摘要：
Methods of forming cutting element pockets in blades of earth-boring tools include forming a first recess and a second recess intersecting at a location defining the a back of the pocket using a cutter oriented in a manner so as to avoid tool path interference with adjacent blades. A filler material is disposed in the second recess to the location of the back of the pocket. Earth-boring tools including such cutting element pockets.
