Busch Cone Burs

The Basics

• Cone Burs have tapered sides that come to a point at their tip. They're used for enlarging and deburring holes and for repositioningflush settings before refining the seat. Also available with round or flat ends.
• Vanadium Steel burs are economically priced. They cut precisely when new, but don't retain their sharpness as long as other steel alloys. They're used at low speeds.
• 3/32" dia. shanks are the jeweler's preferred standard for burs and small rotary tools. They fit the adjustable chucks found on most flexshaft handpieces as well as 3/32" handpiece collets.
