The Busch® Round Burs - Fig. 1 - 2.70 mm (ISO #027) are expertly engineered to deliver unmatched precision and performance in jewelry making, fine metalworking, and detailed craftsmanship. Made from premium tungsten vanadium steel, these burs offer exceptional strength, superior edge retention, and long-term durability, making them ideal for repetitive, high-precision work.
With precision-machined cutting teeth, these round burs deliver clean, consistent results with every use—reducing chatter, minimizing heat, and producing smooth finishes on a variety of metals, including gold, silver, platinum, and more. The rounded head shape enhances control and access to tight or curved areas, making them indispensable tools for engraving, stone setting, drilling, shaping, texturing, and deburring.
Measuring approximately 1-3/4" in length and featuring a standard 3/32" (2.35 mm) shank, these burs fit most rotary tools, including popular systems like flex shafts, Dremels, and micromotors.
To get the best performance and extend tool life, it is highly recommended to use a cutting lubricant such as Busch Lube-Stik. Lubrication improves cutting efficiency, reduces friction and heat buildup, and preserves the sharpness of the bur edges.
Each pack includes 6 precision-engineered burs, all manufactured in Germany—a country globally recognized for high-precision tools and exceptional craftsmanship.
