Value Collection 290-1175 Lathe Chuck Key 10 Inch

Product Description

The VALUE COLLECTION 290-1175 is a lathe chuck key designed to tighten and release three-jaw and four-jaw lathe chucks in machine shop and production turning applications. The key fits chucks with a 10 inch diameter and features a 0.5 inch square drive that engages the chuck's bevel gear socket. The 4 inch body length provides the leverage and clearance needed for controlled tightening without over-torquing the chuck jaws. Weighing 0.75 pounds, the tool is sized for bench lathe and floor-model lathe use. Machinists, toolroom technicians, and maintenance professionals are the primary users of this accessory.

This chuck key is intended for use with 10 inch lathe chucks commonly found on mid-size engine lathes and toolroom lathes in residential shops, vocational training facilities, and light industrial environments. The 0.5 inch square drive fits the standard bevel gear socket found on most chucks of this diameter. This is a manually operated, non-self-ejecting key, so the operator is responsible for removing it from the chuck before engaging the lathe spindle.

Key Features

• Fits 10 inch diameter lathe chucks with a standard bevel gear socket
• 0.5 inch square drive size for positive chuck engagement
• 4 inch body length provides controlled leverage during jaw adjustment
• Non-self-ejecting design — operator must remove key before spindle rotation
• Compact 0.75 pound weight for easy one-handed use at the lathe

Compatibility

Designed as a replacement or spare chuck key for 10 inch diameter lathe chucks that accept a 0.5 inch square drive. Verify the square drive size and chuck diameter against your existing chuck specifications before ordering.

Installation Notes

Always ensure the lathe spindle is fully stopped and the power disconnect is locked out before inserting the chuck key. Engage the square drive fully into the chuck socket before applying torque to avoid rounding the socket. Never leave the chuck key inserted in the chuck when the lathe is powered or unattended — this is a critical safety requirement in any machine shop environment. A licensed machinist or qualified shop technician should perform chuck maintenance and jaw adjustment.
