Cutting tool having a cutting cartridge adjusted by a turning key engageable with a serration of the cartridge

摘要

A rotary metal-cutting tool includes a tool body and a cartridge carrying a cutting insert that is adjustable in relation to the tool body. The adjustment is accomplished by providing a serration on one side surface of the cartridge and a correspondingly curved recess in the tool body adjacent the serration for the receipt of a key element. The key element has teeth engageable with the serration such that rotation of the key produces adjustment of the cartridge and insert.
