What You Get With SCT
Size control you can trust
Hold size and position with boring bars designed for stability and repeatability. When offsets matter, you want predictable engagement and consistent results from the first part to the last.
Better finishes with less rubbing
Choose geometries that reduce contact and control how the tool enters and exits the cut. The result is cleaner wall finishes, less chatter, and fewer “mystery marks” that show up at inspection.
Chip control that keeps production moving
From helical and back-rake options to relief styles, these tools are built to manage chips and reduce cutting pressure. That means fewer interruptions, more confidence at higher feed rates, and more consistent cycle times.
