In recent years Craftsman Tools has developed a range of machine adapted tool holders specifically for deep hole boring using on a lathe.

Our holders offer compatibility with anti-vibration bars and are ideal for high force/load applications. Working together with the Silent Tools® and Steadyline™ typically allow for a boring depth of up to 14 times bar diameter.


  • Compatibility with both Silent Tools® and Steadyline™ anti-vibration boring bars. Excellent vibration absorption properties.
  • 4x bar diameter clamping length and full radial clamping increases tool rigidity and improves cutting performance. Ideal for high force/load applications.
  • Suitable for boring up to 10x the bar diameter in depth (with 14x diameter lenght bars)
  • Range available for all of the major Machine Tool Manufacturers, including Mazak, Doosan, Mori Seiki, Okuma.
  • Available with through-tool coolant feed via removable backplate.
  • Moly-coated bore and the inclusion of jacking screws (hinge type only) make it easier to interchange both tools and reduction sleeves.
  • Craftsman Tools reduction sleeves allow the holder to accept tools smaller in diameter
  • Many holders offer larger bore sizes than the standard holders


  1. INCH / METRIC TOOL SIZE - "A" : Inch style / Blank : Metric
  3. TOOL SIZE - For example 2 = 2 inches, 50 = 50mm
  4. MACHINE MODEL - LB4000EXM = Okuma LB4000EXM
  5. REFERENCE DIMENSION - Gauge line from turret face to centre line of boring bar (mm)


Our range is designed as one of two clamping variants. Where  feasible a single piece Hinge-Style will be used, however the interfacing bolt pattern and required tool size often means a 2 piece Cap-Style has to be used. Both styles of holder will accept split reduction sleeves and are suitable for 10 x diameter boring applications.

Cap Style

Hinge Style


The same holder can clamp a range of boring bars by using reduction sleeves.

Features include:

  • Combined captive spacer maintaining 4 x diameter clamp length
  • Easy withdrawal of both sleeve and spacer
  • Aligned in the holder for ease of setting


A full range of standard Reduction Sleeve are available on the accessories page
