METHODS FOR FORMING EARTH-BORING TOOLS HAVING CUTTING ELEMENTS MOUNTED IN CUTTING ELEMENT POCKETS AND TOOLS FORMED BY SUCH METHODS

Methods of forming earth-boring tools include using a plasma spray device to gouge at least one recess through a hardfacing material and into a body. At least a portion of the recess may define a cutting element pocket in which a cutting element may be received and bonded. The recess formed using th...

Zusammenfassung:	Methods of forming earth-boring tools include using a plasma spray device to gouge at least one recess through a hardfacing material and into a body. At least a portion of the recess may define a cutting element pocket in which a cutting element may be received and bonded. The recess formed using the plasma spray device optionally may be further machined to form the cutting element pocket. Earth-boring tools are fabricated using such methods.
