• Ultra-precise .00005" steps of diameter corrections (.001mm on dia. for metric graduated heads) - without Vernier!



• High precision tool carrier locking system doesn’t influence diameter and assures the best repeatability.



• Integrated counterweight can be adjusted to any bore diameter by a separate scale to permit high speed operation.



• Four boring heads allow users to bore a range of .984" - 2.576" (25mm - 70mm).
  Not all sizes available yet, please call to check stock.



• All bore ranges and tool lengths are identical to existing Kaiser EWN program using Type 1 Insert Holders.

• Shorter projection means more rigidity for better performance.



• Dial adjustment of .0002"/div. with Vernier divisions to .00005" and large face dial means easy and precise adjustments at the machine.



• Fully compatible with existing 2-50XL heads to cover the range of .078" - 2.125" and 3.15" - 6.00" with existing standard components.



• Additional accessories allow for counter-boring, back-boring, chamfering and even O.D. turning.



• Available in CAT/BT40, HSK-A63 and CAPTO C6 shanks.

• Automatic balance for spindle speeds up to 30,000 RPM.



• Adjustment precision of .0001"/dia. with backlash-free micrometer spindle.



• Adjustment range: .106"/dia.



• Simultaneous clamping of adjustment cartridge and boring bar for high speed accuracy and rigidity.



• Through tool coolant supply to the cutting edge.

• Diameter range is covered with automatic precision balance by only two boring heads.



• Simultaneous clamping of adjusting cartridge and counterweight ensures precision accuracy and safe operation at high speeds.



• Forward and back boring applications are possible without the need for additional components.



• Large dial enables precision adjustments to be made at the machine.



• Hard coated surface for improved wear and scratch resistance.
