We have a lot of experience in extending the life of taps, reamers, and drills by applying Bellhammer to their cutting edges, while maintaining the jigs (stages and guides) with normal oil and grease.
(As an example, there is a drill whose cutting edge is usually damaged after 900 times of drilling and has to be replaced. (As an example, we have a drill whose cutting edge is usually damaged after 900 holes and has to be replaced.) When this drill is new, it can be drilled about 1600-1700 times by drilling two or three times into scrap metal with a bell hammer attached to the cutting edge at the beginning of the workday, at 10:00, after lunch, and at 15:00. This is a re-sharpening use of the cutting edge).
