Inverted Cone Burs | Fig-3/24 | BUSCH Krause Burs | Fig-256/FK | BUSCH Mounted Saw Burs | Fig-231S/45 | BUSCH
With an inverted cone bur, you can make flat-bottomed undercuts, cut tapered slots, and start seats in irregularly shaped bezels. Since these burs can get into tight areas, you can also clean inside bezels and channel settings. You can use them for texturing, as well. Slender and aggressive, Krause burs are designed to get into the tightest of spaces. The slim contour allows you to easily remove excess solder from joints, which makes this bur very popular for jewelry repair.  The taper allows you to install hinges and to fine-tune openings in box clasps and other mechanisms. You can also create notches for prong settings. Similar to the wheel burs except tapered on the top and bottom to a knife-like edge, mounted saw burs are perfect for scoring lines. They have cutting flutes on the top and the bottom for more versatility.
