Use Micro 100 Solid Carbide Tool Holder to Fix that Boring Bar in Place. Boring is a cutting operation to enlarge an existing opening in a workpiece using a single-point cutting tool. Boring tools are connected to milling machines, lathes, or other machines using boring heads and holders. Boring heads hold boring bars for enlarging holes. Ultimately, boring head holders consisting of these boring heads are attach to milling machine spindles or a lathe or turning machine. Tool holders are almost as equally important as the tool itself. It is the intermediate between the cutting action and the machine's spindle and thus integral for overall performance. Any tool holder type must have offer high-speed clamping force, as well as reduced vibration runout accuracy and balance quality. Micro 100 TH series tool holders are heat-treated and powdered coated with black oxide to increase the strength and longevity of the tool holding system. The steel bore Head holder enables tight tool engagement and offers holder orientation flexibility by 2 alignment flats on the shank. It helps in providing high-speed clamping force as well as reduced vibrations while machining. Micro 100 TH series steel boring head holder has shank length of 2-3/4 inches. The different variants are available in shank outer diameter of 1/2 inch, 5/8 inch and 3/4 inch in combination with shank inner diameter of 1/8 inch, 3/16 inch, 1/4 inch, 5/16 inch and 3/8 inch. Micro 100 is a market leader and internationally acclaimed tool manufacturer for the last 45 years or more. The company is completely based in the USA and manufactures precision tools for almost all industrial applications.
