*When you order please indicate the hilt the concrete form.

1.Amodel:Without through hole.

2.ADmodel:With through hole for center coolant.

3.AD/Bmodel:Form AD and farm B, the former is in the center cold. the latter is in the flange plate cold. may realize central cooling and the side cools two forms the freedoms to transform.

*According to needs to be possible to provide the balanced hilt. the standard precision is G6.3/12000rpm, the precise precision is G2.5/20000rpm.
