    Abstract: The rotary tool, in particular, the drill (2), extends along a longitudinal axis (4) and has a front surface (6), a center (12), at least two main cutting edges (8), each extending outward from the center (12) to a cutting edge (10), as well as coiled flutes (20). Between the main cutting edge (8) and the flute (20), a common ground surface (26) is also applied, which extends from the center (12) to a radial exterior area in the region of the main cutting edge (8) to form a point thinning (28). A rake angle (γ) is defined by the ground surface (26). Here, the rake angle (γ) changes without steps in the direction of the center (12) and, in particular, continuously. Expediently, the ground surface extends (26) continuously to the cutting edge (10). As a result, on the whole, an advantageous cutting force distribution is achieved over the radial length of the main cutting edge (8).

    Abstract: The mounting wrench (2) is used to engage or disengage a tool head (24) of a modular tool. The mounting wrench (2) incorporates a base body (4), which extends from an upper surface (20) along a centered longitudinal axis (18) to an underside (22). In addition, it has a slotted part (6), extending in the direction of the centered longitudinal axis (18), with a slot (10), into which the tool head (24) can be inserted. The slotted part (6) has two opposing keys (14), extending radially inward, which are each designed to mesh into a keyway (30) of the tool head (24). The keys (14) have a rounded end face (32), oriented radially inward, and are sloped relative to the centered longitudinal axis (18) so that the distance (a) between the keys (14) increases in the direction of the centered longitudinal axis (18).
