GenSwiss Coolant Drill Sleeves
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.
