What are The Technical Requirements for Quality Carbide Burs?

Critical factors must be monitored and considered in the manufacturing process to ensure the consistent, high-quality performance of an SS White® Carbide Bur. Our extensive experience and knowledge results in the production of the highest quality of carbide burs by adhering to the 5 technical requirements for quality in manufactured carbide burs:

These essential requirements are:

  1. High grade of raw materials
  2. Blade design and angles
  3. Type of weld or solder joint
  4. Concentricity of the bur
  5. Quality Control.

Our expertise is evident in production of carbide instruments with: powerful cutting performance; maximum strength and durability; and consistent quality.

All Carbides Are Not Alike

SS White adheres to strict tolerances for concentricity of shank and head profiles during manufacturing. The result is a well-balanced carbide that: delivers minimal vibration when subjected to the rotational speeds of the dental handpiece and maximizes performance and procedural comfort for you and your patient.

SS White® brings over 160 years of continuous improvement in the design and manufacturing of dental instruments. In 1947, SS White introduced the first carbide bur to the dental profession and we continue to innovate operative, finishing and specialty carbide burs to serve the needs of modern dentistry.


Carefully designed blade structure, rake angle, flute depth and spiral angulation combined with our specially formulated tungsten carbide results in the powerful cutting performance of our burs. SS White® burs are engineered to deliver the most efficient cutting rate & performance for the most popular procedures.


Proper selection of tungsten carbide and high quality steel combined with a specialized heat treatment process and controlled welding operation creates the optimum conditions required to attain the impressive strength and durability of an SS White® bur. A study conducted at the University of Maryland confirms that SS White® 557 burs are 84.67% stronger than Midwest® Standard 557 Burs.*


SS White® is ISO 13485, EN46001 and CE Mark Certified which means an SS White® bur is manufactured to the highest quality standards. SS White reflects the importance of manufacturing to the highest standard of quality in its Quality Policy which states:

  • Total commitment to ISO 13485, MDD 93/42 EEC –Annex II and Total Quality Manufacturing
  • Provide customers with the highest valued products and services
  • Pursue continuous improvement
  • Focus on customer needs

You can depend on the consistent quality of a SS White® bur… in all ways, always.

Why do ISO Standards matter?

ISO, the International Standards Organization, is a network of the national standards institutes of 162 countries. ISO is a non-government organization that forms a bridge between the public and private sectors.

  1. The ISO certification is a voluntary audit process of the manufacturer. It signifies that outside independent evaluators have examined the manufacturer’s plant, processes and standards and have found them up to date and compliant.
  2. SS White Burs Incorporated maintains its status among an elite group of companies that have achieved world-class quality within their organization by meeting the requirements of ISO 13485 and MDD 93/42 EEC.

What makes a carbide blade sharper and last longer?

SS White carbide cutting heads are made with high quality fine-grain tungsten carbide, which produces a blade that is sharper and wears longer compared to less expensive coarse grain tungsten carbide.

  1. Blades made of fine grain tungsten carbide, retain shape even as they wear. Less expensive, large particle tungsten carbide dulls quickly as the large particles break from the blade or cutting edge. Many carbide manufacturers use inexpensive tool steel for the carbide bur shank material.
  2. For shank construction, SS White uses surgical grade stainless steel, which resists corrosion during sterilization processes used in the dental office.
