BIG Kaiser Precision Tooling Inc. introduces a patent-pending new series of Kaiser boring tools. The new series has adjusting resolution of .001mm steps of diameter corrections (.00005” on dia. for inch graduated heads). This allows users to easily make fine incremental adjustments where critical diameter tolerances are required – and without the use of a Vernier scale.

Heads offer reader-friendly dials and backlash-free tool carriers for direct diameter adjustment. The high precision tool carrier locking system does not influence diameter and assures repeatability, even under high speed or interrupted cutting.  The series’ six boring heads allow users to bore a range of 20-100mm (0.787”-3.94”).  Kaiser's 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.
