Nechamkin Chasing Tools are formed from solid W1 tool steel using old fashioned machinery and skilled hand shaping. The tips are heat-treated in a controlled environment to ensure consistent Rockwell hardness. The 4.25” (108mm) long shanks are square for precision and control superior to that of round. They have chamfered corners and a satin finish for comfort in hand. Each chasing tool is numbered for easy identification. All tool faces are precisely shaped and polished in a manner which allows them to travel smoothly across metalwork. For excellent sight down to the working face, tapers are long and balanced. The durable stainless steel container, an added value, is designed with room for augmentation of your tool set and has a non-marking Delrin™ lid and bottom.
