KS KABUTO SEAL CENTER
Structured to keep cutting water away by means of oil seal.
The waterproofing function still works under slower rotation.
The replacement head enables cost reduction.

- See page HEAD LIST for center head types.
- See page ALLOWABLE LOAD & MORSE TAPAR for revolutions per minute.
- The difference between types S and P is their waggle accuracy.
- We recommend that type KFL be used for fine machining or light metal working.
- Types S and P have the same dimensions.
- Type KS comes with the center head A and then the center head ejecting drift DHN-1
(KS-5S and P come with the center head 5A60° and DHN-2).
