Professional SVQBR/L Boring Bar for Internal Machining
The Internal Tool Holder - SVQBR/L (107,5°) by SMOXH is a specialized cutting tool designed for demanding profiling tasks within bores. Combining a defined 107.5° cutting angle with a precise seat for VBMT indexable inserts (VB.. 1103... and 1604...), this holding system provides excellent flexibility for internal contouring. The reliable screw clamping mechanism firmly secures the insert, supporting efficient workflows through quick insert changes and high repeatability. Featuring a solid body design without internal cooling holes, this boring bar proves to be highly robust and low-maintenance in daily industrial use.

Applications
This turning holder is primarily designed for internal profile turning and contour machining operations. The steep 107.5° approach angle offers great versatility when generating complex internal workpiece geometries, undercuts, and stepped bores. With its compact dimensions, suitable for minimum bore diameters starting at 21 mm, the tool holder is frequently utilized in precision engineering, general machine construction, and batch production on CNC lathes. The solid design without internal coolant channels makes it an excellent choice for dry machining environments or setups utilizing external coolant delivery.
Special features
The holding system stands out with a well-conceived structural design tailored to maximize the performance of positive VBMT inserts. The direct screw clamping minimizes the space required at the cutting head, which actively promotes unobstructed chip evacuation inside narrow bores. Furthermore, the available variants, ranging from 16 mm to 32 mm shank diameters, exhibit high structural rigidity, minimizing unwanted vibrations and contributing to consistent surface finishes.
