TF-12 Burs

TF-12 burs are diamond-coated dental rotary instruments used with high-speed handpieces for precision cutting, grinding, and finishing of tooth structure and restorative materials. They belong to a series of taper flat end (“TF”) burs, typically referenced by an ISO shape code such as 173/016. These burs feature a tapered, flat end geometry and a diamond grit coating that provides efficient cutting performance.

Key Specifications (Typical)

• Shape: Tapered Flat End (TF series)

• ISO Size: 173/016 (approx. 1.6 mm head diameter).

• Head Length: ~10 mm (varies by manufacturer).

• Total Length: ~21–22 mm (for friction-grip high-speed).

• Material: Stainless steel shank with diamond grit working surface.

• Grit Options: Usually medium/standard grit (some variants may be fine or extra-fine)

• Compatible Handpiece: High-speed (friction grip) dental handpieces.

Primary Uses in Dentistry

TF-12 burs are versatile and commonly used for:

• Crown & bridge preparation – shaping and reducing tooth surfaces for proper fit of crowns and bridges.

• Cavity preparation – removing caries and defining cavity walls.

• Margin refinement – creating smooth, controlled margins on prepared teeth.

• Tooth contouring and occlusal adjustment – refining anatomy and occlusal contacts.

• Finishing restorations – smoothing and polishing composite or ceramic surfaces.

Advantages

 High cutting precision due to diamond abrasive surface

 Reduced vibration and smooth performance

 Efficient material removal with minimal chatter

 Compatible with standard high-speed air turbine handpieces

Variants and Grit Options

While TF-12 usually denotes the standard medium grit version, manufacturers often offer variants such as:

• TF-12F – Fine grit

• TF-12EF – Extra fine grit

  These provide options for more delicate finishes or polishing tasks.

Typical Packaging

Dental burs like TF-12 are usually sold in:

• Singles or small packs (e.g., 5 pcs)

• Bulk packs for clinical/lab use (e.g., 25–100 pcs)
