Review on Pieces Mandrels Install Drywall Plastic by Matt Watson

I ordered the red set as it was the only one pictured with the spike I wanted. These are large hole saws and I wanted to secure the mandrel with two teeth that go into the hole and stabilize the cutter. It is pictured in the red set but it was not included, just a regular screw as shown in other colors. Haven't decided yet whether to return it or not. Update, the seller agreed to refund the cost of the saw kit. You reacted quickly.
