Instructions of carbide end mill

1. Before using the carbide end mill, please measure the tool deflection. If the tool deflection accuracy exceeds 0.01mm, please correct it before cutting.

2. The shorter the carbide extends out of the collet, the better. If the tool extends out longer, reduce the speed, feed speed or cutting amount.

3. In case of abnormal vibration or sound during cutting, please reduce the speed and cutting amount until the situation is improved.

4. Spray type and air jet type are preferred for steel cooling, which can improve the use effect of carbide end mill.

5. Note: Not suitable for low speed machines such as rotary table and electric hand drill.
