A power tool for forming a channel in a work surface includes a first section carrying a rotatable shaft having a shaft axis and a second section that engages the work surface; a cutting disc having a substantially circular blade provided on the rotatable shaft; a first support portion on one side of the cutting disc and a second support portion on the opposite side of the cutting disc which cooperate to hold the cutting disc at an oblique angle relative to the shaft axis. A first locking feature of the first support portion and a second locking feature of the second support portion extend through a circular opening of the cutting disc and cooperate to resist relative rotation of the first and second support portions. The first section is movable relative to the second section to move the cutting disc into and out of engagement with the work surface.

A rotating cutting assembly includes a wheel and a tooth base coupled to an outer periphery of the wheel. The tooth base includes a narrowed stem and an aperture spaced from the narrowed stem. The cutting assembly further includes a cutting tooth removably secured to the tooth base. The cutting tooth has a mounting surface configured to engage the tooth base, and first and second bosses extending from the mounting surface and spaced apart from one another by a distance at least as large as a width of the narrowed stem such that the first and second bosses straddle the stem when the mounting surface engages the tooth base. The cutting tooth further includes an aperture aligned with the aperture in the tooth base. A fastener is received in the aperture of the cutting tooth and the aperture of the base to removably secure the cutting tooth to the base.

A land preparation tool includes a tool body having a cutting surface, mounting surfaces disposed on the tool body opposite the cutting surface, and opposing side surfaces each extending between the cutting surface and a different one of the mounting surfaces. One mounting surface angles inwardly from a distal edge of a side surface toward the tool body.

One tool mounting surface extends outwardly from the apex at an angle toward the cutting surface. Another tool mounting surface extends outwardly from the apex, opposite the other tool mounting surface, at an angle toward the cutting surface. Other embodiments are described and claimed.

A method for producing a machining segment from a first powdered matrix material and first hard material particles arranged according to a defined first particle pattern, includes: applying a powdered supporting material as a supporting layer with a melting temperature higher than the first matrix material, arranging the first hard material particles according to the defined first particle pattern in the supporting material with a depth of penetration, applying a first layer of the first matrix material to the first hard material particles and the supporting material and fusing the first layer by a powder bed fusion method, and performing a sequence of a plurality of steps N times, N1, wherein, in a first step of the sequence, a layer of the first matrix material is applied to the layer structure, and in a second step of the sequence, the layer of the first matrix material is fused by the powder bed fusion method and connected to the layer structure.

A land preparation tool includes a tool body having a cutting surface, a mounting surface, an opening, and a channel. The cutting surface has a blade positioned at a distal end thereof. The mounting surface has a non-planar profile and is disposed on the tool body opposite the cutting surface. The opening is disposed on the mounting surface and the channel extends from the opening at least partially into the tool body. Other embodiments are described and claimed.

An abrasive segment can include an inner segment portion, an outer segment portion, and a central segment portion connected thereto. The inner segment portion can include an inner circumferential wall and an outer circumferential wall. Leading and trailing radial sidewalls can extend between the inner circumferential wall and the outer circumferential wall opposite each other. The outer segment portion can include an inner circumferential wall and an outer circumferential wall. Leading and trailing radial sidewalls can extend between the inner circumferential wall and the outer circumferential wall opposite each other. The central segment portion can include a leading radial sidewall and a trailing radial sidewall. The leading radial sidewall of the central segment portion can establish an acute angle, , with respect to the outer circumferential wall of the inner segment portion and an obtuse angle, , with respect the inner circumferential wall of the outer segment portion.
