The Groz Knurls are precision cutting tools used to produce knurled patterns on workpieces. They are made of high-speed steel, fully hardened to a Rockwell hardness of 60+ HRC, ensuring durability and longevity. The short teeth on these knurls are perfectly formed, while the faces are chamfered on both sides to produce burr-free work of uniform precision. 

These knurls come in both left and right-handed designs, allowing for the creation of both left and right-handed knurled patterns. To produce diamond knurling, a pair of right and left-hand knurls must be used together. These high-quality knurls are ideal for various knurling applications and will provide reliable and consistent results for the professional user
