PINZBOHR modular boring system is composed basically of 3 different designs of boring heads and all its couplings and accessories. The whole of this system allows boring holes in a range that goes from 6 mm. up to 500 mm.

PINZBOHR has 3 basic designs:

1. Rough boring head (fitting two carbide insert)

2. Finish boring head (fitting one carbide insert)

3. Micro boring head - for small diameters - (fitting indexable boring bars with carbide insert pockets)

All of these heads are radially adjustable to produce different bore diameters. Micro and Finish boring heads have a graduated precision dial readout to 0.002 mm. Rough boring heads are twin radially adjustable by means of a spindle that moves simultaneously two slides with insert pockets.

PINZBOHR couplings are where the heads are mounted. These couplings are available in several executions to suit the most popular machine spindles, you'll find: MAS BT, DIN 69871.1 (ISO 7388/1/3), ISO Standard DIN 2080, Morse, HSK, Weldon (DIN 1835), etc.

As accessories, PINZBOHR features Reducers, Extensions, coolant through Extensions and adapters for the assembly of large boring heads.

As modular system, PINZBOHR features adaptors to match PINZBOHR couplings with standard face Milling Cutter holders, Weldon, Morse and adaptors for Drill Chucks (DIN 238).

Chamfering heads with 45º angle approach can be fitted on the PINZBOHR couplings axially positioned at your best convenience.

Indexable cartridges are mounted on Finish and Rough boring heads from size 68 mm. up to 500 mm. and feature several combinations for customer's choice like different insert geometries and different angle approach (75º or 90º). Cartridges also have an additional radial adjustment on the slide body.
