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, hole size, drilling depth, e condizioni di lavorazione.
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. Tuttavia, the final tool design depends on the graphite material, hole requirements, condizione della macchina, e la quantità dell'ordine.
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.
Per questo motivo, 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. Invece, OMIST mainly recommends it for graphite, graphite electrodes, graphite molds, and other abrasive non-ferrous applications. Perciò, 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.
Perciò, graphite drilling usually requires a tool with suitable edge strength, stable geometry, and a wear-resistant coating. The drill design should also match the hole diameter, hole depth, condizione della macchina, and dust removal method.
Graphite Is Abrasive During Drilling
Graphite can cause fast cutting-edge wear during drilling. Inoltre, graphite dust and chip control may affect hole quality, vita dell'utensile, e stabilità della lavorazione.
Di conseguenza, graphite drilling should not rely only on a general-purpose carbide drill. OMIST selects the cutting edge, disegno del flauto, point geometry, 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.
For graphite drilling, this coating can help protect the cutting edge and improve wear resistance. Tuttavia, the final performance also depends on the graphite grade, drill geometry, rigidità della macchina, and cutting parameters.
OMIST does not recommend choosing a drill only by coating color. Invece, 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. Perciò, the drill point, bordo tagliente, disegno del flauto, 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
Solid Carbide Substrate
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.
Inoltre, the carbide grade can be selected according to the application. This allows the tool to balance edge strength, resistenza all'usura, 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, graphite molds, 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. Nel frattempo, other diameters, flute lengths, shank sizes, and overall lengths can be produced according to the customer’s requirements.
Custom Drill Geometry
Graphite drilling may require a special drill point, bordo tagliente, disegno del flauto, or neck structure. Per questo motivo, OMIST reviews the application before confirming the final geometry.
The correct design is not selected only by drill diameter. Invece, it should match the graphite material, hole depth, rigidità della macchina, chip control method, and required hole quality.
| Graphite Drilling Condition | Design Focus |
| Small hole drilling | Tool runout, point strength, and shank rigidity |
| Deeper hole drilling | Lunghezza del flauto, chip removal, and drilling stability |
| Lavorazione elettrodi di grafite | Wear resistance, hole accuracy, and edge protection |
| Dry or dust-controlled machining | Chip evacuation and dust removal condition |
| Non-standard graphite parts | Diametro personalizzato, lunghezza, point geometry, and coating |
Before production, OMIST will confirm the drill geometry, CVD diamond coating, and final dimensions according to the customer’s drawing, graphite material, hole size, e condizioni di lavorazione.
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, stable machining, 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. Perciò, a standard drill may not always match the required application.
OMIST can review the drawing, graphite grade, and machining condition before recommending the drill diameter, geometria, and coating.
Precision Small Hole Drilling
Small hole graphite drilling requires better control of tool runout, evacuazione truciolo, e stabilità al taglio. The reference small-diameter images can represent this type of drilling requirement.
Tuttavia, 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. In these cases, customers can provide drawings, samples, or existing tool specifications.
Our team will then evaluate whether a custom CVD diamond coated carbide drill can be produced for the application.
Custom Specifications for Diamond Coated Drill Bits
OMIST can supply standard and custom diamond coated drill bits according to different graphite drilling requirements. The images on this page show reference products only. Actual specifications will be confirmed according to the workpiece and machining conditions.
Product images and dimensions are shown as reference examples. OMIST will confirm the final CVD diamond coating, drill geometry, and size before production.
The actual coating appearance, drill geometry, misurare, and packaging may vary according to the graphite material, disegno, quantity, and customization requirements.
How to Choose a Diamond Coated Drill Bit for Graphite
Graphite Material Grade
Different graphite materials may have different hardness, density, and abrasiveness. Perciò, the graphite grade or material description should be provided before tool selection.
If the customer does not know the exact graphite grade, photos, samples, or application details can also help with evaluation.
Hole Diameter and Hole Depth
Hole size is one of the most important details for a quotation. Please provide the required hole diameter, hole depth, and whether the hole is a through hole or blind hole.
For small holes, the required tolerance and machine runout should also be considered.
Machine and Machining Condition
Graphite machining may involve dry cutting, dust collection, air blowing, or other chip control methods. Perciò, the machine condition and dust removal method should be explained when possible.
Please also provide the current cutting problem if the existing tool wears too quickly or produces unstable hole quality.
Quantity and Drawing Requirement
For custom diamond coated drills, quantity affects production planning, coating arrangement, and lead time. A drawing or sample is helpful, especially for non-standard tool dimensions.
When the drawing is not available, customers can provide the hole size, graphite material, drilling depth, and current tool photo.
