Trusty-Cook personifies innovative spirit. Innovation began with our custom formula for polyurethane in the 1970s. Since then, millions of industrial tools have been made by others, and us, as a result of our trailblazing polyurethane efforts. Unlike the products of others, however, our products are always professional-grade tools and industrial accessories — dead blow hammers, polyurethane spindle liners, hush tubes for screw machines, and custom polyurethane parts for machines. At Trusty-Cook, we stick with what we know best and have perfected our mastery of the material over the years.


Jon Trusty, Senior, started the pioneering efforts of Trusty-Cook by introducing polyurethane dead blow hammers to the world in the 1960s. These hammers, made from Jon’s own formula and hot-cast polyurethane process, set such a high standard that Stanley Tools purchased the company from Jon in 1980. Trusty-Cook emerged in 1990 with a re-engineered hammer, once again staking a claim as manufacturer and private label supplier of the best dead blow hammers in the world.


The confluence of expertise and inventive thought drives Trusty-Cook’s expanded line of urethane products, including our spindle liners for CNC lathes. To call the polyurethane liner revolutionary might sound exaggerated to those who are unfamiliar with bar turning technology — but Trusty-Cook’s patented CNC lathe accessory allows machinists to manufacture parts from extruded profiles and odd shapes to the same exacting tolerances as parts machined from standard round stock. Our unmatched innovation, superior quality of products, and innovative engineered solutions will always remain top of the line.


From dead blow hammers to spindle liners, our urethane products are designed by experts and proven over time by professionals: our customers. At Trusty-Cook, you get what you order — all the way down to the expert molding, fit, and finish.

We take pride in being able to manufacture parts for special applications. While we have several thousand standard spindle liner parts in our database, it is our ability to manufacture spindle liners—and other accessories—for special applications that makes us different. And our solutions don’t end with accessories for machine tools. Our soon-to-be released line of Buddy Blaster hammers continues our history of innovation and creating solutions for customers.
