# Tool and manufacturing method of it

## Abstract

A tool includes a cemented carbide part and a steel part joined by brazing, where the steel part has an average hardness of between 390 and 510 HV30. The braze joint includes Ti and a TiC layer, with a thickness of between 0.03 and 5 μm, adjoining to the cemented carbide part. The tool provides a strong braze joint and a steel part that have an even hardness.
