Carbide Flame Cutters for Dental Labs by Busch

Carbide flame cutters are the dental laboratory's workhorse for shaping and trimming frameworks, acrylic, and models. Every cutter here runs on an HP (straight handpiece) shank, and the flame head gets into grooves, embrasures and undercuts that wider cutters cannot reach.

Choosing the Right Cut

• Super coarse and coarse cuts (425SG, 425SGX, 425G, 425GX, 425GXA, 425GQSR) — fast bulk removal on acrylic and model materials.
• Medium crosscut (425X, 425MQS) — balanced removal and finish for general framework and acrylic work.
• Fine and extra-fine crosscut (425FX, 425FFX) — smoother finishing passes on metal frameworks and detailed contours.
• SHORTIE (S430X, S430FX) — shortened cutters for better control and less vibration in close work.

Applications

Crown and bridge technology, plastics technology (dentures and appliances), model making, and model casting technique.

FAQ

What does crosscut mean on a carbide cutter? A crosscut (double cut) adds a second set of cuts across the blades, breaking chips into smaller pieces for smoother, lower-vibration cutting than a straight cut.

Are these for chairside use? No. These are HP laboratory cutters. For chairside composite finishing, see our Carbide Flame Finishing Burs.
