Cobalt Drill Bit Sets

Experience superior drilling performance with our Cobalt Drill Bit Sets, meticulously crafted in the USA for unmatched quality and longevity. These drill bits are machined from hardened blanks alloyed with 18% cobalt, providing a robust core that resists snapping and ensures extended tool life. The high cobalt content allows the bits to maintain their sharp edge longer while staying cooler during use, reducing the risk of overheating and wear.
Our Cobalt Drill Bit Sets feature 135° split points that are self-starting, eliminating the need for a punch or starter spot. This design ensures that the bit drills precisely where you place it, preventing wandering and promoting accuracy. The round shanks on all bits offer compatibility with various drill chucks, and the largest bits in the 29-piece set are specially cut down to fit 3/8” drill chucks, enhancing versatility.
Choose between our 13-piece set, which ranges from 1/16” to 1/4” with a quick-change shank and comes in a convenient PVC folding case, or our comprehensive 29-piece set, spanning from 1/16” to 1/2” and housed in a tough metal case with fold-out trays for organized storage. Both sets are designed to meet the demands of diverse drilling tasks, making them indispensable tools for any workshop.
