Diamond Bur #856-018 Super Coarse Round End Taper FG, Pk3

High-speed crown work often requires a tapered profile that enters the surface cleanly, and a Diamond Bur #856-018 Super Coarse Round End Taper FG, Pk3 is shaped for exactly that role. The round-ended taper gives a guided cutting path during early reduction, and the 018 head size offers a balanced width for crown preparation, axial shaping and broader contouring tasks.

Key Features

• Super coarse grit for rapid enamel and restorative material reduction
• Round end taper profile for controlled depth and axial form
• 018 head diameter for balanced coverage during early shaping
• High-quality FG diamond construction for high-speed handpieces
• 3 pieces per pack (price listed per pack)

Understanding the Diamond Bur #856-018 Super Coarse Round End Taper FG

When you need a tapered bur that enters the surface decisively and gives you a controlled cutting path, the Diamond Bur #856-018 Super Coarse Round End Taper FG, Pk3 is one of the profiles that feels familiar to most clinicians. This diamond-coated bur is made for high-speed handpieces. Its head, shape, grit and diameter each point to how it performs when early reduction begins.

Here’s a breakdown of what the name represents:

• #856-018: This identifies an 856-018 diamond bur with a classic round-end taper body and an 018 head diameter. The size provides a balanced width for axial reduction and early contouring.
• Super Coarse Grit: A super coarse round end taper bur uses larger diamond particles that drive fast enamel and restorative removal during the first passes.
• Round End Taper Shape: The tapered body guides the wall form, and the rounded tip helps create controlled internal angles during early shaping.
• Friction Grip (FG): This indicates compatibility with standard high-speed turbines used throughout restorative workflows.

Compared with the 855 or 850 profiles, the 856 sits in the middle in terms of head width and taper intensity. The 855 offers a broader footprint for more assertive reduction, while the 850 produces a narrower, more refined taper. The 856 strikes a balance between coverage and control, which is why it fits naturally into crown and operative stages where defined tapering is required.

Clinicians choose an 018 diameter when they want a cutting width that covers enough surface area to progress efficiently without losing precision. Common reasons include:

• Establishing axial reduction during crown preparation
• Early contouring on enamel and restorative surfaces
• Creating a tapered entry path before switching to smaller diamond burs for finishing

Clinical Applications & Benefits of the 856-018 Super Coarse Bur

At the start of a prep, the Diamond Bur #856-018 Super Coarse Round End Taper FG, Pk3 gives you the diameter and taper needed to clear material with intent. The rounded tip directs the entry point, and the super coarse grit drives the first stage of reduction. Here’s how this profile typically performs in clinical use:

• Establishing axial form early: As part of the category of round end taper diamond burs, the tapered body helps establish axial form during the first passes. The 018 diameter supports steady wall shaping as the outline begins to develop.
• Defining occlusal pathways: The profile guides the early occlusal cuts and tracks cleanly along tooth slopes as you create clearance. This helps set up the outline before refinement.
• Fast entry through enamel and restorations: A super coarse dental bur engages dense surfaces with intent during the initial stage of reduction. This is helpful when clearing older restorative material before moving into finer shaping.
• Shaping internal angles with control: The rounded end supports controlled internal line angles and helps reduce abrupt transitions as the early form takes shape.
• Setting the base through bulk reduction: The abrasive surface removes bulk material quickly in the first phase of the prep, creating a base that can be refined with smaller instruments.
• Creating width while maintaining access: Among the FG diamond burs Australian clinicians use, the 018 size gives enough width to progress efficiently, while still keeping access manageable. It transitions well before switching to finer dental burs for finishing.

How to Choose & Use Round End Taper Diamond Burs Effectively

When early reduction needs confident engagement and a guided taper, the Diamond Bur #856-018 Super Coarse Round End Taper FG, Pk3 becomes a strong starting point. Technique, grit choice and handpiece control all influence how predictably this profile performs.

1. Choosing grit for the first pass

• Super coarse grit sets the pace for rapid initial cutting.
• Selecting 856 diamond burs at this grit level helps clear enamel and older restorative surfaces during the early stage of a crown prep.
• Medium grit is introduced once axial form is defined. Fine grit follows for final refinement and margin finishing.
• This progression supports a controlled transition from bulk cutting to precision work.

2. Using the round end taper for margin control

• The tapered body and rounded tip give a predictable approach to internal angles and margin outline.
• A super coarse diamond bur guide often highlights how the rounded tip helps avoid sharp internal corners.
• This is particularly useful during early shaping before switching to narrower finishing burs.

3. Handpiece speed and cooling

• Stable turbine speed supports consistent cutting contact.
• A steady water spray limits heat generation during extended contact with enamel.
• Applying controlled pressure helps maintain an even reduction path.

4. Sterilisation and storage routine

• Correct handling helps preserve the diamond surface for more cycles.
• Make sure to rinse immediately after use, then place in an ultrasonic cleaner.
• Dry thoroughly before autoclaving to protect the abrasive layer.
• This routine helps the bur stay consistent from one appointment to the next.

5. Knowing when a bur has worn

• Wear becomes clear once the first few contacts with the tooth slow down.
• Dental bur selection tips include watching for reduced cutting speed.
• Vibration signals the deterioration of the abrasive surface.
• Needing more force to progress means the bur should be replaced.
