Improved Twin Cutter Boring System

New BIG Kaiser series has reversing insert holders for alternate cutting methods

The corrosion-resistant 319 SW series boring heads use standard carbide inserts (CC, SC, and SP) and provide coolant-through direct to the cutting edge.

BIG Kaiser Precision Tooling, the developer of high-precision tooling systems, is offering a new twin-cutter rough boring system. The 319 SW series are described as “exceptionally rigid,” corrosion-resistant boring heads that offer an unusual design feature: by reversing the insert holders users can switch between balanced and stepped cutting.

BIG Kaiser Precision Tooling is a family of tooling product that includes the Kaiser, BIG Daishowa, Speroni, Unilock, and Sphinx brands, among others. The group claims its designs are developed with a focus on accuracy and repeatability.

The new Kaiser 319 SW series replaces its previous 314 RW series. Because there is no need to resort to additional components or to adjust insert height manually for different roughing methods, the 319 series reduces setup time and eliminates the need for a presetter due to fixed tool heights and a diameter scale on the tool.

“These tools are fully compatible with our existing KAB and CKN modular systems and offer much larger variety, versatility and capability to our rough boring program,” stated Jack Burley, BIG Kaiser v.p. - sales and engineering. “Although the current 314 series will be phased out, our customers will maintain the same roughing methods from one head using the 319 program, but now with greater ease of setup and higher performance.”

The tools, with a diameter range 0.787-8.000 in., use standard carbide inserts (CC, SC, and SP) and provide coolant-through direct to the cutting edge, to improve chip evacuation and lengthen tool life.
