Hertel Mts 183 Torx Insert Screw Indexable Boring Bar

Product Description

The HERTEL MTS 183 is a Torx-drive insert holding screw designed for indexable cutting tools used in boring bar applications. This hardware component secures replaceable carbide inserts within C Series toolholders, maintaining precise insert positioning during machining operations. The screw features a Torx drive interface, which provides improved torque transfer and reduces the risk of cam-out compared to hex drives. At 0.05 pounds, it is a lightweight fastener intended for use with inserts in the 0.156-inch inscribed circle range. Installation is performed by machinists and tooling technicians as part of routine insert indexing or replacement in turning and boring setups.

The MTS 183 is suited for use in boring bar toolholders following the C Series style. It is compatible with CDHB and CDHH series inserts, making it appropriate for internal turning and boring operations on CNC lathes and machining centers. This screw is a direct hardware replacement used during standard insert change intervals on the shop floor or in tool crib maintenance.
