FIELD: machine building.
SUBSTANCE: cartridge for tool holder (60) of the tool for making grooves extending along the plane in the middle of the thickness by limiting peripheral surfaces (20), which comprise: clamping surface (28); back surface (26) for fixation of the tool to holder (60) along screwing direction (44), front surface (24). In this case, the cartridge contains channel (30) for coolant extending along direction (34) from rear surface (26) to front surface (24). Screwing direction (44) and direction (34) of the extension of coolant channel (30) are contained in the plane in the middle of the thickness of cartridge (20). Said tool holder comprises upper front surface (62) for attachment, by screwing onto rear surface (60) of cartridge (20).
EFFECT: improved coolant supply is achieved when deep grooves are made.
