Features and Specifications
The NF-GDN carbide drill is designed for high-efficiency drilling of non-ferrous metals, offering a high precision drill diameter tolerance of 0 to -0.010mm. It supports a super high feed rate of 3,500mm/min and can achieve a feed rate of over 6,000mm/min due to its robust body design. The drill is particularly effective on diecast aluminum, allowing a high feed rate of 10%×D mm/rev.

Machining Data
The NF-GDN drill can operate at various speeds and feed rates depending on the material and conditions. For example, on aluminum alloy A5052, it can achieve a drilling speed of 60m/min with a feed rate of 0.24mm/rev, resulting in a feed speed of 764mm/min. The drill's design ensures chip disintegration and strong lip strength, enhancing its performance.

Dimensions and Stock
The document lists various drill sizes, lengths, and stock availability, indicating a wide range of options for different drilling needs. The drills are made from micro grain carbide and feature S-Thinning for improved performance.

Recommended Drilling Conditions
For optimal performance, the use of water-soluble oil with a dilution ratio of 20-30 times is recommended. The document provides specific drilling speeds and feed rates for different materials, such as aluminum alloy castings and copper alloys.

Safety and Usage Recommendations
Users are advised to wear protective gear and handle chips carefully due to their heat. The document also emphasizes the importance of using clean collets and maintaining drill runout below 0.01mm.

Coating Information
Various coatings are available for the NF-GDN drill, including DLC and FX (TiALN) coatings, which can enhance performance but may slightly increase the drill diameter.
