SW BIG CAPTO Rough Boring Head

June 02, 2021
One-Piece Body Provides for Highly Repeatable Accuracy and Torque Transmission

BIG KAISER Precision Tooling, a global leader in high-performance metalworking equipment, has introduced the Series 319 SW rough boring head with the BIG CAPTO connection. The new SW BIG CAPTO Rough Boring Head makes it possible to perform rough and finish boring processes seamlessly with the finishing heads it has offered for years. BIG KAISER currently offers the widest range of rotating BIG CAPTO tooling of any provider. 

In accordance with ISO 26623-1, the polygon shape of the taper and one-piece body construction provides for highly repeatable accuracy and torque transmission, an ideal fit for rough boring work. The SW BIG CAPTO achieves high repeatability, in part, thanks to the flush fit of the polygon taper with the spindle. The combination of a self-centering 1:20 taper and the long taper edge ensures stable runout accuracy.

The SW BIG CAPTO is available in sizes C3, C4, C5, C6 and C8. The diameter range is ø.984"-8.000".

Boring is essentially internal turning, in that usually a single-point cutting tool forms the internal shape. Some tools are available with two cutting edges to balance cutting forces.

  • boring head

    boring head

    Single- or multiple-point precision tool used to bring an existing hole within dimensional tolerance. The head attaches to a standard toolholder and a mechanism permits fine adjustments to be made to the head within a diameter range.

  • metalworking

    metalworking

    Any manufacturing process in which metal is processed or machined such that the workpiece is given a new shape. Broadly defined, the term includes processes such as design and layout, heat-treating, material handling and inspection.
