphite electrode drilling creates abrasive wear or unstable hole quality.
Graphite Mold and Die Components
Graphite molds, die components, and fixtures may have different hole diameters and depths. Portanto, a standard drill may not always match the required application.
OMIST can review the drawing, grau de grafite, and machining condition before recommending the drill diameter, geometria, e revestimento.
Precision Small Hole Drilling
Small hole graphite drilling requires better control of tool runout, evacuação de cavacos, e estabilidade de corte. The reference small-diameter images can represent this type of drilling requirement.
No entanto, the final size is not limited to the displayed product. Other micro and small-diameter drill sizes can be customized according to the workpiece.
Custom Graphite Components
Some graphite parts require non-standard holes, special depth, or strict component design. Nestes casos, customers can provide drawings, amostras, or existing tool specifications.
Our team will then evaluate whether a custom CVD diamond coated carbide drill can be produced for the application.
