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.
ด้วยเหตุนี้, 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. แทน, OMIST mainly recommends it for graphite, ขั้วไฟฟ้ากราไฟท์, แม่พิมพ์กราไฟท์, and other abrasive non-ferrous applications. ดังนั้น, 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.
ดังนั้น, 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, สภาพเครื่อง, and dust removal method.
Graphite Is Abrasive During Drilling
Graphite can cause fast cutting-edge wear during drilling. นอกจากนี้, graphite dust and chip control may affect hole quality, อายุการใช้งานของเครื่องมือ, และความเสถียรของเครื่องจักร.
ส่งผลให้, graphite drilling should not rely only on a general-purpose carbide drill. OMIST selects the cutting edge, การออกแบบขลุ่ย, 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. อย่างไรก็ตาม, the final performance also depends on the graphite grade, drill geometry, ความแข็งแกร่งของเครื่องจักร, and cutting parameters.
OMIST does not recommend choosing a drill only by coating color. แทน, 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. ดังนั้น, the drill point, คมตัด, การออกแบบขลุ่ย, 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
พื้นผิวโซลิดคาร์ไบด์
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.
นอกจากนี้, the carbide grade can be selected according to the application. This allows the tool to balance edge strength, ความต้านทานการสึกหรอ, 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, อัลทิน, or a common nano coating.
Customers mainly use this coating for graphite and abrasive non-ferrous materials. When customers are drilling graphite electrodes, แม่พิมพ์กราไฟท์, or custom graphite components, a CVD diamond coated drill may be a suitable option.
For general metal drilling, TiAlN, อัลทิน, 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. ขณะเดียวกัน, other diameters, ความยาวขลุ่ย, 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, คมตัด, การออกแบบขลุ่ย, or neck structure. ด้วยเหตุนี้, OMIST reviews the application before confirming the final geometry.
The correct design is not selected only by drill diameter. แทน, it should match the graphite material, hole depth, ความแข็งแกร่งของเครื่องจักร, 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 | ความยาวขลุ่ย, chip removal, and drilling stability |

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, การตัดเฉือนที่มั่นคง, 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. ดังนั้น, 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, เรขาคณิต, and coating.
Precision Small Hole Drilling
Small hole graphite drilling requires better control of tool runout, chip evacuation, และความเสถียรในการตัด. The reference small-diameter images can represent this type of drilling requirement.
อย่างไรก็ตาม, 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, ตัวอย่าง, or existing tool specifications.
Our team will then evaluate whether a custom CVD diamond coated carbide drill can be produced for the application.
