Finish jobs faster by easily switching between drill bits in seconds. Dremel's 664DR Diamond Drill FlipBit features a one-of-a-kind design allowing DIYers to drill two hole sizes with one accessory by simply flipping the bit over to select a different size. The dual bit design allows you to pick one size to make 1/16 In. (1.6 mm) hole; flip the bit over to the other side to make a 3/32 In. (2.1 mm) hole. The FlipBit is ideal for drilling in both flat and contoured surfaces and can be used to enlarge holes and make small cuts. The 664DR features a diamond coating which provides superior life compared to other diamond drill bits; its fluted design makes eliminating material faster compared to core bits. Makers will find the 664DR ideal for creating jewelry, ornaments, art, and decor. The 664DR Diamond Drill FlipBit can be used on glass, ceramic wall tile, glass block, stone, and glass bottles.
