AMG Solid Carbide Internal Cooling Straight Flute Drill - The Professional Choice for Deep Hole Drilling of Structural Components

When machining structural components, deep hole drilling is an operation with high technical difficulty and high stability requirements. AMG has specifically developed this internally cooled straight flute drill for such machining.

Made of high-quality ultra-fine grain cemented carbide and ground by high-precision equipment, it is high hardness, wear resistance, and resistance to chipping, making it suitable for long-term high-speed drilling.

The internal cooling design allows the cooling fluid to flow directly to the tool tip, significantly reducing the high temperature issues during drilling. At the same time, it can quickly flush away the chips, preventing blockages and tool jams, making deep hole machining smoother and safer.

Applications
Suitable for deep hole and blind hole drilling of structural components, including mechanical structures, mold deep cooling channels, and fixture deep holes. It meets the high-precision and high-surface-finish deep hole machining requirements of carbon steel, stainless steel, aluminum alloys, copper alloys, and other metal structural components.

【Customer Selection Guide】
When selecting a solid carbide coolant-through straight flute drill, customers should choose the appropriate specifications based on the material (such as stainless steel, carbon steel, copper alloys, etc.), hole depth, hole diameter, and machine coolant pressure.

1. For deep holes exceeding 10 times the diameter, it is recommended to choose a longer cutting length design to ensure smooth chip evacuation.
2. When machining high-hardness or stainless steel materials, we recommend to select TiAlN coating to enhance wear resistance.
3. When machining aluminum alloys or materials prone to adhesion, customer select a DLC coating or an uncoated option to reduce the risk of chip sticking.
