Porting Tools
Cut Ports that Seal Right the First Time
You need clean, consistent ports that meet spec and hold pressure. Scientific Cutting Tools designs solid carbide and carbide‑tipped port tools with polished flute faces for smooth finishes, excellent chip control, and repeatable accuracy. Many tools are available with coolant‑through designs and a variety of coatings are available to extend tool life in challenging materials.
