Boring Bars

  • General-purpose boring for everyday diameters and materials.

Radial Relief
Boring Bars

  • Reduced contact for cleaner finishes and less rubbing.

Radius
Boring Bars

  • Blend radii and profiles without hand finishing.

Helical Back Rake Boring Bars

  • Improved chip evacuation and lower cutting forces.

Profile
Boring Bars

  • Complex internal profiles with predictable form control.

Mini
Boring Bars

  • Tight spaces and small bores without sacrificing rigidity.

Helical
Boring Bars

  • Balanced geometry for consistent performance across bores.

Back Chamfer
Boring Bars

  • Chamfer and deburr hard-to-reach features from inside.

CBN & PCD Tipped Boring Bars

  • High-wear applications and abrasive materials.

Helical Back Rake without Flat

  • Smooth entry and finish with a cleaner profile.

Helical Back Rake
with Flat

  • Extra stability and control where you need it.

Left Hand
Boring Bars

  • Left-hand orientation for setups that
    demand it.

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.
