Sleeves
Description
The connecting sleeve is mainly used for the shank and the drill
rod and the drill rod and the connecting rod is connected between
the. For reducing the connecting sleeve and the connecting sleeve
with the same diameter. Main specifications R32, T38, T45, T51
reducer connected set of R25-R32, R28-R32, R32-R38, R32-T38,
R32-T45, T38-T45 and, due to the need of energy transfer and
handling, on the material properties and processing technology of
higher requirements, connecting sleeve of my company's production,
the high quality alloy steel forging processing into, the thread
processing the special machining center, high machining precision,
with good thread and prolong the prolonging the service life of the
connecting sleeve.
