3.175x10xR0.5 radiused bottom engraving bit is a solid carbide precision cutter developed for fine three-dimensional relief, rounded grooves and detailed CNC engraving. Its radiused cutting tip blends surfaces smoothly while the tapered profile adds rigidity for controlled, accurate carving.
Applications: Acrylic, PVC, MDF, hardwood, density board, plastics and suitable non-ferrous materials. It is ideal for relief carving, lettering, curved channels, fine modeling and finishing.
Features: Ultra-fine tungsten carbide construction, precision-ground geometry, sharp polished cutting edges, stable chip evacuation and excellent wear resistance. The radiused bottom helps reduce visible tool marks on contoured surfaces.

3.175x10xR0.5 Radiused Bottom Engraving Bit Performance
Use a clean, correctly sized collet and keep tool overhang short. Match spindle speed, feed and pass depth to the material and machine rigidity. A shallow finishing pass provides the smoothest relief surface and longest tool life.
