Abstract
The invention relates to a modular rotary tool, which extends along an axis of rotation (6) in the longitudinal direction and which has a carrier provided with flutes as well as a cutting head exchangeably secured on said carrier, wherein the carrier has on the end surface a coupling receiving means for receiving a coupling pin of the cutting head, wherein in the carrier, a coolant channel is formed, which terminates at a first outlet opening in the coupling receiving means, and wherein a branch channel is provided, which is spaced apart from the coupling receiving means and which opens into the coolant channel at one end and terminates at a second outlet opening in the flute at the other end.
Claims13
A modular rotary tool, which extends along an axis of rotation in the longitudinal direction, said modular rotary tool comprising:
- a carrier which includes flutes, and
- a cutting head which is exchangeably secured on the carrier and includes a coupling pin,
- wherein the carrier comprises an end surface and, disposed at the end surface, a coupling receiving means for receiving the coupling pin of the cutting head,
- wherein the carrier further includes:
- a coolant channel formed therein, the coolant channel terminating at a first outlet opening disposed in the coupling receiving means, and
- a branch channel spaced apart from the coupling receiving means,
- wherein the branch channel, at one end thereof, opens into the coolant channel and, at another end thereof, terminates at a second outlet opening disposed in one of the flutes, and
- wherein the second outlet opening permits a flow of coolant/lubricant toward a cutting edge of the secured cutting head if the first outlet opening is blocked by the secured cutting head.
A modular tool system comprising:
- a plurality of cutting heads, and
- a carrier which includes flutes,
- wherein each of the cutting heads:
- is exchangeably securable on the carrier, and
- includes a coupling pin,
- wherein the carrier comprises an end surface and, disposed at the end surface, a coupling receiving means for receiving the coupling pin of each of the cutting heads,
- wherein the carrier further includes:
- a coolant channel formed therein, the coolant channel terminating at a first outlet opening disposed in the coupling receiving means, and
- a branch channel spaced apart from the coupling receiving means,
- wherein the branch channel, at one end thereof, opens into the coolant channel and, at another end thereof, terminates at a second outlet opening disposed in one of the flutes, and
- wherein the second outlet opening permits a flow of coolant/lubricant toward a cutting edge of a secured one of the cutting heads if the first outlet opening is blocked by the secured one of the cutting heads.
