Elk Grove Village, IL - BIG Kaiser Precision Tooling Inc. introduces a truly revolutionary and patent-pending new series of Kaiser boring tools. The new series has the distinction of the finest adjusting resolution - .001mm steps of diameter corrections (.00005" on dia. for inch graduated heads). This innovation will allow users to easily make fine incremental adjustments where critical diameter tolerances are required - all without the use of a Vernier scale!

The EWB UP series sets a new standard for diameter adjusting accuracy, while still possessing Kaiser's worldwide reputation for the highest precision and repeatability of any boring tool system. These heads offer easy-to-read dials and backlash-free tool carriers for direct diameter adjustment. The high precision tool carrier locking system doesn't influence diameter and assures the best repeatability, even under high speed or interrupted cutting.

The series' six boring heads allow users to bore a range of 20-100mm (.787"-3.94"). The flexibility of the Kaiser KA connection permits a wide range of spindle interface options. All bore ranges and tool lengths are identical to existing Kaiser tools. The integrated counterweight can be adjusted to any bore diameter by a separate scale to permit high speed operation.
