Industries Benefiting From Rotary Broaching
Polygon Solutions’ innovative and award winning Rotary Broaching Tools are used by a variety of precision machining companies. Because our rotary broach holder will work on virtually any lathe, mill, or turning machine, a large number of applications can be improved by eliminating secondary operations and creating broached forms. The Medical, Aerospace, Automotive, Plumbing and Fastener industries benefit significantly from the use of rotary broaching tools.
Rotary broaching has numerous uses in the Medical Industry including bone screw and implant applications with hexagon, Torx® style, six-lobe or hexalobular drive features. Due to the demanding nature of the medical field for reliability in surgical procedures, machining standards for surgical equipment tend to be very precise compared to other similar size and material metal parts.
Various grades of stainless steel, titanium and other exotic and experimental materials are used to make these bone screws and implant fasteners. Rotary Broaching makes an easy job of putting a shape in the head of a bone screw made with such materials. Our tool holder is designed for use in all modern turning machines.

Rotary broaching uses the full force of standard turning machines to create polygon shaped holes. These holes are manufactured in precision machined metal products. The aerospace industry has unique needs for customized, lightweight, precise and high-strength fastener products. This need makes this tool an excellent addition to any aerospace machining facility. Rotary broaches are available with standard hexagon, square and custom made shapes.
Typical screws, bolts and other fasteners are made in mass production processes. Stamping or cold heading the form into the end of the part makes financial sense. However, in the case of smaller production needs, or prototype products, cold heading resources are not available. Since our tool holder is practical for use on any CNC, lathe or milling machine, it is the ideal tool for such work. Read more on Rotary Broaching in the Aerospace Industry
The main advantage of a rotary broaching operation is that processes can be completed on the machine where the part is first turned or milled. This eliminates subsequent operations and results in savings of time and money. Automotive suppliers intent on reducing costs due to fierce competition may reverse engineer some part features to take advantage of this machining technique.
Besides typical hexagon, square and Torx-style blind holes, rotary broaching is also popular for creating serrations and splines (including involute splines). These gear shapes are broached into bolts, drivers, linkage, shafts and other parts where cold heading, stamping or other machining methods are not possible, practical or cost effective. This process is a very fast and accurate method of creating small polygon, star and gear shaped forms. Read more on Rotary Broaching in the Automotive Industry
The plumbing industry’s use of brass parts for hydraulic, pneumatic, and liquid transfer makes rotary broaching a popular option for machining. Hexagon and square holes can easily be created in brass with standard rotary broaching tools. High volume machines, such as CNC and screw machines, can economically use these tools to create thousands of parts per broach. Read more on Rotary Broaching in the Plumbing Industry
Most fasteners are screws, nails, staples and other retaining devices used to hold mechanical pieces or materials together. Most are mass produced in very high volume processes requiring little customizing or precision. The need for precision fasteners does exist however, and these are the parts that can benefit from rotary broaching tools.
A wide variety of industries require precision made fasteners. The medical industry uses bone screws and other fixation devices that are often held to very high standards for good reason. No one wants to hear that a screw stripped while tightening it into the femur, especially the patient. Hardware manufacturers make specialty handles and hinges requiring screws of various lengths and visual appearance. Aerospace fasteners may be fabricated from exotic lightweight and high strength materials. Brass plumbing screws may be customized for strength, length, flow and visual appearance.
