Value Collection 235-7051 Lever Collet Closer 5C 4 Inch

Product Description

The VALUE COLLECTION 235-7051 is a lever collet closer designed for use with 5C collet series tooling in machining and workholding applications. It features a 4-inch centerline height, making it compatible with standard collet block chuck setups used on milling machines, rotary tables, and similar equipment. The lever-style mechanism allows the operator to engage and disengage the collet quickly without additional tooling, supporting efficient part changeover. Weighing 1.05 pounds, this closer is a lightweight yet functional accessory for shops running 5C collet systems. Installation is handled by machinists and toolroom technicians familiar with collet block workholding.

This lever collet closer is intended for use with collet block chucks that accept 5C series collets. It is suited to both production and job shop environments where collet block workholding is standard practice. Typical applications include horizontal and vertical milling setups, indexing operations, and secondary machining where collet blocks are used to hold round or hex stock securely. The 4-inch centerline height positions the workpiece at the correct reference plane for collet block chuck configurations.

Key Features

• Lever-style closure mechanism for fast collet engagement and release without separate tooling
• 4-inch centerline height matches standard collet block chuck reference dimensions
• Compatible with 5C collet series, one of the most widely used collet standards in production machining
• Lightweight at 1.05 pounds, reducing operator fatigue during frequent part changes
• Single-piece package quantity suitable for individual workstation use

Compatibility

Designed for use with 5C series collet block chucks. Verify collet block chuck manufacturer specifications for centerline height and closer interface requirements before installation.

Installation Notes

Installation and adjustment of collet closers should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle or rotary table is fully de-energized and any stored energy is released before working on the collet block assembly. Confirm that the closer is properly seated and the lever engages the collet draw mechanism fully before returning the workpiece to service. Do not overtighten or force the lever beyond its designed travel.
