HOZLY BT30 ER32-60L CNC Milling Machine Chuck 0.005mm Precision

Decent little tool holders, the collet nut to tool body is close tolerance and is satisfying to thread on/off. Run out is acceptable.They do not come with the retention studs as shown in the photos.For $31, they do the job nicely. Just purchase the correct retention stud for your spindle.

精度が悪いので使えません。使えれば儲けものぐらいの値段でしたので、外れクジを引いたと諦めます、残念でした。
