Feedmax Deep-Hole Drill

March 01, 2011

Seco Tools has announced the availability of its new Feedmax SD230A solid carbide 30xD drill, which was designed for applications often found in the automotive, oil and gas, mold and die, medical and general engineering industries. Compared to HSS or ordinary solid carbide drills, the Feedmax SD230A offers substantial improvements in terms of hole quality, productivity and length and consistency of tool life.

The Feedmax SD230A is offered in diameters ranging from 4mm to 10mm as standard, with 3mm available as semi-standard. A 4-facet point geometry provides excellent centering capability, with primary and secondary relief angles and a point angle of 136 degrees. The tool also features a low friction, TiAIN + TiN coating for long, predictable tool life. Four land margins provide stability and maximize hole quality.

For the best setup stabilization, Feedmax SD230A drills should be used in conjunction with hydraulic chucks or Shrinkfit toolholders.

    centering

    1. Process of locating the center of a workpiece to be mounted on centers. 2. Process of mounting the workpiece concentric to the machine spindle. See centers.

  • high-speed steels ( HSS)

    high-speed steels ( HSS)

    Available in two major types: tungsten high-speed steels (designated by letter T having tungsten as the principal alloying element) and molybdenum high-speed steels (designated by letter M having molybdenum as the principal alloying element). The type T high-speed steels containing cobalt have higher wear resistance and greater red (hot) hardness, withstanding cutting temperature up to 1,100º F (590º C). The type T steels are used to fabricate metalcutting tools (milling cutters, drills, reamers and taps), woodworking tools, various types of punches and dies, ball and roller bearings. The type M steels are used for cutting tools and various types of dies.

  • land

    land

    Part of the tool body that remains after the flutes are cut.

  • point angle

    point angle

    Included angle at the point of a twist drill or similar tool; for general-purpose tools, the point angle is typically 118°.

  • relief

    relief

    Space provided behind the cutting edges to prevent rubbing. Sometimes called primary relief. Secondary relief provides additional space behind primary relief. Relief on end teeth is axial relief; relief on side teeth is peripheral relief.

  • titanium nitride ( TiN)

    titanium nitride ( TiN)

    Added to titanium-carbide tooling to permit machining of hard metals at high speeds. Also used as a tool coating. See coated tools.
