Sherline 3C Collet Headstock

Description

• Sherline 3C Collet Headstock
• Accommodates 1/2″ diameter stock
• Interchangeable with standard headstock
• Nickel-plated for rust prevention
• Precision ground head key included
• Supports 3C collets from top brands

The Sherline 3C Collet Headstock is designed to accommodate larger diameter stock, allowing materials up to 1/2 inch in diameter to pass through the headstock. This headstock is interchangeable with the standard Sherline headstock, maintaining the same centerline height and mounting system, which facilitates easy switching between headstocks. The spindle is electroless nickel plated, enhancing rust prevention and increasing surface hardness for improved durability. The headstock comes equipped with a spindle pulley and a precision ground head key. For those wishing to use a chuck with the 3C headstock, a 3C to -16 chuck arbor is available for purchase, compatible with all Sherline 3- and 4-jaw chucks featuring a -16 thread. While Sherline does not manufacture 3C collets, customers are encouraged to select from reputable manufacturers such as Hardinge, known for their quality collets in various sizes.
