Overview
This turning kit is built for lathe work that calls for controlled cutting, threading, profiling, and cut-off operations. It combines hardened steel toolholders and high speed steel inserts, making it suited to slow-speed work and precision interrupted cuts on stainless steel, Inconel, Monel, exotic metals, and plastics. The square shank toolholders and boring bars are CNC machined from 4140/4142 steel bar stock, hardened, and finished with a black oxide coating. It is a practical setup for machinists who need a compact, purpose-driven tooling package with both right-hand and left-hand capability.

Pros
- Includes toolholders and inserts for turning, threading, profiling, and cut-off work.
- T-15 HSS inserts are hardened to Rc 65-67 and finish ground on all sides.
- Designed for slow-speed work, precision interrupted cuts, and a smooth finish on difficult materials.
- Square shank toolholders and boring bars are CNC machined from 4140/4142 steel bar stock.
- Toolholders and boring bars are hardened to Rc 48-50 and black oxide coated for corrosion resistance.
- Kit includes right-hand and left-hand bars plus a 3/8-inch shank boring bar.
Considerations & Trade-offs
- This kit is centered on slow-speed turning, threading, profiling, and cut-off work, so it is not the right choice if your setup or workflow depends on higher cutting speeds.
- The included boring bar has a .365" minimum bore requirement, which limits use on smaller-diameter bores.
- The package is purpose-built around the included holders and CEMW-2-1.5-1 inserts, so it is less flexible than a more general-purpose tooling setup.
- The description emphasizes performance on stainless steel, Inconel, Monel, exotic metals, and plastics, but it does not provide broader application details beyond those materials.
