Value Collection 235-7065 Collet Block Chuck ER40

Product Description

The VALUE COLLECTION 235-7065 is a manual, non-indexing collet block chuck designed for secure workpiece holding in milling, grinding, and inspection setups. Built from steel, this horizontal-orientation fixture accepts ER40-series collets with a minimum capacity of 0.125 inches and a maximum capacity of 1-1/64 inches, covering a broad range of round stock and tool shank sizes. At 2 pounds, the chuck is rigid enough for production use while remaining manageable for setup changes. Machinists and toolroom technicians use this type of fixture when a fixed, non-rotating hold is required on a mill table, surface grinder, or CMM.

This collet block chuck is suited for horizontal workholding applications in job shop and production machining environments. The manual activation method keeps the setup straightforward — no hydraulic or pneumatic lines required. It is appropriate for use on vertical mills, horizontal mills, and surface grinders where the part must be held square and stationary. The ER40 collet series compatibility gives technicians access to a wide selection of readily available collets for different bore sizes within the stated capacity range.

Key Features

Compatibility

Designed for use with ER40-series collets. Confirm collet series and shank diameter before installation to ensure proper fit within the stated capacity range of 0.125 inches to 1-1/64 inches.

Installation Notes

Installation is typically performed by a machinist or toolroom technician. Ensure the machine table or fixture plate is clean and free of chips before mounting the block. Torque the collet nut using the appropriate ER40 spanner wrench — do not use pipe wrenches or improvised tools on the collet nut. Verify workpiece runout and seating before beginning any machining operation.
