These drills are the ideal tools for gem setting and general jewellery making. They can be used to drill holes in metal, plastic and wood. This drill is manufactured from a high quality tool steel to provide a precision cut and long working life. As with all burrs and cutting tools, we recommend the use of a light lubricating oil or silicone lubricant to prevent overheating and maintain sharpness of the burr.
