Description: Cutting Efficiency and Precision

Tungsten carbide (WC-Co) burs offer high cutting efficiency thanks to their hardness and blade geometry. Vibration is minimal, which improves operator control and helps maintain patient comfort.

Wear Resistance and Longevity

WC-Co alloy burs have superior wear resistance compared with steel and other alloys. They withstand repeated sterilization cycles and keep their edges for a long time.

Heat Control and Tissue Protection

Thanks to high cutting efficiency, isolated heat build-up occurs when used with low pressure. This reduces the risk of pulp tissue damage. Chip evacuation is optimized.

Material Compatibility and Multi-Purpose Use

Can be used across a wide material range such as metal crown materials, composite, and amalgam. Metal-cutting characteristics make some designs especially suited to metal milling.

Geometry and Design Features

Blade angle, spiral angle, and flute count directly affect bur performance. Aggressive (positive rake angle) blades provide fast cutting, while negative rake or radial-angle designs increase fracture resistance.

Care and Use Precautions

• Inspect the bur frequently and watch for microcracks or edge damage.
• Apply ultrasonic cleaning and appropriate sterilization protocols.
• Avoid maximum pressure at high speeds; overload shortens material life.
• Choose a flute design that will not obstruct chip flow.

Important Note

Tungsten burs tend to fracture on impact, drops, or blows. Work without pressing hard and take care to avoid drops and impacts.

Speed Recommendation

Use at max. 40,000 rpm.
