AI Technical Summary

Benefits of technology

The technology described in this patented solution allows for better precision during processing steps like tapholes through use of only one drilling machine instead of multiple machines or requiring repetitive installations with each other. This results in more precise holes being created without repeating them again later on.

Problems solved by technology

The technical problem addressed by this patented method relates to incorrect placement or positioning of tools during turning operations due to misalignment between various types of drilling devices such as drills that have been mounted on an adapter plate. This can lead to poor quality hole processing results if there were any issues later caused by these improperly placed drillbits.

Abstract

The invention relates to a step drill, which comprises a drill body and a drill stock, wherein the drill body is stepped and at least comprises a first cutting part and a second cutting part; the first and second cutting parts are coaxial; the first cutting part is positioned at the front end of the drill body; the second cutting part is positioned behind the first cutting part; the diameter of the first cutting part is less than that of the second cutting part; each cutting part is at least provided with two helical cutting blades; a chip groove is formed between every two cutting blades; and an end face cutting blade is formed at a transition part between the second and first cutting parts. A stepped hole can be machined with one such step drill, which prevents errors caused by the repeated installation of a drill bit and improves the machining accuracy of the stepped hole.
