Introducing the Knurling Tool Set, consisting of two high-quality tools designed for precision knurling tasks on various lathes. Knurling Tool #1: This adjustable H-type, spring-loaded clamp knurling tool is built for versatility. With a maximum capacity of 2" (50 mm), it features a 3/8" square shank x 3-1/8" long. The knurl dimensions are 3/4" (diameter) x 3/8" (wide) x 1/4" (hole), ensuring sharp, consistent knurls. A unique design includes a spare smaller rod and extra spring, allowing you to reduce the tool's capacity by re-bolting the knurling arms into lower inner holes, offering greater flexibility. Knurling Tool #2: This sturdy V-clamp type knurling tool can be easily mounted on the standard holder of quick-change tool posts and is compatible with lathes like Myford, Boxford, and ML7 Series, as well as other similar-sized machines. It has a knurling capacity range of 5-20 mm, with a holder size of 3/8" x 3/8" x 2-1/4". The tool is paired with left and right hand medium pitch diagonal line knurls to create a precise diamond texture. Knurl dimensions are 3/4" x 3/8" x 1/4" (bore). Both tools are made from durable tool steel, with knurls crafted from EN31-grade tool steel, hardened to 52+/-3 HRC for long-lasting durability. This set includes 2 extra pairs of knurls, providing even more value for various knurling applications. Perfect for machinists and hobbyists alike, these tools enhance efficiency, precision, and reliability for any lathe-based knurling project.
