The Sherline 3/4-16 x 1/2" OD Straight Chuck Arbor is an essential tool for those utilizing large mills or lathes with 5C, ER, or other sizable collets. This adapter facilitates the swift transition to a smaller chuck without the need to alter the spindle or switch machines. It features a 1/2" shank on one end and a 3/4-16 thread on the other, compatible with any Sherline 2.5" or 3.1" chuck. This design allows for the quick installation of a Sherline 3- or 4-jaw chuck by simply inserting the adapter's shank into a 1/2" collet, enabling the secure holding of parts that are challenging to manage with a collet alone.
The adapter is crafted from unhardened steel and is finished with a black oxide coating to resist rust, ensuring durability and longevity. The total indicated runout (T.I.R.) of the adapter is precisely specified to be 0.0005" (0.013mm) or less, ensuring high precision and reliability in operations. This makes it an invaluable addition to any machining setup, providing both versatility and efficiency in handling various components.
