Needle D's for Angle Grinders: The new standard for hole bit performance. The Crowne Needle - 8mm (5/16") diamond drill bit offers a versatile solution for drilling precise, clean holes in a variety of hard materials using your impact driver or standard drill. Its 8mm diameter is ideal for numerous applications, while the superior diamond coating ensures chip-free results and long-lasting performance. This bit features a 1/4 inch hex shank for quick and secure connection. Problem: Many projects require holes that are slightly larger than what a 6mm bit can provide but still demand precision and a clean finish. Using standard drill bits on hard, brittle materials often leads to inaccurate holes, chipping, cracking, and wasted materials. Solution: The 8mm Needle diamond drill bit bridges the gap, providing the perfect balance of size and precision. Its high-quality diamond coating and dry-cut technology, combined with the controlled power and speed of your impact driver or cordless drill, allow for controlled drilling in tile, porcelain, ceramic, granite and other hard materials. High-speed hole-making and a long lifespan.
