Recommended Cutting Data

[Notes]

1. Please use a machine with relatively high rigidity. It is recommended to adopt hydraulic tool holders, thermal expansion tool holders and

powerful handles with spring collets.

2. When installing the tool, it is necessary to ensure that the radial bounce of the drill bit tip is less than 0.02mm.

3. This standard cutting condition table is suitable for water-soluble cutting fluids

4. For the tool edge diameter specifications not listed in the table, please refer to the closest edge diameter specifications in the table to

select the cutting data. Meanwhile, during the machining process, please adjust the cutting data appropriately according to the actual machining situation.

1. Please use a machine with relatively high rigidity. It is recommended to adopt hydraulic tool holders, thermal expansion tool holders and

powerful handles with spring collets.

2. When installing the tool, it is necessary to ensure that the radial bounce of the drill bit tip is less than 0.02mm.

3. This standard cutting condition table is suitable for water-soluble cutting fluids

4. For the tool edge diameter specifications not listed in the table, please refer to the closest edge diameter specifications in the table to

select the cutting data. Meanwhile, during the machining process, please adjust the cutting data appropriately according to the actual

machining situation.

1. Please use a machine with relatively high rigidity. It is recommended to adopt hydraulic tool holders, thermal expansion tool holders and powerful

handles with spring collets.

2. When installing the tool, it is necessary to ensure that the radial bounce of the drill bit tip is less than 0.02mm.

3. This standard cutting condition table is suitable for water-soluble cutting fluids

4. For the tool edge diameter specifications not listed in the table, please refer to the closest edge diameter specifications in the table to select the

cutting data. Meanwhile, during the machining process, please adjust the cutting data appropriately according to the actual machining situation.

[ Notes]

1. Please use a machine with relatively high rigidity. It is recommended to adopt hydraulic tool holders, thermal expansion tool holders and powerful

handles with spring collets.

2. When installing the tool, it is necessary to ensure that the radial bounce of the drill bit tip is less than 0.02mm.

3. This standard cutting condition table is suitable for water-soluble cutting fluids

4. For the tool edge diameter specifications not listed in the table, please refer to the closest edge diameter specifications in the table to select the

cutting data. Meanwhile, during the machining process, please adjust the cutting data appropriately according to the actual machining situation.
