Bullet Flame Shape Carbide burs - 12 blades

Bullet Carbide Finishing Burs 7801, 7802 and 7803: 12 Blades, FG Shank

Eagle bullet carbide burs 7801, 7802 and 7803 are 12-blade FG finishing burs for trimming and finishing restorations. The bullet bur head, sometimes called a bullet flame shape, has a rounded tip and gently tapering sides. They are made of one-piece tungsten carbide, and each pack contains 5 burs.

What Is a Bullet Bur Used For?

• Trimming excess composite after curing
• Finishing broad surfaces and convex contours
• Smoothing restorations before polishing
• Removing excess cement or residual adhesive

A 12-blade carbide bur removes less material per revolution than a standard operative bur, which is what you want during finishing.

Code Guide

• 7801 – the smallest head in the range, for fine detail
• 7802 – mid-size head, an all-round finishing choice
• 7803 – the largest head, for broader surfaces

Typical Choices by Area

• Small Class III and Class V restorations: 7801
• Everyday anterior and posterior finishing: 7802
• Large facial surfaces and direct veneers: 7803

Why Choose a Bullet Shape?

The rounded tip doesn't dig into the surface the way a pointed bur can, and the gently tapering sides blend convex contours smoothly. That makes the bullet bur a forgiving choice for facial surfaces of anterior composites, buccal contours and the lingual surfaces of upper anteriors.

What Is a 12-Fluted Bur?

"Fluted" and "bladed" mean the same thing: the number of cutting edges on the head. Operative carbide burs usually have 6 to 8 blades for cutting tooth structure. Finishing burs have 12 or more - 12 blades for trimming and contouring, 30 blades for final finishing - so each blade takes a smaller cut and leaves a smoother surface.

How to Finish With a Bullet Bur

• Cure fully, then remove gross excess along the margins.
• Blend convex surfaces using the side of the bullet in light, sweeping strokes.
• Follow the tooth's natural contour - keep the bur moving to avoid flat spots.
• Check occlusion and contacts.
• Refine with a 30-blade bur or a fine diamond, then polish.

Use a high-speed handpiece at the speed recommended by the handpiece and bur manufacturer, with light pressure and water spray to control heat.

Bullet vs Flame Carbide Burs

The bullet bur has a rounded tip and straighter sides, which suits broad surfaces. The flame bur ends in a point and reaches finer margins and grooves; see our flame carbide burs.

12-Blade vs 30-Blade Finishing Burs

A 12-blade bur removes material faster and is used for trimming and initial contouring. A 30-blade bur cuts more finely and is used for final finishing before polishing.

Carbide vs Diamond Finishing

Carbide finishing burs cut with blades and give a controlled cut on composite. Fine and super fine diamonds abrade and are often used on enamel and ceramic. Many clinicians use carbide for composite contouring and diamonds for ceramic adjustments.

Cleaning, Sterilization and Bur Life

Before each use, pre-soak in a disinfectant suitable for carbide burs, clean ultrasonically in a bur holder, rinse, dry, pouch and autoclave following your clinic's protocol. Avoid cold sterilizing solutions and hydrogen peroxide, which can degrade tungsten carbide. Discard burs with chipped blades, corrosion or a bent shank.

Common Mistakes

• Pressing hard instead of letting the blades cut
• Holding the bur in one spot, which leaves flat areas and heat
• Working without coolant
• Using a dull bur - replace it as soon as cutting slows
