The injection direction forms one angle with the fixed direction, but the fixed direction uses the close fit for a mount and is applied to each CNC system.

1. Easy adjustable angle.
2. Accurate and steady positioning, with no spring-back.
3. Get the "water" power ready for an accurate injection towards milling cutter or drill, thus securing the sufficient cooling for cutter or drill during the machining process and extending its service life.
4. Applied widely to the spraying and cooling system and ejector of each type of machine.
