Sandhog Threading Insert Thread Cutting Tool Holder External Threading Holder

Product Description

1. Can be used on cnc lathe machine and engine lathe .

2. Matched with CNC inserts with hole .

3. Spare part made of high quality steel , the hardness of screw is grade 12.9

4. Material carbide and whole forging processing make the turning tool with long service life, better wear-resistantce,strength and rigidity,high working efficiency.

5. Using 0.02mm feeler gauge to insure the tightly connection between the inserts and the tool.

6. Processed with high precision CNC machining centre.


The main requirements for thread turning tools are as follows:

(1) The sharp angle of the turning tool must be equal to the tooth angle of the thread;

(2) The longitudinal rake angle of the turning tool during precision turning should be equal to 0 °; When rough turning, a longitudinal front angle of 5 ° -15 ° is allowed;

(3) Due to the influence of thread rising angle, the static back angle on both sides of the turning tool should not be equal, and the back angle behind the feed direction is relatively large. Generally, it should be ensured that both sides have a working back angle of 3 ° -5 °;

(4) The straightness of the cutting edges on both sides of the turning tool is good.

There are two materials for manufacturing thread turning tools: high-speed steel and hard alloy. The high-speed steel thread turning tool has convenient grinding, sharp cutting edges, good toughness, and can withstand large cutting impact forces. The surface roughness of the processed thread is small. But its heat resistance is poor and it is not suitable for high-speed turning.

Hard alloy thread turning tools have high hardness, good wear resistance, and high temperature resistance, but poor impact resistance. CNC lathes generally use hard alloy indexable turning tools.
