Product Details
The THUNDERBOLT 15PC Black Oxide Drill Bit Set is designed for heavy-duty performance on the jobsite, featuring a Black Oxide coating that reduces heat build-up and provides corrosion resistance. This set includes 15 jobber length drill bits in sizes: 1/16", 5/64", 3/32", 7/64", 1/8", 9/64", 5/32", 11/64", 3/16", 13/64", 7/32", 1/4", 9/32", 5/16", and 3/8". The thicker core enhances strength and protects against side-load breakage, while the parabolic flute design efficiently clears chips and debris to maintain cooler operation. The 135-degree split point tip ensures a precision start and prevents walking, facilitating fast and accurate hole drilling. Each bit features a 3-flat secure grip shank to reduce slipping in the chuck. The set comes organized in a customizable indexed case compatible with PACKOUT systems, ensuring easy access and storage.
