Busch Laboratory Bur Exclusives

Busch laboratory bur exclusives are the rotary instrument lines that Busch & Co. of Engelskirchen, Germany, developed specifically for the dental laboratory: KERA ceramic cutters (K-series), the ZIRKON Workflow Set (No. 5440), MIDI (M-series) and SHORTIE (S-series) carbide cutters, left-handed cutters, DiaTwister diamonds (DT-series) and the 911PS diamond saw for plaster models. They are used for cutting, contouring and finishing acrylics, zirconia, ceramics and plaster in laboratory work. Each line is described below with a link to its own collection.

KERA Ceramic Cutters: These lightweight, all-ceramic instruments (up to 60% lighter than traditional carbide) deliver exceptional hardness, fracture toughness, and vibration-free cutting. Ideal for finishing and contouring dental acrylics, shape corrections on zirconia blanks, and precise work on plastics. Their aesthetic design and sterilizable construction provide outstanding control and longevity for laboratory technicians. See KERA Ceramic Cutters
ZIRKON Workflow Set (5440): A comprehensive 23-piece set (plus polishing paste) designed for efficient zirconia processing from pre-sintered stages to high-shine polishing. It streamlines the workflow into clear steps, ensuring precise restorations with minimal effort and optimal surface quality. Perfect for modern digital dentistry labs focused on zirconia restorations. See ZIRKON Workflow Set
Busch MIDIs: These mid-sized rotary instruments offer a balanced length and power for versatile laboratory tasks. They provide reliable cutting performance and control in applications requiring more reach or torque than standard short burs, making them essential for efficient material removal and shaping. See Busch MIDIs
Busch SHORTIEs: Compact and maneuverable, SHORTIEs excel in tight spaces and detailed work. Their shorter shank design enhances precision and access for intricate contouring, finishing, and adjustments in dental lab procedures, reducing fatigue during prolonged use. See Busch SHORTIEs
Left-Handed Cutters: Specifically engineered for left-handed users, these carbide cutters (available in X and FX cuts, multiple shapes and ISO sizes) enable ergonomic, anti-clockwise rotation toward the body. They deliver smooth, efficient performance while improving visibility, comfort, and safety—promoting better workflow for all technicians. See Left-Handed Cutters
DiaTwister: These innovative diamond instruments feature an open, slit-designed structure that prevents overheating during acrylic and plaster processing. They ensure cool, comfortable operation (dry or wet) with superior finishing results, making laborious tasks faster and preserving material integrity. See DiaTwister
911PS for Plaster Models: This diamond-coated, perforated circular saw creates clean, precise saw-cut models in all classes of plaster. Its design facilitates easy separation and high-quality results for diagnostic and working models. See 911PS for Plaster Models

Which Busch Laboratory Exclusive Do You Need?

Pick the line first — ceramic (KERA) for acrylics and zirconia shape corrections, MIDI or SHORTIE carbides by the reach you need, left-handed cutters if you work anti-clockwise, DiaTwister diamonds for cool-running acrylic and plaster work, and the 911PS saw for plaster models — then the shape and size. Every active instrument in the collection is listed once below; all are HP (2.35 mm) shank.

Laboratory Use

These lines cover the laboratory workflow from cutting and contouring acrylics and plaster to shape corrections on zirconia blanks and ceramic finishing: carbide and ceramic cutters for material removal and contouring on the straight handpiece, DiaTwister diamonds where heat build-up on acrylic or plaster is the concern, and the ZIRKON set for the stepwise processing of zirconia restorations. Observe the recommended speed for each instrument type — see our Dental Bur Speed Chart.

Care and Reconditioning

Laboratory rotary instruments are reusable: clean them after use and store them dry so the cutting surfaces stay sharp. Our Dental Bur Reprocessing & Sterilization Guide covers cleaning and sterilization for Busch rotary instruments.
