Carbide deep hole drill with internal cooling oil hole:
ADO-40D and 50D

Cooling of the engine block is critical in overall engine operation. The deep hole machining of the engine block is a hole machining technology with high processing difficulty, high processing cost and high requirements on tools. It often encounters processing difficulties in cooling, lubrication, chip removal, and tool rigidity. OSG has recently launched the ADO-40D and 50D carbide deep hole drills with internal cooling oil holes that can achieve ultra-high processing efficiency in deep hole drilling applications.
1. Product features:
picture
ADO-40D and 50D have a unique R-shaped crescent groove, which can achieve ultra-low cutting resistance and stable chip removal efficiency. In the application of deep hole processing, it can break the chip finely, and the chip shape is tightly curled, without deformation and stretching, and realizes unobstructed chip removal.

The new groove pattern balances smooth chip removal efficiency and tool rigidity in deep hole machining applications.
ADO-40D&50D adopts 25°helix angle which is most suitable for ultra-deep hole machining. After OSG test, it is found that the most stable processing can be achieved when the helix angle is 25°. If a smaller helix angle of 20° is used, the chips are easily blocked, and the tool breaks due to chip problems. If a larger helix angle of 30° is used, the rigidity of the tool will deteriorate and the machining will be unstable.

The surface of the tool adopts OSG's self-developed EgiAs coating, which has high toughness, high wear resistance, and high heat resistance, achieving stable and long tool life.

3. Difficulties in workpiece processing
Large end ring groove and outer round end of the turbine shell: the processing position is shown in the red area in Figure 2. The accuracy of the processing position should be within ±0.1mm, the surface quality should be Ra3.2, the workpiece material is a heat-resistant alloy, and the processing process is forming In machining, the cutting tool bears a large cutting force, is easy to wear, and is prone to tool vibration, so the blade is required to be held firmly.
