Example #2 - Oblong holes: When punching a
1/4" x 3/4" oblong hole in 3/8" thick material, you
would use a 9/32" x 25/32" die.
1/4" + 1/32" = 9/32"
3/4" + 1/32" = 25/32"
Punching material 1/2" to 23/32" thick:
When punching material 1/2" to 23/32" thick, add
1/16" to the size of the punch to determine the
proper size die.
Example #3: When punching a 3/4" diameter hole
in 1/2" thick material, you would use a 13/16"
diameter die.
3/4" + 1/16" = 13/16"
Example #4 - Oblong holes: When punching a
1/2" x 3/4" oblong hole in 1/2" thick material,
you would use a 9/16" x 13/16" die.
1/2" + 1/16" = 9/16"
3/4" + 1/16" = 13/16"
Punching material 3/4" to 1" thick:
When punching material 3/4" to 1" thick, add
3/32" to the size of the punch to determine the
proper size die.
Example #5: When punching a 3/4" diameter hole
in 3/4" thick material, you would use a 27/32"
diameter die.
3/4" + 3/32" = 27/32"
Example #6 - Oblong holes: When punching a
7/8" x 1" oblong hole in 3/4" thick material, you
would use a 31/32" x 1-3/32" die.
7/8" + 3/32" = 31/32"
1" + 3/32" = 1-3/32"
PUNCH AND DIE LUBRICATION
Frequent lubrication of the punch is important to
prolong the life of the punch. Every 5 to 10
punching cycles the punch should be brushed or
sprayed with a light oil such as WD40® or
CRC®. Do not use heavy oils such as motor oil
or any type of grease.
