A tool unit includes a tool head, a motor and a switching drive for the head. The head has a first section with first blades and a second section with second blades. The second section is movable to and fro between a passive and an active position relative to the first section, the second blades being retracted in the passive position, and the second blades projecting axially beyond the first blades in the active position. The drive includes an electromagnet and an actuating armature made from magnetically attractable material and is arranged in the region of action of the electromagnet. The electromagnet is positioned between the head and the motor and is fastened to a housing part of the motor such that it cannot be rotated. The armature is connected fixedly to the second section. A gap remains between the electromagnet and the armature in the passive and active position.

Saw blades and methods of machining saw blade tooth profiles of saw blades. The saw blades include a blade body and a plurality of teeth defined by the blade body. Each tooth includes a tooth back, a tooth tip, a tooth face, and a tooth gullet. In at least one tooth, a relief region extends toward the tooth back and separates the tooth face from the tooth gullet. The methods include supporting the saw blade with a blade support structure and advancing the saw blade with a blade advance structure. The methods also include dry-machining a finished tooth profile in a working portion of the saw blade in a single pass. The dry-machining includes dry-machining with an end mill by operatively translating the end mill relative to the saw blade and within a plane that is at least substantially perpendicular to an end mill rotational axis of the end mill.

A disposable chamfering blade is provided with a mounting hole through which the disposable chamfering blade can be locked to a cutter body. One end of the disposable chamfering blade is provided with a conical cutter head whose conical periphery is circumferentially provided with a plurality of chip removing grooves. Each chip removing groove has a side face formed as a cutting edge such that the disposable chamfering blade is formed with a plurality of cutting edges for continuous cutting.

A method of chamfering an aperture in a reel member of a tensioning system for an article of footwear is disclosed. The tensioning system includes a reel member configured to rotate about a central axis. The reel member includes a shaft and at least one flange disposed along the shaft. The flange includes an aperture extending through the flange. The aperture is configured to receive a lace. The reel member can tighten the tensioning system by winding the lace around portions of the shaft disposed on both sides of the at least one flange. The method of chamfering the aperture includes drilling through an end flange of the reel member to reach the center flange of the reel member in order to chamfer the aperture. The chamfered aperture can assist with sliding the lace through the aperture and distributing tension.
