14 Piece Black Oxide Drilling Bit Set

Widely USED: You can use these bits on either wood, plastic, or thinner metals with ease. STORAGE: A plastic molded case has rubber foldout slots for each of the bits included in this set. These slots are labeled, as well, so you can always be sure what size you're using on the job. SPLIT POINT TIP: These bits have points at their ends which diverge at a 135-degree angle. This design enables the bits to easily grip into your drilling project, providing clean holes without wobbling or slipping. BLACK OXIDE FINISH: The materials provide superior durability and up to 50% improved lifetime compared to standard high-speed steel drill bits. They also reduce friction between the bit and drilling subject, giving you improved hole boring speeds.
