EXPERT OPINION This kit was built around how we actually prepare teeth, not around what is easy to manufacture. Every bur has a defined role, and the medium/fine pairing philosophy is deliberate: medium grit for initial reduction, fine grit for refinement before impression. Swapping between them at the right stage protects the preparation surface and gives your technician a clean result to work with. Several burs here — the short-shank cylinders (C-27, C-28) and the controlled margin bur (C-11) — were specified to our own dimensions and are not standard Frank Dental catalogue items. The Bur Stand Designed & manufactured by Incidental — 30 holes, fully autoclavable Holds the full kit with spare slots for your own additions. The open-hole design means you can autoclave burs seated in the stand with no decanting required. Numbered positions make reordering individual burs straightforward — download the wall chart below and pin it up. The Burs The kit contains one of each of the following. All burs are available to purchase individually. C-1 — Rugby Ball Bur, Fine Grit (D.379.021.F.FG) | Max 225,000 RPM The rounded rugby ball profile is the preferred shape for fine finishing of marginal ridges and onlay margins. Use after your medium-grit reduction to clean up margin geometry before impression. C-2 — Occlusal Shaper, Medium Grit (D.370.030.FG) | Max/Optimum 100,000 RPM The undulating profile mirrors natural occlusal anatomy for anatomically sympathetic reduction in cuspal-coverage restorations. Medium grit makes this the first-pass occlusal bur. C-3 — Occlusal Shaper, Fine Grit (D.370.030.F.FG) | Max 100,000 RPM / Optimum 20,000 RPM Identical geometry to C-2 in fine grit. Run after C-2 to unify the occlusal surface and eliminate coarse striations. The optimum speed of 20,000 RPM allows controlled finishing without overheating. C-4 — Large Ball, Medium Grit (D.801.035.FG) | Max 225,000 RPM Primary bur for palatal surface reduction on upper incisor crown preparations — prepare half the tooth at a time to gauge reduction accurately. Also useful for occlusal reduction when the Occlusal Shaper cannot achieve the correct angulation. C-5 — Wheel Bur, Medium Grit (D.909.040.FG) | Max 225,000 RPM The flat-sided wheel profile produces effortlessly level incisal reductions during crown and veneer preparations. Also serves as an alternative to the large ball bur for palatal reductions. C-6 — RA Mandrel For use with the Tor VM polishing disc range at slow-speed contra-angle. Useful chairside for smoothing preparation surfaces and refining provisionals. C-7 — End Cutting Bur, Fine Grit, 1.2mm (D.839.012.F.FG) | Max 225,000 RPM Smooth sides, cuts only at the tip. The correct instrument for safely smoothing bumps, lips, or ledges on a finished margin without widening the preparation wall. Also useful for removing deep core material below the margin line. C-10 — Depth Cutter, 1.5mm (D.824.009.FG-1.5) | Max 160,000 RPM Produces a precisely uniform 1.5mm occlusal depth cut in a single pass — the minimum reduction typically required for lithium disilicate. Removes reliance on visual estimation. C-11 — 0.4mm Controlled Margin Reduction Bur, Coarse Grit (D.881.010.FG) | Max 280,000 RPM Produces a controlled 0.4mm rounded shoulder by sinking the bur until the safe-end guide tip contacts the tooth, then sweeping around the preparation. Keep the bur upright — any tilt compromises the uniform margin depth. C-12 — 0.4mm Tapered Depth Cut Bur (D.Z868B.020.FG) | Max 160,000 RPM Creates controlled 0.4mm facial depth grooves for veneer preparations, ideally through a bisacryl pre-evaluative temporary following the Gurel protocol. The 1.5mm rounded tip also gauges occlusal depth grooves during posterior preparations. C-13 — Endodontic Safe-End Access Bur, Tungsten Carbide (C.269GK.016.FGXL) | Max 160,000 RPM Safe-ended TC bur for pulpal wall removal during endodontic access, and equally effective as a large batt bur for vertical crown preparations where access permits a wider instrument. C-14 — Needle Bur, Medium Grit, Long (D.859.012.FG) | Max 225,000 RPM The extended diamond portion — longer than most catalogue equivalents — gives better interproximal access for contact point breaking during crown preparations. C-15 — Thin Flame, Medium Grit (D.8862.012.FG) | Max 225,000 RPM Included primarily for BOPT vertical crown preparations, where the thin flame profile gives excellent proximal access for initial cutting passes. Also useful for general proximal margin refinement. C-16 — Thin Flame, Fine Grit (D.862.012.F.FG) | Max 225,000 RPM Fine-grit counterpart to C-15. Use after C-15 to eliminate coarse surface texture on proximal walls and margins in BOPT preparations. C-17 — Thick Flame, Fine Grit (D.862.016.F.FG) | Max 225,000 RPM Larger diameter flame for facial and lingual surface refinement in BOPT preparations. Fine grit produces a clean, consistent surface texture prior to impression. C-18 — Thick Flame, Medium Grit (D.862.016.FG) | Max 225,000 RPM Medium-grit counterpart to C-17 for initial facial and lingual reduction in BOPT preparations. The wider body removes tissue efficiently before C-17 refines the result. C-19 / C-20 — 1.0mm Taper Batt Bur, Medium & Fine Grit (D.851.010.FG_E / D.851.010.F.FG_E) | Max 225,000 RPM Non-end-cutting design safely prepares a knife-edge margin without risk of inadvertent apical extension — essential for edgeless and vertical crown preparations. C-19 (medium) for initial definition, C-20 (fine) to refine. C-21 / C-22 — 1.2mm Taper Batt Bur, Medium & Fine Grit (D.851.012.FG_E / D.851.012.F.FG) | Max 225,000 RPM The wider 1.2mm diameter provides slightly more body to the margin geometry than the 1.0mm pair — useful where a more substantial knife-edge profile is required. Same non-end-cutting safety principle. C-25 / C-26 — 1.0mm Round-Ended Cylinder, Medium & Fine Grit, 8mm (D.881.010.FG / D.881.010.F.FG) | Max 225,000 RPM Our recommendation for classic crown preparations — the round-ended cylinder naturally produces a rounded shoulder margin. The 1.0mm diameter is particularly valuable for proximal surfaces with limited access. C-27 / C-28 — 1.2mm Round-Ended Cylinder, Short Shank, Medium & Fine Grit (D.881.012.FGS / D.881.012.F.FGS) | Max 225,000 RPM Custom-specified with a shorter shank than the standard Frank Dental catalogue. Sitting deeper in the handpiece chuck meaningfully improves access for difficult posterior or lingually-positioned preparations. Not available as a standard catalogue item. C-29 / C-30 — 1.4mm Round-Ended Cylinder, Medium & Fine Grit (D.881.014.FG / D.881.014.F.FG) | Max 225,000 RPM The 1.4mm width is indicated for accessible surfaces and where a deeper margin is required — PFM preparations being the classic example. The broader profile removes more material per pass for efficient wider shoulder preparation. Download the Indirect Bur Kit Wall Chart — for easy organisation and reordering
