Diamond Burs - Shop Premium Dental Burs Online

Dental diamond burs are rotary instruments coated with diamond particles. They cut, shape and finish hard tissue such as enamel and dentin, as well as ceramics and composite, with precision and control. Eagle Dental Burs offers a wide range of diamond burs made in Israel, in every common shape, grit and shank type, with express worldwide shipping and a 100% satisfaction guarantee.

What Are Diamond Burs Used For?

Restorative dentistry: cavity preparation, removing old restorations and contouring composite, with minimal removal of healthy tooth structure.

Cosmetic dentistry: veneer and crown preparation, where depth control (see our veneer depth cutting burs and precision markers) and a smooth finish matter.

Endodontics: access cavity preparation with endo access diamond burs and minimal invasive diamond burs.

Orthodontics: interproximal reduction (IPR) and enameloplasty with mosquito IPR burs and our IPR tools.

Periodontics and oral surgery: gingival contouring, crown lengthening and bone contouring (see our surgical burs).

Prosthodontics and dental labs: crown, bridge and abutment preparation, plus finishing prostheses in the lab (see our dental lab burs).

Diamond Bur Shapes

The head shape decides what a diamond bur does best. The most popular shapes in our range:

• Round burs - access, caries removal and cavity preparation
• Inverted cone burs - undercuts and flattening cavity walls
• Round end tapered burs and flat end tapered burs - crown preparation and margins
• Flame burs - interproximal areas and esthetic contouring
• Wheel burs - reduction and shaping in crown preparations
• Cylinder burs - bulk reduction and levelling surfaces
• Football burs and 330 pear burs - occlusal surfaces and conservative cavity preparation
• Occlusal reduction burs and gross reduction burs - fast, even reduction
• Needle burs - fine detail work in tight spaces

Shank Types: FG, RA and HP

Friction grip (FG) shanks fit high speed turbine handpieces and are the most common choice for chairside work (see our high speed burs). Right angle (RA) shanks fit slow speed contra-angle handpieces and suit finishing, polishing and surgical work (see our slow speed burs). Handpiece (HP) shanks fit straight handpieces, mostly used in dental labs and surgery.

Diamond Bur Grit Guide

Grit is identified by the colour ring on the shank: black is super coarse, green is coarse, blue is standard (medium), red is fine and yellow is extra fine. Use coarser grits for fast bulk reduction, standard grits for preparation, and fine or extra fine grits for finishing and smoothing margins.

Diamond Burs vs Carbide Burs

Diamond burs cut hard materials such as enamel and ceramic efficiently and give a controlled finish. Carbide burs cut softer materials such as dentin, amalgam and metal quickly and leave a smoother surface. Many procedures use both.

How Diamond Burs Are Made

Diamond particles are bonded to the bur head either by electroplating, which applies a single layer of diamond for sharp, aggressive cutting, or by sintering, which embeds several layers in a metal matrix for a longer working life. The particles are sorted by size, which gives each grit its cutting behavior.

Using and Caring for Diamond Burs

Use light, steady pressure at the speed recommended by the manufacturer, with plenty of water cooling to protect the pulp and extend bur life. Clean burs after every use, sterilize them according to the instructions, and replace any bur that is worn, clogged or bent. A worn bur cuts slower and generates more heat.
