Introduction of Gun Drills
A gun drill, also known as a deep hole drill, is a specialized tool designed for high-precision drilling, capable of producing deep holes with a diameter-to-length ratio of up to 1:250. The gun drill consists of three main components: the drill head, drill shaft, and drill shank, all of which are brazed together. The tool is characterized by a V-shped flute for external chip evacuation, a critical feature that ensures the efficient removal of chips during deep hole drilling.
Carbide Gun Drill
·Structure: Composed of a carbide drill head brazed to a steel shank.
·Advantages: Carbide gun drills are the most common, offering a balance between cost and performance. They are known for their durability and are suitable for a wide range of materials.
·Applications: Ideal for general-purpose deep hole drilling in materials like cast iron, aluminum, and steel.

Benefits of Using Gun Drills
Gun drills offer numerous advantages over conventional drilling methods, particularly in deep hole drilling scenarios.
1. Precision and Accuracy
-
Gun drills are designed to produce holes with exceptional accuracy, meeting tight tolerances and ensuring consistent results.
2. Efficient Chip Evacuation
-
The V-shaped flute design allows for efficient external chip evacuation, preventing blockages and reducing the risk of tool failure.
3. Extended Tool Life
-
High-quality materials and advanced manufacturing processes extend the life of gun drills, reducing the need for frequent replacements.
4. Versatility
-
Suitable for a wide range of materials and applications, from soft metals like aluminum to hard alloys used in aerospace.
Product Feature
Compare to carbide drill
1. Better chip breaking effect, achieve good chip removal.
2. Ensure good hole straightness and surface roughness.
3. Insert replaceable, reduce cost.
4. Without tools regrinding, reduce management costs.
