Important Update Regarding Sherline Products
October 20, 2026
We would like to share an encouraging development regarding the future of Sherline Products.
We are currently in discussions with an American manufacturer regarding the potential purchase of Sherline’s intellectual property and remaining inventory. The goal of this proposed acquisition is to preserve and revitalize the Sherline brand while providing continued availability of replacement parts, accessories, and machines for our valued customers.
As these discussions progress, we have agreed to temporarily suspend accepting new orders, effective October 19, 2026. This will allow us to preserve our remaining inventory while negotiations are underway.
Although no final agreement has been reached, we are hopeful that this opportunity will provide a positive path forward for the Sherline name and the customers who have trusted our products for more than five decades.
We sincerely appreciate your patience, understanding, and continued loyalty during this transition. We will share additional information as soon as it becomes available.
Our greatest hope is that the Sherline legacy of quality, precision, and American craftsmanship will continue for generations to come.

    Indexing Attachment

    Machining operations often require cutting features in a radial pattern rather than in a straight line. Common examples include gear teeth, splines, and flats on nuts. The Sherline Indexing Attachment provides an economical and highly accurate way to rotate and position a workpiece for machining these types of features.

    Features & Benefits
    • Ideal for machining radial patterns such as flats, splines, and gear teeth
    • Built-in detent mechanism indexes the spindle in 5° increments
    • Laser-engraved collar provides 1° reference markings
    • Rack gear system allows indexing to virtually any position using simple calculations
    • Compatible with many Sherline workholding accessories
    Included Components
    • Indexing head and tailstock mounted on a 12" dovetailed bed
    • Rack gear for measuring radial movement
    • Gear tooth cutter holder
    • High-speed steel tool blank
    Spindle Compatibility

    The indexing head uses a spindle with a #1 Morse taper and 3/4"-16 male thread, identical to Sherline lathe and mill spindles. This allows the use of common Sherline accessories, including:

    • Faceplate
    • 3-jaw and 4-jaw chucks
    • Drill chuck
    • Centers
    Precision Indexing Capability

    For positions beyond the standard 5° detents, the rack gear converts spindle rotation into measurable linear travel. This movement can be measured with the depth rod of a Vernier caliper, allowing extremely accurate indexing to an infinite number of positions.

    Mounting & Use

    The indexing attachment can be mounted directly to the table of a Sherline milling machine. The indexing head may also be used independently in a horizontal position similar to a rotary table.

    Note: Use on a Sherline lathe with the vertical milling column is not recommended. However, it may be possible with shims installed to raise the unit high enough to clear the crosslide handwheel.
