A setting key for attaching a plane iron to a tapering plane at a specific desired tapering angle, the setting key comprising: a first edge shaped to fit into a setting key function slot with an opening along a circumference of a mortise of the tapering plane; and a second edge positioned opposite to the first edge, wherein when the setting key is inserted into the setting key function slot: the first edge is nested in the setting key function slot, and the second edge protrudes into and radially bisects the mortise of the tapering plane, such that the second edge provides a surface spaced from the mortise edge and positioned at an orientation that differs from a mortise longitudinal axis by the specific desired tapering angle to hold the plane iron so that it is configured to be attached to the tapering plane at the specific desired tapering angle.

A cut length indicating device for a portable machine tool includes at least one indication unit. The indication unit has at least one movably mounted indication element that is configured to indicate at least one position of a cutting edge of a machining tool on a work piece to be machined with reference to a set cutting depth of the machining tool. The indication element further has a cutting edge indication line, which runs at least substantially transversely to a movement plane of the indication element in order to indicate the position of the cutting edge in at least one operating state.

A woodworking jig is used to set cutter height and horizontal fence position when forming lock miter joints with a forty-five degree (45) lock miter cutter on a router table or shaper. Vertical and horizontal reference lines are formed on the exterior surface of the jig. Setup is accomplished by adjusting the cutter height and fence position until the appropriate reference lines on the jig align with centerlines or centerline-derived lines on the edge of the stock. Using the appropriate reference lines, the jig is used to complete setups for standard lock miter joints with boards of equal thickness, non-standard lock miters joints with boards of different thicknesses, and offset lock miter joints. The jig has no moving parts, requires no calibration or measuring devices, and works with any lock miter router bit and most shaper cutters. The jig locates the geometric center of the router bit profile with precision.

A hand-held power tool, more particularly a router, includes (i) a housing in which a drive unit for driving an insertion tool is disposed; (ii) a base plate for guiding the hand-held power tool on a workpiece surface, the base plate being height-adjustable on the housing, and the base plate having an opening, through which the insertion tool at least partly extends; and (iii) a height adjustment device for setting a working height of the base plate on the housing relative to the insertion tool. A setting aid is provided which allows height adjustment of a bottom of the base plate by way of the height adjustment device such that said bottom is flush with a predefined cutting edge of the insertion tool.
