Dental Burs

Dental Burs — Cutting, Finishing and Polishing on Every Shank

A bur is the working tip of almost every rotary procedure, and the right one is chosen by three things at once: what it is made of, which handpiece it fits, and the job it has to do. Diamond grit abrades, carbide blades cut, and a graded polisher smooths — mounted on a friction-grip shank for the high-speed airotor, a latch-type contra-angle for the slow handpiece, or a long straight shank for the lab. This category runs the full spread, from single blister burs to labelled procedure kits, for restorative, endodontic, prosthodontic and surgical work.

Burs by shank and material

Airotor diamond burs (FG)

Friction-grip diamond burs are the high-speed workhorses for crown and veneer preparation, occlusal reduction, enamel cutting and zirconia adjustment, coming in round, taper-flat-end, taper-round-end and needle shapes to match the reduction. The Mani Diamond Airotor Burs (TF Series) is a taper-flat-end FG diamond of this kind.

Airotor carbide burs (FG)

Tungsten-carbide FG burs cut with bladed flutes rather than grit, giving higher efficiency on enamel and metal and a cleaner margin — the choice for caries removal, crown cutting and access cavities. The NewDiamond Cross-Cut Taper Fissure FG Carbide is a cross-cut fissure carbide for the airotor.

Contra-angle and straight-handpiece burs

Lower-speed CA (2.35 mm latch) and straight HP shanks handle deep-cavity caries removal, prosthetic adjustment, lab-bench trimming and chairside ceramic work where the airotor is too fast. The Pivo Micromotor Burs Kit (Contra-Angle, Set of 4) is a slow-handpiece diamond set.

Composite, porcelain and zirconia polishers

Multi-grit diamond, ceramic and silicone polishers restore surface gloss and cut plaque retention at a restoration margin, stepping from pre-polish to high-shine without paste on some systems. The Youdent Diamond Polishers Kit for Zirconia (HP) is a polisher set for zirconia and metal.

Trimming and finishing burs

Fine multi-bladed carbide finishing burs — egg, needle and taper-pointed — take the final pass on composite, occlusal anatomy and porcelain margins, where a cutting diamond would leave scratches too deep to polish out. The SuperEndo Composite & Porcelain Finishing Bur Kit gathers finishing burs for composite and porcelain restorations.

Procedure-specific bur kits

Pre-selected kits put every bur a common procedure needs — crown prep, endo access, veneer prep, IPR, shoulder and cavity preparation — in one labelled block, saving chair time and keeping margin geometry consistent. The Prima Crown Preparation Carbides Kit is one such crown-prep kit.

Where burs are used

Burs run through nearly every operative appointment: Class I–V cavity preparation, crown and bridge reduction across occlusal, axial, chamfer and shoulder, veneer depth-cutting and labial reduction, endodontic access and pulp-chamber deroofing, crown removal, composite and porcelain finishing, zirconia adjustment, interproximal enamel reduction in orthodontics, inlay and onlay prep, and surgical bone cutting or impacted-tooth sectioning. Each of those maps to a material, a shank and a head shape, which is why a practice keeps a spread rather than a single box.

Picking the right bur

Reach for airotor diamond on crown and veneer prep for the fastest, polishable reduction, and airotor carbide for caries removal and crown cutting where blade efficiency on enamel and metal wins. Drop to a contra-angle or HP bur for slow-speed caries removal and lab trimming, and keep 12-blade finishing burs strictly for the final pass — a cutting diamond leaves scratches finishing cannot recover. A procedure kit is worth it where shape selection repeats, and any diamond or carbide is retired after roughly 8–12 uses, since a dull bur overheats the tooth and leaves poor margins. For a shape-by-shape walkthrough, our guide to the types of burs in dentistry covers the full range.

Bur brands at Dentalkart

The range spans Mani, Prima Dental, TriHawk, NewDiamond, Hudens, Pivo, Ultradent, Youdent, SS White and SuperEndo, covering airotor diamond and carbide, contra-angle and HP burs, polishers, 12-blade finishing burs and procedure-specific kits. Each product page states the shank, head shape, grit and pack size so a bur can be matched to the handpiece and the step before ordering.

Why buy burs from Dentalkart

Every bur, polisher and kit here is sourced from the manufacturer or its authorised Indian distributor and ships sealed with its batch and expiry on the blister or kit case, so a clinic knows what it is putting in a handpiece. Burs order alongside the rest of the restorative workflow — the bonds and etchants that follow a preparation sit in the same catalogue — with delivery across the country.

What types of dental burs are there?

Dental burs split by material and shank. The two materials are diamond, which abrades, and tungsten carbide, which cuts with blades. The shanks are friction-grip (FG) for the airotor, contra-angle (CA, 2.35 mm) for the slow handpiece, and straight (HP) for the lab. Within each, burs vary by head shape — round, fissure, taper, pear, needle — grit and length.

Diamond or carbide bur — what is the difference?

Diamond and carbide burs differ in how they cut and where they suit. Diamond grit abrades quickly through enamel, ceramic and zirconia and leaves a rougher, polishable surface, ideal for crown and veneer reduction. Carbide blades cut cleanly through dentine and metal with a sharper margin, which suits caries removal, crown cutting and the 12-blade finishing of composite.

How many times can a bur be reused?

A diamond or carbide bur is good for roughly 8–12 clinical uses before it should be retired. A worn bur needs more pressure, overheats the tooth and risks the pulp, and leaves poorer margins. Inspect each one under magnification before use and discard any with chipped diamond coating, missing blades or visible flattening, regardless of the use count.

Which bur kit suits routine crown preparation?

For routine crown work a dedicated crown-prep kit is the efficient choice, since it groups the airotor diamonds and carbides for occlusal and axial reduction, the chamfer or shoulder margin and the finishing pass in one labelled block. A kit such as the Prima Crown Preparation Carbides Kit saves chair time and keeps margin geometry consistent case to case.

How can I tell the burs on Dentalkart are genuine?

Authenticity matters with burs because a copied diamond dulls quickly, needs heavier pressure and can shed grit into a preparation. The burs here move through each brand’s own supply line rather than a resale channel, and every blister and kit case is labelled with the shape, grit and pack size, so a clinic can match what arrives against the maker’s specification before it goes near a handpiece.
