CUTTER POCKET HAVING REDUCED STRESSED CONCENTRATION
摘要
A method for forming a drag bit using displacements having a rounded end that creates a cutter pocket having a rounded rear portion. The displacement may comprise an insert on the rounded end that remains in the drag bit during and after formation. A cutter element may then be attached to the upper portion of the insert. The rounded shape of the insert provides a more even force distribution.
