The P variety is suitable for all ISO indexable inserts. There are no loose parts and only a few spares are required, making them easy to handle. Inserts can be clamped quickly and securely and released easily. Chip flow is smooth, as there are no obstructions.
The S toolholders also enable the insert to be secured simply and safely, in this case using a cone-shaped positioning screw. Here too, chip flow is not compromised and a maximum of three spare parts is needed. In both cases, coolant is supplied as standard at the back of the shank end; optionally from below the head.
This move follows the joint cooperation between Horn, Germany, and Boehlerit, Austria, that sees each company sell the other's tooling.
