Spectrum™ ENT Surgical Burs with DuraCision™ amorphous diamond coating DuraCision coating is engineered to resist wear, temperature rise, and tissue adherence. Because of diamond’s low friction, DuraCision-coated Spectrum burs’ surface friction is reduced by as much as 85%. Easier, more thorough bur cleanup Lower temperatures during use Useful life up to five times longer Comparable or lower cost than other reusable burs Centerless-ground for better balance resulting in less stress on handpiece and surgeon Fits most surgical drills

Spectrum™ Round Diamond Burs Shaping, polishing and smoothing are the most common applications for round diamond burs. For years, surgeons have preferred round diamond burs because they offer superior control during shaping. Now Micromedics offers those traditional advantages of round diamond burs with the additional benefits of the newest diamond coating technology. Burs last up to five times longer, are comparable or lower cost than other reusable burs and easier to clean. The lower temperatures generated by the DuraCision™-coated Spectrum™ Burs mean reduced bone and tissue necrosis for safer procedures and reduced collateral injury.

Spectrum™ Round Cutting Burs Aggressive bone dissection and improved visualization are the advantages most often cited for round cutting burs. Tungsten carbide and titanium nitride-coated burs have traditionally been considered the longest-lasting burs. Now Spectrum™ Burs offer the advantages of round tungsten carbide cutting burs with the additional benefits of the newest design diamond coating technology: additional cost. All Spectrum™ Round Cutting Burs 4.5 mm and larger feature chip breakers to produce a cleaner cut and clear bone fragments from the cutting field for better visualization. Most cutting burs are sharpened to a knife edge. A knife edge breaks down (dulls) quickly. Micromedics cutting burs have a second grind, which puts more material immediately behind the cutting edge. This edge stays sharp longer. This is an exclusive feature of Micromedics’ burs.

DuraCision™ Amorphous Diamond Coating
Diamond is an excellent material for dissection because it is hard, sharp and nearly frictionless. Micromedics DuraCision™ coating provides these advantages for our Spectrum™ Surgical Burs by creating a diamond film over the entire bur tip, not just its diamond particles. DuraCision Coating is engineered to resist wear, increases in temperature and tissue adherence. Because of the diamond’s low friction, DuraCision Coated Spectrum Burs’ surface friction is reduced by as much as 85%. DuraCision coating’s coefficient of friction is like natural diamond, 0.10 to 0.15, compared to uncoated tungsten carbide’s 0.65 or higher. DuraCision-coated burs’ reduced friction results in lower temperature at the surgical site, reduced tissue and bone necrosis, decreased wear, increased bur life.

Harder, For Better Performance
For cutting instruments, hardness is a key to long term performance. DuraCision coating has exhibited a wear factor more than 100 times better than conventional tungsten carbide surfaces. It’s because our DuraCision coating produces a dramatically higher Vickers hardness rating.

Both Spectrum™ Round Diamond Burs and Spectrum™ Round Cutting Burs are available in notch types to fit all popular rotary hand instruments and in lengths of 45 to 70 mm. Osteonstyle burs are available in 30, 38 and 48 mm lengths. For assistance with ordering or for additional information, simply contact Micromedics.
