Specifications

Pro-Tip: To prevent the pilot bit from "walking" on smooth surfaces like sheet metal, use a center punch to create a small indentation before drilling. This ensures the 1/4-inch bit bites immediately, preserving the life of the cutting edge and ensuring your hole saw stays perfectly centered throughout the cut.
