Abstract
A tool holder includes a body with a central internal threaded section, and a coolant coupling device within the tool holder. The coolant coupling device includes a threaded body section to engage the internal threads of the tool holder, a smaller diameter nose section, and a coolant passage through the device to align with a coolant passage in a cutting tool. A sealing ring around the end of the coolant passage forms a seal when the coolant coupling device abuts against a tool shank. The body section includes a wrench slot by which to turn the device for axial movement within the tool holder.
Claims2
A tool holder including a body with an axial through passage having a central internal threaded section, and a coolant coupling device, said coolant coupling device including:
- a threaded body section to engage said internal threaded section of said tool holder, and a nose section of smaller diameter than said body section;
- said body and nose sections together defining a coolant passage therethrough, said passage including a counterbore at the end thereof in said nose section and a chamfer at the end thereof in said body section;
- a sealing ring disposed in said counterbore;
- and a slot at the base of said chamfer for engagement with a tool to turn said coolant coupling device for axial movement thereof within said tool holder.
A tool holder defining an internally threaded through passage, and including a coolant coupling device within said passage;
- said coolant coupling device defining a coolant passage therethrough and including a threaded body section for threaded engagement within said passage, and a nose section of smaller diameter than said body section;
- said nose section including a sealing ring around one outer end of said coolant passage;
- said body section including a slot for engagement by a tool to turn said body section for axial movement thereof within said tool holder, said coolant passage in said body section having a funnelled opening to guide said tool into said slot.
