CTS-7.94-158760: Coolant Thru Drilling & Boring sleeve Ø .3125" ID-Ø.625" Shank-OAL 3.0"-M6-1.00 Scr

GenSwiss® coolant-thru drill and boring sleeves are a new product designed and manufactured by GenSwiss®.  GenSwiss® drill and boring sleeves feature precision ground inch and metric shanks and are a robust method for holding drills and boring bars to tight tolerances.  Each GenSwiss® sleeve features coolant-thru holes, enabling coolant delivery to your coolant-thru drills or boring bars. The absence of an ER collet means each sleeve is sized to the specific tool shank intended for use and therefore removes any errors that can occur with standard ER collet based holders.

Coolant-thru drill and boring sleeves also streamline the number of components needed for tool holding, removing the seals required for coolant-thru ER collets.  Each coolant-thru sleeve is designed with a rear coolant input and mates with a 1/8-28 BSPP coolant fitting. Sleeves are manufactured in several inch and metric shank sizes; 5/8in, 3/4in, 1in, 20mm, and 22mm.  Nominal tool bore sizes range from 3mm to 8mm, however, drill sleeves can be manufactured to custom order.  Two set screws are present along the flats on each sleeve shank, providing a simple yet quick way to secure the tools into place.
