Kennametal B-1112 Carbide Indexable Boring Bar Insert

Kennametal B-1112 Carbide Indexable Boring Bar Insert is a carbide, replaceable cutting insert designed for internal-boring operations in metalworking. The B-1112 variant is listed with a TP-32 interface and a 12" shank, indicating its mounting compatibility within Kennametal’s boring-bar tooling ecosystem. Made from carbide, the insert provides high hardness and wear resistance to help maintain precise bore diameters and smooth surface finishes when used with a compatible boring bar holder. As an indexable insert, worn cutting edges can be rotated or replaced, enabling continued cutting performance without replacing the entire boring bar assembly. This item is intended for use with Kennametal boring bars that accept TP-32 inserts and is suited for internal boring tasks where accurate bore sizes and consistent finishes are required. In practice, technicians select an appropriate B-1112 insert to achieve the desired bore tolerance on workpieces, then index the insert as edges wear. The TP-32 interface design supports secure seating and repeatable alignment within compatible tool holders, supporting reliable performance across multiple runs. Always verify machine compatibility and follow Kennametal’s mounting recommendations to ensure correct seating and cutting performance.
