Product Description
1/2" diameter diamond coated drill bit. Commonly used for drilling glass bottles, tiles, and craft projects.
These are coated meaning jointing the diamond compound to tools by using electro-plate process. Relatively less durable and also the tolerance is much bigger than the sintered ones. Use plenty of water for lubrication and keeping the bit cool.
