The anvil end on heads of Snap-on punches 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

The anvil end on heads of Snap-on punches 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
ということで、ヘッドのマッシュルーム化を防いでいます
