Since 1950, Wetmore products are known for precision, balance and serviceability. Our production team in our Chino, California facility have a "can do" attitude to meet the most stringent needs of our customers. From simple cutting tools to complex, our teams have the technology and experience to service the aerospace, automotive, fastener and metal working industries. We specialize in drills and cutting tools made to NAS 897, 907, 937 and 965 standards.


Our company started as H.P. Manufacturing in 1950 in California and has added additional value to our offer over the years. Over the years, we have elevated the Wetmore brand to be our signature go-to-market product for specialty aerospace cutting tools, as the company evolved into Wetmore Tool and Engineering.
In 2019, Wetmore Tool and Engineering was acquired by Dormer Pramet. As part of our company integrations, the Wetmore brand logo has been updated to align with all other Dormer Pramet cutting tool brands. While the company is now Dormer Pramet, the Wetmore brand of aerospace and specialty cutting tools continues on as the leader in its industry.
Wetmore products include carbide tipped rivet shavers, specialty reamers, threaded shank adapter drills, core drills, double-margin step drills, nutplate drills and special application drills and reamers.
All Wetmore products are Made in the USA at our ISO 9001 certified facility in Chino, CA.
