Rotary instruments for the dental practice come in eight types. Which one you need depends on the material you are working on and on the handpiece the instrument goes into. This page sorts 1,764 items by exactly those two questions.
1,764 burs in stock, ready to ship in 48 hours. Swiss made, ISO 13485 and CE-MDR.
| Task | Instrument | Why this one |
|---|---|---|
| Caries removal | Round bur, excavator | Cuts soft dentine in a controlled way without taking healthy tissue |
| Cavity preparation | Diamond bur | Abrasive and true to shape, clean cavity walls |
| Crown preparation | Diamond bur, coarse to fine | Bulk removal with coarse grit first, finish with fine |
| Zirconia and all-ceramic | Diamond bur for zirconia | Stronger bond, stands up to the harder material |
| Finishing a filling | Finisher | Cuts without grooves, prepares the polish |
| Amalgam removal | Carbide bur | Cuts the metal instead of smearing it |
| Crown sectioning | Crown cutter | Cuts through metal and ceramic in one pass |
| Osteotomy | Lindemann bur | Cuts at the tip and laterally, low heat build-up |
The difference is fundamental: a diamond instrument grinds, a carbide instrument cuts. Diamond removes material through countless bonded grains and leaves a rough, defined surface. Carbide works with blades like a milling cutter and leaves a smoother finish.
Use diamond for enamel and ceramics, because these materials are hard and brittle. Use carbide for dentine, amalgam, composite and bone, because a blade works more cleanly there than a grain that clogs.
The shank decides whether the instrument fits your handpiece at all. The number sits at positions four to six of the ISO code.
| Code | ISO | Drive | Items |
|---|---|---|---|
| FG | 314 | Turbine | 1,062 |
| HP | 104 | Straight handpiece, lab | 299 |
| RA | 204 | Contra-angle | 155 |
| FGL, FGXL, FGs | 313, 315, 316 | Turbine, special lengths | 191 |
| RAL, RAXL | 205, 206 | Contra-angle, long | 50 |
ISO 6360 describes the instrument in blocks: digits 1 to 3 the material, 4 to 6 the shank, 7 to 9 the head shape, 10 to 12 the grit or cut, and 13 to 15 the working part diameter in tenths of a millimetre. So 806 314 001 524 018 reads as: galvanic diamond, FG shank, round, medium grit, 1.8 millimetres.
By the colour ring on the shank. Black and green mark coarse grits for bulk removal, blue without a ring the standard grit, red and yellow the fine grits for finishing. The scheme is standardised and identical across manufacturers.
That depends on the instrument and the material worked, not on a fixed number. Cutting performance is what counts: as soon as an instrument needs more pressure or takes longer, it generates more heat and should be replaced. Carbide instruments dull far faster on ceramics than on dentine.
Turbine instruments with an FG shank run at high speed with water cooling. Carbide burs in surgery run considerably slower, because bone is damaged from around 47 degrees. The exact ranges are on the respective category pages and in the data sheets.
As a rule, yes. The ISO number describes shape, shank and size independently of the manufacturer. If you know the number of your current instrument, you will find the equivalent here.
