The Busch® Pointed Burs FIG 5, 2.90mm (ISO #029) are professional-grade tools engineered for detailed jewelry-making and precision metalwork. Made from premium tungsten vanadium steel, these burs offer outstanding strength, wear resistance, and durability—making them a go-to choice for jewelers, engravers, and metalsmiths around the world. With a 2.90mm diameter and 42° pointed cutting angle, these burs are ideal for precision carving, engraving, stone setting, and shaping on a wide variety of materials, including gold, silver, platinum, brass, and other metals. The maximum safe speed varies depending on the
bur size, and this information is provided on the packaging. For optimal
cutting efficiency and to extend the lifespan of the burs, a proper lubricant
is recommended during use. The burs measure approximately 1-3/4" long
with a 3/32" shank, ensuring compatibility with most standard
rotary tools.
Busch® Pointed Burs are available in various
sizes, ranging from 0.60mm to 5.00mm, and feature a 42.0° angle
