FIELD: machine building.
SUBSTANCE: invention refers to machine building, particularly to connecting tools such as boring cutters and heads, drills, end reamers and end-milling cutters to holders. The tool connector consists of enveloped and enveloping parts each restricted with corresponding basing coaxial conic and cylinder surfaces. Diametre of cylinder surface is less, than the smallest diametre of conic surface, apex of which faces cylinder surface. Stepped conjugated threaded sections with continuous thread are made on enveloped and enveloping parts between conic and cylinder surfaces. The threaded sections are made along lengthwise axis with equal length. Diametre of threaded sections diminishes from conic to cylinder surface.
EFFECT: raised reliability of connection.
