A780 and A790 radial type heads Boring Holemaking

The radial type of fine boring heads consist of two ranges:
  • A780, a range of 9 pre-balanced, fine boring heads covering a diameter range of 15 - 205mm (.59 to .72 inches).
  • A790, a range of 5 balanced fine boring heads designed for high speed machining in the 30 - 115 diameter range.

The main benefits of the A780 and A790 radial type heads are:

  • Precision
    - Micrometric adjustment within 2.5 µm on the diameter
    - Micrometric diameter setting protected by the insert holder and head contact
    - Hole diameter precision IT5 is possible to achieve
  • Productivity
    - Cutting speeds up to 1500 m/min with balanceable heads
    - Coolant through the head towards the insert
  • User friendly
    - A790 balancing rings with direct setting - no balancing charts needed
    - Insert holders for chamfering and back boring
  • Cost effective
    - For low to average machine speeds, pre-balanced heads are ideal
    - All heads use only three insert holder sizes
  • Long tool life
    - All A780 and A790 type heads are dust proof and greased for life - no re-greasing maintenance is required.
  • Flexibility
    - Large range of insert grades for all materials
