KeenKut Products has been in business for over 70 years.  Mr. Ralph Arnold founded Keen Kut in 1947.  Ralph was the innovator of small diamond core drills as we know them today.

Frank and Dee Lenner, the previous owners, were with the company for over 34 years and dedicated and succeeded in making Keen Kut one of the leading manufacturers in the industrial diamond field.

Hung and Barbara Le, the current new owners both have over 10 years of experience working in different manufacturing companies throughout California.   We are now following our dream of owning our own machine shop by acquiring Keen-Kut Products and are committed to providing and upholding the quality of the products that we offer.

We are dedicated to keeping Keen-Kut a recognizable name in the industry by continually providing high quality products, constantly innovating our techniques and continuously improving our technology.

Keen Kut is located in the San Francisco Bay Area and services a world-wide community.
