초록 ▼

A hand-held power tool with a circular-disk-shaped tool mounted on an output shaft which extends normal to a drive shaft has a guiding part which surrounds the tool in an immovable position at its cutting side. The guiding part has a wall arranged for abutting against a workpiece and having a through slot for the tool, and a guiding edge extending parallel to a cutting direction of the tool, and the guiding part being movably guided in direction normal to the wall.

대표청구항 ▼

1. A hand-held power tool, comprising a drive shaft; an output shaft extending angularly to said drive shaft; a circular-disk-shaped cutting tool element mounted on said output shaft and having an axis; and a guiding part surrounding said tool element in its immovable position at its cutting side, said guiding part having a wall arranged for abutting against a workpiece and having a through slot for said tool element, and a guiding edge which is formed as a further wall extending parallel to a cutting plane of said tool element and upwardly beyond said first-mentioned wall in direction away from a workpiece, said guiding part being movable guided in a direction normal to said wall and normal to said axis of said tool element. 2. A hand-held power tool as defined in claim 1, wherein the hand-held power tool is an angular power tool, said circular-disk-shaped tool element being formed as a circular saw blade mounted on said output shaft. 3. A hand-held power tool as defined in claim 2, wherein said circular saw blade has a part facing away from the workpiece; and further comprising a protective housing which surrounds said part of said circular saw blade, and means for connecting said guiding part with said protective housing. 4. A hand-held power tool as defined in claim 3, wherein said connecting means includes two guiding openings provided in said protective housing, two guiding pins mounted with their one ends in said guiding part, two pressure springs received by said guiding pins between said guiding part and said protective housing, and securing members arranged on said guiding pins at their ends extending outwardly beyond said guiding openings for securing said guiding pins against withdrawl from said guiding openings. 5. A hand-held power tool as defined in claim 2, wherein said guiding part and said protective housing form two elements; and further comprising a power tool housing having an abutment surface, and an adjustable abutment provided in one of said elements and directed towards said abutment surface, so as to adjust said guiding part and therefore an insertion depth of said circular saw blade into the workpiece. 6. A hand-held power tool as defined in claim 1, wherein said guiding part has at least lateral wall extending parallel to a guiding direction of said guiding part. 7. A hand-held power tool as defined in claim 2, wherein said guiding part has a foot plate which is provided with at least one abutment edge extending parallel to said circular saw blade and having an adjustable distance from said circular saw blade. 8. A hand-held power tool as defined in claim 1, wherein said protective housing has an auxiliary handle. 9. A hand-held power tool as defined in claim 2, wherein said protective housing forms together with said guiding part an auxiliary unit for clamping on the angular grinder. 10. A hand-held power tool as defined in claim 9, wherein the angular grinder has a clamping collar; said auxiliary unit formed by said protective housing and said guiding part being mountable on said clamping collar of the angular grinder. 11. A hand-held power tool, comprising a drive shaft; an output shaft extending angularly to said drive shaft; circular-disk-shaped cutting tool element mounted on said output shaft and having a part facing away from a workpiece; a protective housing which surrounds said part of said circular-disk-shaped tool element; and a guiding part surrounding in an immovable position said tool element at its cutting side, said guiding part having a wall arranged for abutting against a workpiece and having a through slot for said tool element, and a guiding edge extending parallel to a cutting direction of said tool element, said guiding part being movable guided in a direction normal to said wall, said guiding part having at least one lateral wall extending parallel to a guiding direction of said guiding part and arranged so that during penetration of the circular disc-shaped tool element into the workpiece it is inserted into the interior of said protective housing together with said circular disc-shaped tool element.
