Tangless helically coiled insert installation system

An installation tool adapted to install tangless, helically coiled, inserts into a tapped hole, the installation tool comprising:

• a tubular body extending along an insertion axis, the tubular body including a first end portion and an opposite second end portion, wherein the tubular body includes an internal surface defining a through-bore centered to the insertion axis and communicating through the first and second end portions, and a direction of insert travel is from the first end portion and through the second end portion along the insertion axis;
• an insert exit port defined by the internal surface at the second end portion, centered about the insertion axis, and in communication with the through-bore, wherein the through-bore includes a bore diameter that is larger than a port diameter of the insert exit port;
• an insert entry port defined by the first end portion and in communication with the through-bore;
• a mandrel including a drive attachment end segment and an opposite threaded end segment, the mandrel including a staging position wherein the threaded end segment is axially displaced out of the tubular body enabling receipt of the tangless helically coiled insert through the insert entry port and into the through-bore, and a staged position wherein the tangless helically coiled insert is threaded upon the threaded end segment and is radially contracted via biased contact against the internal surface at the insert exit port;
• a tubular structure extending axially outward from the first end portion and defining a chamber extending along the insertion axis and in communication with the through-bore, wherein the threaded end segment is in the chamber when in the staging position;
• and
• an insert removal device engaged to the first end portion and disposed axially proximate to the insert entry port, the insert removal device including a block constructed to extend into and out of the through-bore to remove slipped tangless helically coiled inserts from the threaded end segment when the threaded end segment is axially aligned to the block.
