BORING BAR HOLDERS

WITH IMPROVED CLAMPING 

Why use Craftsman Tools' Boring Bar Holders?

The machining performance during a boring operation is significantly influenced by how the boring bar is held.

Developed in conjunction with major cutting tool and machine tool manufacturers, Craftsman Tools has developed a boring bar holder to improve machining performance.

The Craftsman Tools boring bar holder clamps the full circumference of the boring bar, rather than gripping on flats. This allows a better surface finish than standard boring bar holders, and enables machining at higher feed and speed rates.

Benefits offered by Craftsman Boring Bar Holders include:

  • 2.5x bar diameter clamping length and full radial clamping
  • Excellent vibration absorption properties
  • Backstop can be added to upgrade holder and provide through-coolant capabilities
  • Increased tool rigidity and improved cutting performance when boring
  • Ideal for high force/load applications
  • Coated bore and the inclusion of jacking screws make it easier to interchange boring bars
  • Reduction sleeves allow the holder to grip round tools and bars with smaller diameters
