For machinists and metalworking enthusiasts, a good parting tool is essential—and this set includes both the holder and the HSS blade you need. The holder is made from tough tool steel, heat-treated and ground to precise tolerances so it stays square and stable. It's got a nice epoxy-blackened finish to resist rust, and it's 3/4\ wide for solid clamping. The high-speed steel blade measures 3/32\ thick by 1/2\ wide by 4-1/2\ long, giving you a sharp, durable edge for clean cut-off operations. Changing the blade is easy since it uses a standard hex nut at the back (you'll need your own wrench or tap wrench). Whether you're working on a hobby lathe or a professional setup, this combo offers reliability and precision without breaking the bank. Just make sure it's compatible with your lathe's tool post, and you're ready to make clean, accurate cuts.
