Patriot High Performance (HP) Drill

March 11, 2021
Available in 3XD, 5XD, and 8XD with MQL Shank Standard on All Sizes

ARCH® Cutting Tools, with its 2021 newly expanded Patriot High Performance™ (HP) Drill offering, has dramatically improved the Patriot HP portfolio, which, at its introduction in 2018, was a breakthrough in cutting tool innovation. The new Patriot HP expansion offers more and more versatile, high-performance tools from solid carbide to indexable milling options, in addition to indexable and solid drilling. That’s how you make the leading high-performance drill better – and with 100 percent American-made quality and reliability, increased productivity and operational efficiency – and a potential gain of 20 percent or more in process improvement, the expanded Patriot HP portfolio should be in your cutting tool “toolbox.” 

The strength of 80 years cutting tool engineering know how, and the driven strength in custom drilling solutions, has allowed ARCH Cutting Tools to design one of the most accomplished drill offerings in the industry to date. The precision through coolant and low friction coating provides the highest level of chip evacuation. Complemented with low thrust force design with a 140º point angle suited for multi-application drilling. Increasing tool life will provide greater process security and better machine utilization. Available in 3XD, 5XD, and 8XD with MQL shank standard on all sizes. This drill is for close hole tolerances with a geometry suitable for all workpiece materials. 

Incorporating a wide range of drill lengths and diameters, ARCH Cutting Tools Patriot High Performance portfolio of solid carbide drills excels across the broad spectrum of all ISO class workpiece materials, from general steels, cast irons, HSRA, and many more. With diameters as small as 0.8 mm (0.0314 inches) and up to 20.0mm (0.7874 inches), single or double margin offering based on cutting diameter. Our range covers a comprehensive application base, providing a universal geometry suitable for most applications across all industry segments that focus on hole quality. These include die and mold, automotive, medical, and aerospace.​

Related Glossary Terms

  • cast irons

    cast irons

    Cast ferrous alloys containing carbon in excess of solubility in austenite that exists in the alloy at the eutectic temperature. Cast irons include gray cast iron, white cast iron, malleable cast iron and ductile, or nodular, cast iron. The word “cast” is often left out.

  • coolant


    Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.

  • gang cutting ( milling)

    gang cutting ( milling)

    Machining with several cutters mounted on a single arbor, generally for simultaneous cutting.

  • milling


    Machining operation in which metal or other material is removed by applying power to a rotating cutter. In vertical milling, the cutting tool is mounted vertically on the spindle. In horizontal milling, the cutting tool is mounted horizontally, either directly on the spindle or on an arbor. Horizontal milling is further broken down into conventional milling, where the cutter rotates opposite the direction of feed, or “up” into the workpiece; and climb milling, where the cutter rotates in the direction of feed, or “down” into the workpiece. Milling operations include plane or surface milling, endmilling, facemilling, angle milling, form milling and profiling.

  • 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°.

  • shank


    Main body of a tool; the portion of a drill or similar end-held tool that fits into a collet, chuck or similar mounting device.
