Coolant-Through Thread Mills

March 23, 2016

Allied Machine & Engineering Corp. offers a complete range of coolant-through thread mills that are ideal for blind-hole applications. Allied’s coolant-through threadmills significantly improve chip evacuation when threading blind-holes, according to the company. They reduce tool deflection and provide straighter and more precise thread forms. End users will also achieve longer tool life and experience less tool breakage due to chip build up.

Offered in both inch-shank and metric-shank options, inventory is available for all carried items. Fast delivery times are guaranteed, with same-day shipping on inventoried items. There are more than 100 different items available, including a variety of threadforms, diameters and lengths, with new coolant through thread mill options being added regularly.

Allied’s coolant-through threadmills, ideal for numerous applications in the mold and die, oil and gas, aerospace, and automotive industries, are a versatile solution for producing screw threads. They are perfect for materials that generate heat, especially high-temperature alloys, high-strength alloys and stainless steel used in aerospace and oil and gas applications. Unlike taps, threadmills can produce a variety of thread diameters as well as right- or left-hand threads.

The new Allied design features a thick core geometry, which maximizes the coolant hole size through the center. The increased core diameter strengthens the tool and allows more coolant flow-through, resulting in faster flushing and better cutting edge cooling.

Allied supports threadmill customers with a large team of field sales engineers all over the globe. This technical support team can help set up the tool, ensure it is running correctly, and troubleshoot any problems that may arise. Also available free of charge is an online thread mill programming tool, available 24/7, which prepares the G-code program to run the thread mill based on the specific application parameters.

Related Glossary Terms

  • alloys


    Substances having metallic properties and being composed of two or more chemical elements of which at least one is a metal.

  • blind-hole


    Hole or cavity cut in a solid shape that does not connect with other holes or exit through the workpiece.

  • 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.

  • 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.

  • threading


    Process of both external (e.g., thread milling) and internal (e.g., tapping, thread milling) cutting, turning and rolling of threads into particular material. Standardized specifications are available to determine the desired results of the threading process. Numerous thread-series designations are written for specific applications. Threading often is performed on a lathe. Specifications such as thread height are critical in determining the strength of the threads. The material used is taken into consideration in determining the expected results of any particular application for that threaded piece. In external threading, a calculated depth is required as well as a particular angle to the cut. To perform internal threading, the exact diameter to bore the hole is critical before threading. The threads are distinguished from one another by the amount of tolerance and/or allowance that is specified. See turning.
