60_-diamonds l Global Burs

Our dental burs utilize pioneering product design technologies to deliver exceptional performance and durability.

The “More Diamond per Diamond” product design is intended to maximize each Diamond Bur’s longevity and precision. By optimizing diamond crystal exposure and ensuring uniform distribution across the tool surface, this innovative process strengthens the bond and sharpens cutting edges, achieving a remarkable 60% increase in diamond exposure for superior durability and performance.

Triton-coating l Global Burs

To further elevate performance, the advanced “Triton” coating process is applied to reinforce diamond bonding strength, more than doubling durability for smoother, faster cutting that maintains sharpness over extended use. This coating, combined with precisely heat-treated, ground stainless steel shanks, results in tools that perform reliably in high-demand environments while preserving their cutting accuracy and strength.

The Triton bonding process ensures that 60% of each diamond is exposed, with only 40% covered by the bonding agent.

Frequently Asked Questions

Product

What is the MDT FG Diamond Barrel 811 Bur used for in dentistry?

The MDT 811 is a flat end, barrel shaped diamond bur designed for precision and control in everyday dentistry. Its cylindrical profile excels at:

  • Occlusal reduction for crown preps, especially on molars and premolars
  • Shoulder margin creation for full-coverage restorations
  • Smoothing axial walls in Class I or II cavity preps
  • Finishing composite margins, like refining a Class V restoration

✅ Real-world example: A dentist used the 811 to flatten the occlusal surface of a molar for a zirconia crown, achieving a smooth, scannable prep in under two minutes. It’s a reliable workhorse for both general and advanced restorative work, ensuring straight lines and minimal overcutting in tight posterior spaces.

Why choose MDT’s 811 bur over other brands?

At GlobalBurs, we test every bur we sell in real clinical settings - because we’re dentists, too. Here’s why MDT’s 811 stands out:

  • Vacuum-brazed, multi-layered diamond grit: Retains sharpness 30% longer than leading competitors in our tests
  • Uniform diamond distribution: Delivers consistent, chatter-free cutting
  • Stainless steel shank: Enhances torque transfer for better control
  • ISO 6360-1/2 compliant: Ensures a perfect fit and balance in all major turbines

💡 Pro tip: The 811’s durability means fewer bur changes during a busy day, saving chair time and reducing frustration. It matches or outperforms premium brands at a fraction of the cost.

Will it fit my high speed handpiece?

Yes, 100%. These diamond barrel 811 burs are an FG (Friction Grip) burs, designed for seamless compatibility with high-speed turbines, including:

  • KaVo SMARTtorque / EXPERTtorque
  • NSK Pana-Max / Ti-Max
  • Bien-Air Tornado
  • W&H Synea
  • Sirona T1 / T2

No adapters needed - just insert and start working with zero vibration or slippage.

How many procedures can I get from each bur?

Each pack contains 5 high performance burs. While labeled “single use” for compliance, clinicians report 12-20 uses per bur on enamel or composites, depending on:

  • Material hardness (e.g., dentin vs. zirconia)
  • Water spray usage (copious irrigation extends life)
  • Sterilization (autoclave at 134°C with a dry cycle)

Sustainability note: Reuse responsibly by inspecting burs under magnification and following local regulations. Proper care maximizes ROI, making each pack a cost effective choice.

What’s the grit level, and why does it matter?

The MDT 811 features medium grit, the gold standard for versatility:

  • Efficient cutting: Reduces enamel and dentin quickly
  • Smooth finish: Ideal for adhesive bonding or digital scanning
  • Balanced performance: Avoids the chatter of coarse grits or clogging of fine grits

💡 Pro tip: Medium grit is perfect for crown preps or finishing Class II composites, streamlining workflows without switching burs. MDT also offers fine and coarse grits for specialized needs - ask us for details!

Can I use it on multiple dental materials?

Absolutely. The 811 is a multi material champion, effective on:

  • Enamel and dentin - For precise cavity preps
  • Composite resins - For contouring proximal contacts
  • Porcelain and e.max - For margin refinements
  • Glass ionomer (GIC) - For smooth trimming

✅ Real-world example: A clinician used the 811 to polish a composite veneer margin, achieving a seamless transition in one pass. It’s your go to for everything from molar preps to aesthetic touch ups.

Is it suitable for zirconia or lithium disilicate (e.max)?

For light adjustments (e.g., refining margins or contact points), yes. However, for bulk reduction on zirconia or e.max, switch to MDT’s zirconia specific burs to:

  • Prevent premature bur wear
  • Avoid microfractures in the restoration
  • Save chair time

💡 Pro tip: Pair the 811 with our PLZ Polishing Kit for zirconia cases to cover both finishing and heavy reduction efficiently.

What are the specs of the MDT 811 bur?

Built to ISO standards, the 811 ensures consistency:

  • FG shank: Fits all high-speed handpieces
  • Barrel-shaped head: Optimized for flat reductions and margin creation
  • Balanced design: Minimizes vibration for precise control
  • Standard cutting length: Ideal for posterior access

Are there kits or bulk discounts available?

Yes, we’ve got options to suit your practice:

  • 5 piece packs: Perfect for both solo clinicians and bulk purchases by big clinics and labs.
  • Pre built clinical kits: Include the 811 with tapered, round and finishing burs
  • Custom bundles: Tailored for multi-op practices or dental schools
  • Bulk deals: Volume discounts and free sterilization blocks for 10+ packs
