DRIVDOR 5/32

• 5" 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
