Knowing full well the importance of maintaining strict adherence to specifications, TOSCO port tools have been the flagship of TOSCO quality products. Every military or other industry standard is reflected in the construction and manufacture of TOSCO port tools. Each stocked port contour cutter will produce a finished product which will be exactly to specification. Extra quality for maximum re-sharpening is built into each TOSCO tool, plus such features as between-centers grinding for perfect concentricity. All of these details assure perfect one pass results. TOSCO engineers consider it their responsibility to build tools only one way—the right way! When you think port tools, there can be only one answer—TOSCO.

ALL TOSCO PORTING TOOLS ARE:

  • Ground between lapped centers to ensure concentricity
  • Manufactured with hardened steel bodies
  • In most cases, easily flute sharpened between centers
  • Meant to be returned to TOSCO for sharpen, regrind or retipping
  • Available for special applications with minor changes to specifications. Most standard Tosco porting tools can be altered for quick delivery. When major changes to design are made it is usually best to have TOSCO design and build a special-custom tool.
