High speed steel round (ball) burs with 3/32" shanks.
High Speed Steel (HSS) burs strike a balance between cost and durability. They maintain their hardness (temper) better than vanadium steel and cost less than carbide steel.
Round Burs are useful for de-burring or enlarging holes, carving recesses for sweat soldering, and refining stone settings. Because of their shape they can be used at any angle.
