Curious about Dynamic Milling? DAPRA’s American-made Helical Roughing End Mills are a great option for modern applications. Watch a 3/4" dia. end mill create a 0.850" deep pocket and outside contour in a 4" wide x 6.25" long 1018 steel block, with a total cycle time of just 4 min. 17 sec.

  • 0.25" wall thickness; 0.625" max. radial depth
  • Pocket and outside contour: 0.060" WOC, 6100 RPM, 185 IPM, 0.850" DOC

  • inches per minute ( ipm)

    inches per minute ( ipm)

    Value that refers to how far the workpiece or cutter advances linearly in 1 minute, defined as: ipm = ipt 5 number of effective teeth 5 rpm. Also known as the table feed or machine feed.

  • milling machine ( mill)

    milling machine ( mill)

    Runs endmills and arbor-mounted milling cutters. Features include a head with a spindle that drives the cutters; a column, knee and table that provide motion in the three Cartesian axes; and a base that supports the components and houses the cutting-fluid pump and reservoir. The work is mounted on the table and fed into the rotating cutter or endmill to accomplish the milling steps; vertical milling machines also feed endmills into the work by means of a spindle-mounted quill. Models range from small manual machines to big bed-type and duplex mills. All take one of three basic forms: vertical, horizontal or convertible horizontal/vertical. Vertical machines may be knee-type (the table is mounted on a knee that can be elevated) or bed-type (the table is securely supported and only moves horizontally). In general, horizontal machines are bigger and more powerful, while vertical machines are lighter but more versatile and easier to set up and operate.
