Rough Boring Holder Base

---

Rough Boring Holder Base

• 3 positions allows a single insert holder to bore the complete range
• Coolant directed onto the cutting edge for maximum cooling, chip forming and tool life
• Independent height and diameter setting permits balanced cutting with production of almost perfectly round holes from the beginning, irrespective of core shifts.
• Two height balanceable cutting edges results in metal removal at rates almost 4 times that of a single cutter.
• Height adjustments are made with a cam that supports the insert holder where needed, at the furthest radial point.
• Each insert holder can be adjusted individually in diameter with a dial screw for fast, easy set-up operations.
• Balanced or stepped cutting can be done with the same set of insert holders permitting heavy stock removal and eliminating the need to purchase two sets of insert holders.
• Standard through-spindle coolant capability cools the insert and flushes chips.
• ISO standard inserts – requires no special expensive inserts.
• Square SCMT insert holders with 6° lead for through hole boring or extreme core shifts.
• Diamond CCMT insert holders for boring to a square holder, or deep bore lengths.
• Trigon WCMT insert holders for applications requiring heavy stock removal.
