Made in Germany

Frank Dental is internationally recognised for producing premium-quality dental burs and rotary instruments.

Every C.283K Tungsten Carbide Bur is manufactured in Germany under strict quality control standards to ensure:

• Consistent cutting performance
• Accurate blade geometry
• Exceptional durability
• Reliable clinical outcomes

German engineering and manufacturing precision have made Frank Dental burs a trusted choice among dentists, prosthodontists and dental laboratories worldwide.

---

Exceptional Cutting Efficiency

One of the primary advantages of the Frank Dental C.283K is its outstanding cutting efficiency.

The combination of:

• Tungsten carbide hardness
• Optimised flute design
• Precision cutting edges

allows the bur to cut efficiently through restorative materials while minimising operator effort.

Benefits include:

• Faster material removal
• Reduced chair time
• Improved clinical productivity
• Enhanced cutting precision

The sharp cutting blades slice through material cleanly rather than grinding, helping maintain efficiency throughout the procedure.

---

Reduced Vibration for Better Control

The Frank Dental C.283K has been designed to minimise vibration during operation.

Reduced vibration provides several important clinical advantages:

Improved Precision

Allows more controlled adjustment of restorations.

Better Patient Comfort

Smoother cutting action reduces unpleasant sensations.

Enhanced Visibility

Improved control allows greater accuracy around margins and delicate restorative surfaces.

Reduced Operator Fatigue

Less vibration results in a more comfortable working experience.

---

Superior Wear Resistance

The tungsten carbide-cobalt alloy used in the C.283K provides exceptional wear resistance.

Compared with conventional steel burs, the Frank Dental C.283K offers:

• Longer service life
• Improved edge retention
• Consistent cutting efficiency
• Reduced replacement frequency

This makes the bur a cost-effective solution for busy dental practices.

---

Designed to Withstand Repeated Sterilisation

The Frank Dental C.283K has been developed to withstand repeated sterilisation cycles while maintaining its cutting performance.

Benefits include:

• Long-term durability
• Reliable performance
• Consistent cutting efficiency

With proper maintenance and sterilisation protocols, the bur provides excellent longevity.

---

Excellent Heat Control and Pulp Protection

Heat generation is an important consideration during restorative procedures.

Excessive friction can potentially affect:

• Pulp vitality
• Patient comfort
• Restorative materials

The Frank Dental C.283K minimises heat generation through:

• Efficient cutting blade geometry
• Sharp cutting edges
• Effective chip evacuation

When operated at the recommended speed and with light pressure, isolated heat build-up is minimised, helping protect the pulp and surrounding tooth structure.

---

Optimised Chip Evacuation

Efficient chip evacuation is essential for maintaining cutting performance.

The flute design of the C.283K has been engineered to:

• Remove debris efficiently
• Prevent clogging
• Maintain cutting efficiency
• Improve visibility

Optimised chip flow helps ensure smooth cutting performance throughout the procedure.

---

Suitable for a Wide Range of Materials

One of the major advantages of the Frank Dental C.283K is its versatility.

The bur can be used on:

Amalgam

Efficient removal and contouring of amalgam restorations.

Composite

Trimming, shaping and adjusting composite restorations.

Precious Metals

Adjustment and refinement of gold and other precious alloy restorations.

Non-Precious Metals

Efficient cutting of cobalt-chromium and other metal alloys.

Crown and Bridge Materials

Adjustment of restorative surfaces and margins.

Laboratory Applications

Fine adjustment and finishing of prosthetic work.

---

Advanced Cutting Geometry

The performance of the Frank Dental C.283K is directly influenced by its advanced blade design.

Key features include:

Precision Flute Design

Improves chip evacuation and cutting efficiency.

Optimised Blade Angles

Promote smooth material removal.

Enhanced Fracture Resistance

Supports durability during demanding procedures.

Efficient Cutting Performance

Allows rapid and controlled material removal.

The result is a bur capable of delivering exceptional performance across a broad range of clinical situations.

---

Recommended Speed

Maximum Speed: 40,000 RPM

For optimal performance, Frank Dental recommends operating the C.283K at a maximum speed of 40,000 RPM.

Operating within this range helps achieve:

• Maximum cutting efficiency
• Reduced heat generation
• Improved safety
• Extended bur life

---

Maintenance Recommendations

To maximise longevity and performance:

Inspect Frequently

Check for:

• Edge wear
• Microcracks
• Blade damage

Ultrasonic Cleaning

Clean thoroughly after use.

Sterilise Correctly

Follow standard autoclave protocols.

Avoid Excessive Pressure

Allow the bur to cut efficiently without forcing it.

Maintain Chip Flow

Use proper cutting techniques to prevent clogging.

---

Important Handling Information

Although tungsten carbide is extremely hard, it is inherently brittle.

The Frank Dental C.283K may fracture if:

• Dropped
• Impacted against hard surfaces
• Subjected to excessive force

To maximise service life:

✔ Avoid dropping the bur

✔ Avoid excessive pressure

✔ Handle carefully during cleaning

✔ Store securely

Proper handling significantly extends bur longevity and preserves cutting performance.
