Features

The tool offers the highest stability and length accuracy due to a special, ground profile connection on both ends between the tool body and insert holder.
An additional insert holder is available for each head size, providing an extended boring range and more chip space when roughing blind holes.
It includes a through-tool coolant supply, with adjustable coolant nozzles for sizes 53 and larger.
ISO standard inserts are available in various shapes and geometries, suitable for all workpiece materials.
The tool is designed for simple handling and features a compact design.

The Series 315 TWN twin cutter boring heads are designed for heavy-duty rough boring and semi-finishing operations.
Their compact, sturdy design and positive geometry allow almost chatter-free operation, even in interrupted cuts and at high cutting speeds.
Twin cutter boring heads can outperform single cutter finishing heads by a factor of up to 4 times.
Large stock allowances and high feed rates permit high production while assuring optimum bore roundness and location.
These features are critical for meeting today’s tighter control of part geometry.
In many cases, these tools can eliminate the need for semi-finishing cuts due to the superb balance of cutting forces, even under severe casting core shifts.
Rough Boring Heads TWN 315 series tools use ISO standard inserts with positive cutting geometry to reduce cutting forces.
The top clamp free mounting of the inserts and wide open chip spaces between the insert holders allow perfect chip formation and evacuation.
Different grades and geometries of carbide and silicon nitride inserts are available to optimize application criteria.
