【Product Introduction】
The AMG solid carbide coolant-through straight flute drill is specifically designed for deep and blind hole machining in machinery structural parts. Manufactured using high-quality ultra-fine grain solid carbide (HM) with precision grinding, it offers high hardness, excellent wear resistance, and superior anti-chipping performance to ensure stability and high hole accuracy during processing. Its internal coolant channel design delivers high-pressure coolant directly to the cutting zone, ensuring rapid heat dissipation, reducing cutting temperatures, improving chip evacuation, extending tool life, and enabling efficient, stable deep hole drilling for structural components.

【Applications】
Ideal for deep and blind hole machining in machinery structural parts such as shafts, jigs, hydraulic cylinder holes, and mold cooling channels. Suitable for high-precision, high-surface-finish deep hole drilling in carbon steel, alloy steel, stainless steel, aluminum alloys, and copper alloys.

Customer purchase guide

When purchasing an internally cooled straight flute drill, we recommend to make your selection based on the following points:

1. Drilling depth: If the hole depth exceeds 6 times the diameter, it is recommended to choose long-edge designs such as 10D, 15D, 20D, and so on , to ensure smooth chip evacuation.

2. Processing materials: For processing stainless steel and carbon steel, TiAlN coating is optional, providing wear resistance and high temperature resistance; for processing soft metals such as aluminum alloy and copper, DLC or no coating is optional to prevent sticking to the tool.

3. Machine tool conditions: Confirm that the equipment has an internal cooling function, and ensure sufficient coolant pressure the temperature reduction and chip removal.

【FAQ】
Q: What materials are suitable for the AMG solid carbide coolant-through straight flute drill?
A: It is suitable for deep and blind hole machining in carbon steel, alloy steel, stainless steel, aluminum alloys, and copper alloys in structural components.
Q: What should customers consider when selecting the drill?
A: Selection should consider hole diameter, depth, material, and coolant pressure. Choose appropriate cutting lengths (such as 6D, 10D, 15D, 20D) and coatings (TiAlN for stainless steel and hard materials, DLC or uncoated for aluminum and soft materials).
