Modular carrier tool and tool head

A tool head for reversible fastening in a carrier for a carrier tool, the tool head extending in an axial direction along a central longitudinal axis, the tool head comprising:

• clamping surfaces extending in an axial direction;
• underhead bearing surfaces extending in an axial direction, via which the tool head sits on bearing surfaces of the carrier in a mounted state;
• flute sections;
• and
• torque transmission surfaces which:
• extend radially to an outer periphery of the tool head;
• and
• extend axially from the underhead bearing surfaces toward a front of the tool head;
• wherein, along a peripheral direction of the tool head, each of the underhead bearing surfaces extends between one of the torque transmission surfaces and one of the flute sections;
• wherein the underhead bearing surfaces are tilted at a tilt angle defined along a radial direction with respect to the central longitudinal axis.

A modular carrier tool comprising:

• a carrier for accommodating a tool head, the carrier comprising bearing surfaces extending along a radial direction with respect to a central longitudinal axis of the modular carrier tool;
• and
• a tool head comprising:
• underhead bearing surfaces which engage with the bearing surfaces of the carrier, when the tool head is accommodated in the carrier;
• flute sections;
• and
• torque transmission surfaces which:
• extend radially to an outer periphery of the tool head;
• and
• extend axially from the underhead bearing surfaces toward a front of the tool head;
• wherein, along a peripheral direction of the tool head, each of the underhead bearing surfaces extends between one of the torque transmission surfaces and one of the flute sections;
• wherein the bearing surfaces of the carrier and the underhead bearing surfaces are tilted at a tilt angle defined along a radial direction with respect to the central longitudinal axis.
