An electric power tool is disclosed. In an embodiment, the electric power tool includes a tool, a tool holder part and a main body with a plurality of rivets integrated with the main body. The rivets include rivet shafts of a cross section for producing a positive-locking rivet joint of the tool with the tool holder part, wherein the tool and the tool holder part have circular openings which are aligned with each other, and wherein the rivet shafts are positioned aligned with the openings on the main body and protrude through the aligned openings.

A laminar is formed from a plurality of sections, where in one example, one or more of the sections are selected to have a configuration according to a known parameter or characteristic of the section, for example material characteristics. One or more sections are cut from a raw material or stock material according to the known parameter or characteristic, which for example can be a known characteristic of the stock material such as roll direction.

A tip saw has a disc-shape and comprises cutting blade pieces and a base metal. The cutting blade pieces are disposed on blade edges of the tip saw, and each of the cutting blade pieces extends to a reverse rotation side of the each of the cutting blade pieces along an outer side of the tip saw. Two of the cutting blade pieces adjacent to each other partially overlap in a circumferential direction along the outer side of the tip saw. The each of the cutting blade pieces has a cutting edge portion on a rotation side of the each of the cutting blade pieces and a support portion on the reverse rotation side of the each of the cutting blade pieces.

A blade assembly is formed from multiple blades assembled adjacent each other with openings in respective blades arranged to form a passageway passing through adjacent blades.

Stabilized cutting tool assemblies. A cutting tool assembly for use with a reference surface includes a tool holder having a rotational axis. The tool holder is arranged for attachment to a drive source arranged to rotate the tool holder and move the tool holder relative to a reference surface. The cutting tool assembly includes a rotatable cutting tool coupled to the tool holder. The cutting tool includes a cutting surface and has a first portion and a second portion. The first portion is disposed adjacent the tool holder. The cutting tool assembly includes a stabilizer coupled to the cutting tool adjacent the second portion. The stabilizer has a bearing surface. The bearing surface is positioned on the second portion to abut the reference surface and to stabilize the cutting tool when the drive source moves the tool holder and the cutting tool to a position adjacent the reference surface.

A circular saw blade has a substantially circular core zone which is surrounded by an edge zone adjoining the core zone radially outwards in the region of a boundary line in order to form a basic body. The edge zone has a plurality of teeth, each with a tooth face, and each tooth face is assigned a carbide tip. A tooth space is in each case formed between two teeth directly adjacent circumferentially, and a friction-reducing sliding coating and a wear-reducing hard coating are provided which are formed lying one above the other at least in certain regions.
