Reliable tooling and reliable field support equals a reliable process. Using a mix of high-speed steel twist drills and various spade blades with limited success, our customer was looking for a reliable solution to drill a straight hole when machining HSK100A tool holder blanks in 4330 steel.
Wanting to stop scrapping parts and struggling with complete failures, the customer tested the T-A Pro drill. With the ISO-specific “P” geometry insert, ideal for improved tool life in steel applications, they were able to establish process reliability and drill straighter holes. On top of improving reliability, the T-A Pro significantly improved tool life.
Reliability isn’t just what we do; it’s who we are. Let us help you find the cutting tool solutions for your application.
