Cartridges for Indexable-Insert Drills and Boring Heads

June 01, 2016

The new rectangular cartridges from E-Z Burr Tool are a custom-made solution for indexable drills and adjustable precision boring heads. Now you can accomplish two operations in one convenient pass. The company simply mills a trench in an indexable drill or boring head and installs a custom-designed deburring cartridge that slides right into the trench. The cartridge has the same patented E-Z Burr performance features that are consistent with its highest-quality carbide series tools.

The company can work with end users to have the proper modification made to an existing drill or boring head to allow these cartridges to drop right in.

E-Z Burr currently supplies these cartridges to several large customers, including a large excavation machinery company, a major truck wheel maker and a steel mill.

Related Glossary Terms

  • boring


    Enlarging a hole that already has been drilled or cored. Generally, it is an operation of truing the previously drilled hole with a single-point, lathe-type tool. Boring is essentially internal turning, in that usually a single-point cutting tool forms the internal shape. Some tools are available with two cutting edges to balance cutting forces.

  • boring head

    boring head

    Single- or multiple-point precision tool used to bring an existing hole within dimensional tolerance. The head attaches to a standard toolholder and a mechanism permits fine adjustments to be made to the head within a diameter range.

  • burr


    Stringy portions of material formed on workpiece edges during machining. Often sharp. Can be removed with hand files, abrasive wheels or belts, wire wheels, abrasive-fiber brushes, waterjet equipment or other methods.

  • 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.
