The unique design of the Late 2012-2015 iMacs require the cutting of the foam tape on the display to get inside. This tool comes in two parts:
• The handle is made of tough, laser-cut Nylon and easily accomodates the cutting wheel while providing plenty of grip.
• The cutting wheel is specifically designed to slip in the hair-thin gap between the display and the aluminum frame, then easily cut the foam holding the two pieces together.
(this product includes 5x wheels. The handle can be purchased separately, these wheels can be used with both the iFixit handle and the Apple Original handle)
There is a delicate procedure to removing the displays on these generations of iMac, which require a new VHB tape kit and cutter wheel each time the display is removed. This handle can be reused, but is required in order for the cutter wheel to get the correct depth needed to separate the VHB tape from the main housing unit of the iMac.
Please Note: This is not an easy job to undertake, so is not recommended without prior training.
