664dr Diamond Flipbit Drill Bit, 1/16 In. & 3/32 In., 1/8 In. Shank

The Dremel 664DR Diamond Flipbit is a dual-function drill bit that lets you switch between two hole sizes with a single tool. By simply flipping the bit over, you can select between a 1/16 inch and 3/32 inch hole without changing accessories. This innovative design saves time and streamlines your toolkit for drilling, hole enlargement, and fine cutting tasks on delicate and hard materials.

Ideal for glass, ceramic wall tile, glass block, stone, and glass bottles, the 664DR is popular with jewelry makers, artisans, and hobbyists creating ornaments, art, and home decor. The diamond coating delivers long-lasting durability compared to standard drill bits, while the fluted design clears debris efficiently to keep holes clean and drilling smooth on both flat and contoured surfaces.
