• 6" long
• The anvil end on heads of Snap-on® punches and chisels are machined to a modified parabolic curve
• This design directs the striking force to the center of the tool to allow slow metal displacement
• The parabolic curve controls mushrooming to reduce chipping and splitting
• Heads should be redressed to their original shape with hand files as necessary
• The tough alloy steel is machined and differentially heat treated for optimum performance
• The hardness of the striking head is reduced to help toughness and add qualities that result in a slower mushrooming of the striking surface
