    Expanding Ring Mandrel

    Sherline Products, in collaboration with Bryan D. Drummond (gem cutter and goldsmith), designed this Expanding Ring Mandrel specifically for making and modifying rings on the Sherline lathe.

    The mandrel is manufactured from 12L14 steel and features a black oxide finish for rust prevention.

    It is designed for use with stepped ring collets manufactured by Ring Tech (Faceting Collets Stepped). These Ring Tech collets are known for their excellent quality and superior design, and, like our machines, are made in the USA.

    If you are using a brand of collet that is shorter than the Ring Tech collets, the mandrel includes a spacer washer that fits against the shoulder of the mandrel. This allows shorter collets to be properly positioned at the front of the mandrel.

    3C Step Collet

    The 3C Step Collet features a 2″ diameter and 1″ depth, making it an excellent addition for machinists using the Sherline 3C headstock. It can be easily machined to size and is specifically designed to hold larger workpieces.

    A 1/4″ (6.35 mm) dowel pin is included to provide a gripping surface during the boring process. This helps minimize runout and ensures greater accuracy in the finished bore. Once machined to the desired diameter and depth, the collet effectively becomes a custom chuck—ideal for parts too large for standard 3C collets.

    Other head sizes may be available. Please contact Sherline for additional options and pricing.

    NOTE: This step collet is designed to grip material only at the face end, not through the collet. Maximum gripping depth is approximately 3/4″ to 7/8″ (19.05 mm to 22.23 mm).

    Contact us to inquire about other available step collet head sizes.

    55° RH and LH Tool Holders for Inserts w/7° Relief Angle
    These holders are identical to our standard 55° Insert Tool Holders, with one key distinction. While our original 55° holders are designed for DPMT inserts with an 11° relief angle, these updated holders are configured for DCMT inserts, which feature a 7° relief angle. Over time, insert availability and design options evolve. The DPMT insert, once standard in our 55° holders, has become increasingly scarce and offers fewer chip breaker variations. In contrast, the DCMT insert is widely available and comes in a broad range of styles, making it a more versatile and accessible option. Note: Many customers machining brass found excellent results with our uncoated 11° DPMT insert featuring a straight-groove chip breaker. Unfortunately, this insert is no longer available. That’s why we introduced these updated holders to accommodate 7° DCMT inserts. For those working with brass, insert P/N 7613 is an ideal replacement. It cuts cleanly and delivers a high-quality surface finish. Coated inserts with various chip breaker designs are still available for both DPMT and DCMT styles. Holders & Inserts sold separately
