The proper die clearance depends on the type and thickness of the material you're punching. Softer, thinner materials require less clearance, while harder, thicker materials require more. Use the clearance chart above to determine whether to add 1/32", 1/16", 3/32", or 1/8" to your punch diameter when selecting a die.

To maximize die life:

• Apply Punch-Easy® lubricant every 5–10 punches.
• Use the correct punch and die clearance for your material.
• Make sure the punch stripper fully contacts the material before punching.
• Never punch material that is thicker than the diameter of the punch.
• Ensure the punch and die are properly aligned before punching.

Following these guidelines will help reduce wear and extend the life of both your punch and die.
