Original Abstract

Tool material HSS is used for drills forming. The supplied material has enclosed from two separate batches the same certificate from the manufacturer. The material is in the standard CSN 419830. From one batch can be produced drills from the second cannot be produced. The article discusses the detailed analysis of the material. The differences are shown that are not listed in the attestation. Tests were performed for the customer available. Tests are not time consuming. Customer engaged in mass production usually does not have the possibility to detect differences. The customer usually does not have the necessary equipment. Made and recommended tests are based on metallographic knowledge, including hardness measurements, qualitative and quantitative chemical analysis. Data have graphical output. Elements are compared from the viewpoint of influence on hot formability. According to these collected data, the customer can assume the subsequent success of the production process.

Keywords
