A suction-extraction adapter for a drilling tool has a housing and a tool connection unit. The housing has a suction-extraction device interface for the detachable connection of a suction-extraction device to the suction-extraction adapter. The tool connection unit enables the axial fixing of the suction-extraction adapter on the drilling tool. The housing also has a locking mechanism. The tool connection unit is configured to be locked on the housing of the suction-extraction adapter via the locking mechanism.

Suction-extraction adapter

A suction adapter for a drilling tool with a conduit includes a housing, at least one air intake port, and a valve unit. The valve unit is configured to open the air intake port as a function of a flow parameter.

Suction adapter

A drilling tool, in particular a rock drilling tool, for a portable machine tool, includes an axis of rotation, at least one spiral path, and at least one wear surface transition. The at least one spiral path is coiled about the axis of rotation along the axis of rotation and includes at least one wear surface having at least one bandwidth. There is a change in the at least one bandwidth of the at least one wear surface at a position of the at least one wear surface transition.

Drilling tool

The invention relates to a drilling tool, especially for percussion drilling, which comprises a cutting element () that is configured as a plate () or head and that has at least one cutting edge () defined by a cutting face () and a free face (). The cutting edge () is associated with a first free face section () which is limited in a cutting plane at a right angle to the cutting edge () and parallel to the longitudinal axis (L) of the drilling tool () by a convex bulge () or a convex polygon outline. The vertical height of a rib () defined by the first free face section () and an associated first cutting face section () ranges from 0.1 mm to 1.0 mm.

Drilling tool with a cutting element that is configured as a plate or head

A drilling and/or chiseling tool, in particular for machining materials such as concrete, rock, masonry, and the like, having a hard metal cutting element () contained in the machining end of the tool head, a radially outer, second working region (II) of the hard metal cutting element () being set back in relation to a central, first working region (I) of the hard metal cutting element () and the two working regions (I, II) transitioning into each other via a third working region (III). The third working region (III) is at least partially comprised of at least one partial circumference surface () of at least one conical surface.

Drilling and/or chiseling tool

The invention relates to a drilling tool (), in particular for working concrete, rock, masonry and suchlike materials, having a single- or multi-edge tool head with at least one cutting body () which comprises a central region () which is designed in a roof shape, has rake faces and flanks and is defined laterally by two outer regions () set back in the effective direction of the drill. In this case, the ground surfaces of the central region () form a pyramidal point () while avoiding the formation of a chisel edge.

The invention relates to a drilling tool (), in particular for working concrete, rock, masonry and suchlike materials, having a tool head with cutting body () which has at least one front rake face (), at least one rear flank ([lacuna]) and at least one front-end cutting edge (), the cutting edge () separating the rake face () and the flank ([lacuna]). In this case, the rake face () is formed by at least two cutting faces ([lacuna]) merging into one another at at least one second cutting edge ().
