Busch Twist Drill are supplied mounted on a 2.35mm shank that fits most pendant drills and micromotors. These drills start at 0.50mm and go up to 2.30mm. The working length of the twist drill is 12.00mm.
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.
