How to punch holes in sheet metal

Hole punch pliers are easy to use. They feature a pin at the end of the pliers’ jaws, and when force is applied to them you can punch a clean hole through your sheet metal.

Top tips when punching holes in sheet metal

  • To get the most accurate hole punch possible, mark up your sheet metal or pendant blank using a black marker. This will also help you to measure accurate spacing between multiple holes if your design requires it.
  • Want to ensure accuracy as you use your metal hole punch? Start by using a centre punch and hammer on a steel block to create a small dent where you’ve previously marked your metal. This will leave you with a guide as to where to position your hole punch.
  • Remember to punch the hole on the side of the sheet metal or blank that will face outwards. This will ensure that any sharp edges that are created will not be visible. The metal hole punch is quite accurate, so you should only need to file any sharp edges before moving onto buffing and polishing your design.
  • Having trouble getting rid of tiny burrs on the inner edge of the hole that’s been punched? Using a forward and twisting motion, file the inner edges of the hole using a round needle file.

How to pierce sheet metal with your jeweller’s saw

Another method of creating holes in your sheet metal is by using your jeweller’s saw. This method is a proven way of piercing your metal to create intricate cut out patterns in your metal sheet. It may seem complicated to produce cut out patterns in a ring, for example, but once you’ve got the basics of piercing and sawing perfected the possibilities are endless!

Note: It is not advised to use your jeweller’s saw to create an accurate hole for jump rings. This is best left to hole punches or to pendant drills for a more accurate result.

How to pierce metal

  • What cut out pattern are you creating in your sheet metal? The best place to start for an accurate result is with a design laid out on paper. Make sure you’re happy with the design on paper without making any marks on your sheet metal.
  • Happy with your design? Now you can carefully lay it out on your sheet metal and fix it in place using double sided sticky tape.
  • Now take your trusty centre punch, jobbing hammer, and steel block. Place your sheet metal on your steel block and position your centre punch at a central point in your cut-out design. Tap your hammer to leave an indentation on the sheet metal.
  • Depending on the tools you have, you’ll now need to punch or drill a hole where the indentation has been made to produce an accurate hole in your sheet metal.
  • To start sawing your cut-out design, you’ll need to take a saw blade and your saw frame. Place the blade into the end of the saw frame (closest to the handle) and tighten. Feed the other end of the saw blade through the hole you’ve created in your sheet metal.
  • Quick check: Have you attached the saw blade to the frame with the teeth of the blade running in the right direction? Carefully run your finger along the saw blade to check the teeth are running in a downward direction.
  • Now you’re ready to saw your intricate cut out pattern! Start by running your blade in a slow upward motion. This will give you a nice starting point to start sawing in a downward motion, making sure your saw frame is parallel to your work bench.
