Bits produced from large-carbon metal are more durable than low-carbon metal bits due to the Houses conferred by hardening and tempering the material.
The Irwin little bit could find the money for larger space for waste removal, greater toughness (as the structure permits a Heart shank of enhanced measurement inside the flutes, as compared to the Jenning bits), or smaller manufacturing costs.
