Welcome to Tool Supply Guy!

Collection: Turning & Boring

Tool Supply Guy supplies turning and boring tools for manual lathes, CNC turning centers, and boring machines. Our turning catalog covers single-point tool bits in square and rectangular shank cross-sections in 5% and 10% cobalt grades, high-speed steel, and micrograin solid carbide tipped configurations. Tool bit styles include neutral, right-hand, left-hand, and specialty nose geometries for external turning, facing, and profiling. Boring bars in steel and carbide provide internal diameter turning capability across short and long reach requirements. Specialty turning tools include box turning tools for supporting slender workpieces, back chamfering tools, and bump knurling tools for external knurl generation. Convex and concave radius tool bits cover form turning operations. Knurl wheels and knurl holders provide replaceable cutting elements for knurling setups. Whether you're doing production turning on a CNC center or toolroom work on a manual lathe, our turning catalog covers the tool geometries and material grades to match your operation.
