정밀 드릴링용 솔리드 초경 드릴 비트

Solid carbide drill bits combine high rigidity with good wear resistance. 결과적으로, manufacturers often use them for CNC machining, precision component production, and repetitive metal drilling.

Compared with conventional general-purpose drills, a solid carbide drill provides better dimensional stability under suitable machining conditions. It can also support consistent hole quality during batch production.

하지만, one drill design cannot suit every material. 강철, 스테인레스 스틸, 주철, 알류미늄, and copper have different cutting characteristics. 그러므로, we select the cutting edge, 플루트 디자인, point geometry, and coating for the actual application.

OMIST supplies both standard and custom carbide twist drills. Customers can order a reference size directly, or OMIST can manufacture a non-standard drill from a drawing, sample, or detailed machining request.

Key Features of Our Carbide Drill Bits

Solid Tungsten Carbide Construction

OMIST manufactures the drill body from solid tungsten carbide. This material provides the rigidity required for stable CNC drilling.

게다가, we select the carbide grade according to the workpiece material and machining conditions. A suitable balance between wear resistance and edge strength is important, especially when hole depth, material hardness, or machine stability changes.

Precision-Ground Cutting Geometry

We precision-grind the drill point, 최첨단, and flutes. Consequently, the tool can enter the workpiece more steadily and remove chips through the helical flutes.

We select the drill geometry according to several factors:

• 공작물 재료
• Material hardness
• Hole diameter
• Hole depth
• Through-hole or blind-hole machining
• 기계 강성
• Cooling method
• Required hole tolerance

The reference products shown in the images use a two-flute twist drill design. Nevertheless, other geometries may be produced when the application requires a different solution.

Coating Options for Different Applications

Coated carbide drill bits can provide additional wear resistance, 내열성, or lower friction. 하지만, the coating must match the workpiece material.

예를 들어, a coating suitable for steel may not be the best option for aluminum or copper. 그러므로, the coating is selected after the machining application has been reviewed.

Uncoated options may also be recommended for certain non-ferrous materials or special drilling conditions.

Standard and Custom Specifications

Standard carbide drill sizes are available for common applications. 그 동안에, non-standard specifications can be produced for special components, restricted machine spaces, or specific hole requirements.

Custom options include:

• Drill diameter
• 플루트 길이
• Cutting length
• Shank diameter
• 전체 길이
• 목 길이
• Point geometry
• Point angle
• Flute design
• 코팅
• Laser marking
• Product label
• 포장

This flexibility allows the drill to be matched more closely to the customer’s machining process.

Carbide Drill Bits for Different Workpiece Materials

Carbide Drill Bits for Steel and Alloy Steel

Steel and alloy steel are common materials in CNC drilling. 하지만, their hardness, alloy content, and heat-treatment condition can vary greatly.

이러한 이유로, customers should provide the exact material grade and hardness whenever possible. The carbide grade, cutting geometry, and coating can then be selected more accurately.

Suitable applications may include:

• Carbon steel parts
• Alloy steel components
• Mold and die parts
• Mechanical components
• 자동차 부품
• General engineering parts

Carbide Drill Bits for Stainless Steel

Stainless steel can generate heat and material adhesion during drilling. 게다가, poor chip evacuation may reduce hole quality or damage the cutting edge.

A suitable carbide drill for stainless steel should provide stable cutting and effective chip removal. The coating and geometry should also be selected according to the stainless steel grade, hole depth, 기계 상태, and coolant supply.

Before production, please confirm the following details:

• Stainless steel grade
• Material hardness
• Hole diameter
• Hole depth
• Through hole or blind hole
• Coolant condition
• Required quantity

Carbide Drill Bits for Cast Iron

Cast iron applications require good wear resistance and stable cutting edges. 하지만, gray cast iron, ductile iron, and other cast materials may need different drill designs.

그러므로, please provide the cast iron type before we recommend a suitable tool. We may also adjust the coating according to the material’s abrasiveness and the required production volume.

Carbide Drills for Aluminum and Copper Alloys

알류미늄, 구리, and other non-ferrous materials can adhere to the cutting edge. 결과적으로, chip evacuation and surface friction must be considered carefully.

A polished flute, suitable edge geometry, or low-friction coating may be recommended. In some cases, an uncoated carbide drill can also be considered.

The final design depends on:

• Alloy grade
• Chip characteristics
• Hole depth
• Coolant condition
• Hole finish requirement
• Production quantity

Carbide Drills for Hardened Materials

Harder workpiece materials require careful tool selection. The material hardness must be confirmed before production because not every carbide drill is suitable for every hardness range.

Please provide the actual HRC value, material grade, hole size, and drilling depth. Our team will then evaluate whether a suitable carbide grade, 코팅, and drill geometry can be supplied.

Coating Selection for Carbide Drill Bits

The coating should not be selected only by its color. 대신에, it should be chosen according to the material, 경도, drilling temperature, friction, cooling condition, and required tool performance.

Wear-Resistant Coatings for Steel Machining

Steel and alloy steel drilling may require a coating with good wear and heat resistance. The exact option depends on the steel grade and machining conditions.

게다가, harder materials may require a different coating from softer general-purpose steel.

Coating Options for Stainless Steel

When stainless steel is drilled, heat resistance and cutting stability are important. The coating should also help reduce material adhesion around the cutting edge.

하지만, coating selection must be combined with suitable flute geometry and cutting parameters.

Low-Friction Options for Non-Ferrous Materials

Aluminum and copper alloys may benefit from a low-friction coating, polished flute, or uncoated cutting surface.

These options can help reduce built-up edge and improve chip flow. Nevertheless, the final choice depends on the specific alloy and drilling condition.

How a Suitable Coating Is Recommended

To recommend a suitable coating, please provide:

• Workpiece material and grade
• Material hardness
• Required hole diameter
• Hole depth
• Through hole or blind hole
• Machine type
• Coolant condition
• Estimated order quantity

Coating availability also depends on the drill type and order requirements. 그러므로, the final coating will be confirmed during the quotation process.
