SUVA Shards Sintered Diamond Burs - Drums

SUVA's sintered diamond burs provide reliable cutting action and outlast standard plated lapidary burs by 5-10 times.

Use for shaping and carving lapidary minerals and gemstones, glass, opals, porcelain, metals, or other hard materials with your Foredom or Dremel rotary tool. Be sure to maintain and re-shape your valuable sintered burs with the companion Diamond Re-Shaping Block. Inland-brand sintered burs are also available in additional grits and sizes.

Follow up with Diamond Pacific Nova Sanding Points and felt burs charged with your favorite lapidary polish or phenolic burs with diamond paste.
