If you drill tough metals regularly, these Drill Hulk 3/16-inch M35 cobalt steel jobber bits are built for the job. The high-speed steel with 5% cobalt is designed to handle higher heat conditions than typical HSS bits, making it a practical choice for stainless steel and other hard metals.

Each bit features a 135° split point to help start holes with less walking, plus a 3-flat shank that helps reduce slipping in the chuck. You also get a 12-piece set with a case, so you can keep spares on hand and stay productive.
