FIELD: hand tools.
SUBSTANCE: invention relates to auxiliary devices used when working with a hand-held mechanized tool, and can be used for drilling holes in angular joints of elements of building structures, for example, for laying cable lines, using a hand-held mechanized tool. Jig for drilling holes in corners comprises a base with a slot and a carriage moving along it. Base is made in form of 1/8 of sphere with concentric inner spherical cavity, which is conjugated with external spherical surface of carriage, having radius slots on side surfaces for movement in angular sector along vertical plane of base bushing, with replaceable centring bushing installed in it. All radii of spherical surfaces and slots have a single starting point.
EFFECT: possibility of adjustment of angles of rotation axis of cutting tool without displacement from initial point of drilling.
