Dual Straight Hole Internal Coolant Straight Flute Drill – Customer FAQ

2025-08-08

In deep hole drilling, selecting the right deep hole drill is essential for improving production efficiency, machining quality, and reducing manufacturing costs. The AMG dual straight-hole internal coolant straight flute drill has become a popular choice for manufacturers requiring high precision deep hole machining and efficient chip evacuation. Here we address the most common customer questions about tool life, chip removal, and drilling accuracy.


1. Tool Life – How durable is the drill?
AMG uses premium solid carbide and advanced grinding technology to enhance wear resistance and heat stability. The dual internal coolant channels effectively reduce cutting temperature, extending the tool life and maintaining stable performance during high-speed CNC machining.


2. Chip Evacuation – Is chip removal effective in deep hole drilling?
The drill’s straight flute design combined with dual coolant holes ensures smooth and rapid chip evacuation, preventing chip clogging and tool damage. This is critical when drilling materials like stainless steel, alloy steel, aluminum alloys, and copper alloys.


3. Deep Hole Machining Accuracy – Can it maintain precision at high drilling depths?
With tight manufacturing tolerances and a rigid structure, the drill delivers excellent hole straightness and surface finish for deep holes up to 30 times the diameter. This reduces vibration and improves machining consistency in batch production.


Specifications 

Model Diameter (mm) Overall Length (mm) Flute Length (mm) Shank Diameter (mm) Material Cooling Method
AMG-DR06×D20 6 120 60 6 Solid Carbide Dual Internal Coolant
