Video tutorial on 4 different methods on how to insulate screwdrivers for electrical usage. This is intended for low voltage applications where you won’t risk any harm to yourself and prevent damage on a live circuit or as added protection on professional insulated tools. For higher voltage applications, use only professionally made and tested insulated tools. When applying any of these methods, ensure the screwdriver shaft is clean. Any dirt on the surface may cause application issues or adhesion problems. Before applying any of these products, use a clean cloth and wax and grease remover for cleaning.

Step 1: Method 1
Using heat shrink:
This is available in a variety of colors, voltage ratings, and shrink rates. Some can also be purchased in a roll or pre-cut lengths. Size the piece of heat shrink accordingly, use side cutters to make it the appropriate length, then install on the screwdriver’s shaft. Once satisfied, use the heat gun to shrink the tube, applying even heat all the way around until the tube has fully shrunk and is tight around the shaft of the screwdriver.
Step 2: Method 2
Using electrical tape:
Electrical tape is available in a variety of heat ranges, thicknesses, widths, colors, voltage ratings, and application recommendations. Simply wrap the tape around the shaft, stretching each wrap ensure maximum adhesion along with half an overlap on each layer. Finally trim using side cutters for a clean finish.
Step 3: Method 3
Using liquid tape:
This too is available in a variety of ratings and colors. Make some type of wire hanger to elevate the screwdriver until the liquid tape dries. Ensure the product is mixed and apply it with the supplied brush. Multiple coats can be applied if desired, just allow the product to dry sufficiently in between coats. Remove the tape when the coating is still wet, otherwise you may have a hard time creating a clean transition edge. Dry time will vary, so consult with the product’s instructions first.
Step 4: Method 4
Using a rubber coating intended for handles:
This product will have different voltage ratings and is available in a variety of colors, so always consult with the products details. Mix the product accordingly, then dip the screwdriver shaft in the coating. Just like the liquid tape, multiple coats can be applied, allow the product to also dry in between coats too. After the final coat has been applied, let the coating cure before usage. Use a dull razor to score the tip and remove it to expose the tip of the screwdriver.
