A hole punch for a 32mm hole.
These hole punches are great for making really clean holes that are free of burrs. The holes made with this type of punch are significantly better than a hole made with a carbide drill bit or many other hole saws. These produce clean holes and can be used in mild sheet steel up to 3mm thick or stainless steel up to about 1.5mm thick. If you are looking for a really easy way to make really clean holes this is the best product for the job.
Instructions
STEP 1: To use this type of hole punch you simply use a drill but such as this stepped drill bit to drill a pilot hole.
STEP 2: Place bolt through hole.
STEP 3: Attach die and punch together from punch kit.
STEP 4: Use ring spanner to tighten bolt.
STEP 5: Keep tightening the bolt until you hear the click sound of the punch passing through the steel.
STEP 6: Remove the assembly from the hole and screw the die and punch set apart.
STEP 7: Throw away the slug.
STEP 8: Admire the perfectly clean hole that you have just made in the sheet metal. No further filing or cleaning up of the hole is required.
