摘要： A combination-type machining tool has a handle segment and a head segment. The handle segment is made of stainless steel or carbon steel and has a clamping handle and a body. The body is axially formed on and protrudes from a front end of the clamping handle and has a protruding rod axially formed on and protruding from a front side of the body. The head segment is made of tungsten steel, is mounted around the protruding rod and has a through hole axially formed through a front side and a rear side of the head segment, and an inner peripheral surface of the through hole is securely mounted around the protruding rod to enable the rear side of the head-segment to abut against the front side of the body.
