    摘要： Tool elements and methods. In some constructions and in some aspects, a tool element includes a main body and an indicator positioned on the main body for indicating the position of the tool element relative to a workpiece. In some constructions and in some aspects, a tool element is useable with a power tool, which has a guide. The tool element includes a main body connectable to the power tool and an indicator positioned on the main body for indicating the position of the guide relative to the workpiece. In some constructions and in some aspects, a method of manufacturing a tool element includes providing the tool element and producing an indicator on the tool element for indicating the position of the tool element relative to a workpiece.

    摘要： A drill cutting insert has a cutting edge at a transition between a side surface and a top side which is formed with n identical cutting corners and n identical partial cutting edges —with nε{3, 4} —extending between the cutting corners. Each of the n partial cutting edges has: adjoining a first cutting corner, a main lip which is straight in plan view of the top side; adjoining the other cutting corner, a secondary lip which is straight in plain view of the top side, and a transition section, via which the main lip and the secondary lip merge into one another and which has a convex section adjoining the main lip and a concave section adjoining the secondary lip. The main and secondary lips enclose on the outside an angle a α

    摘要： A protection tool for an electronic drill provides various functions when drilling is carried out. The electronic drill has a front end with a through hole located at the front end and a drill head extending through out the through hole. The protection tool is moveably mounted at the front end of the electronic drill along an operation direction. A guard plate includes a pore aligning with the through hole and provides pass way for the drill head. A supporting frame is assembled with the guard plate and is moveably mounted at the front end of the electronic drill along the operation direction, so that the guard plate is positioned at a variable distance from the front end according to the movement of the supporting frame with respect to the front end.
