Value Collection SC81197253 ER11 Collet Chuck Straight Shank

Product Description

The VALUE COLLECTION SC81197253 is an ER11 collet chuck with a straight shank, designed for use in CNC machining centers, milling machines, and drilling applications. This chuck accepts ER11 series collets and delivers a Total Indicator Runout (TIR) of 0.0004 inches, providing the concentricity required for precision toolholding in light to medium-duty cutting operations. With a 1-inch projection and an overall length of 3.5 inches, it fits a range of machine spindle configurations. Machinists and toolroom technicians install this chuck as part of a collet-based workholding or toolholding setup where accuracy and repeatability are critical.

This ER11 collet chuck suits residential shop equipment and commercial machine tool environments alike. It is commonly installed in CNC routers, benchtop mills, and multi-spindle drilling units where the ER11 collet system is the specified standard. The straight shank design allows direct insertion into machine spindles or tool holders with matching bore diameters. Its compact shank diameter of 0.625 inches makes it appropriate for smaller spindle configurations typically found in precision machining and light production work.

Key Features

• ER11 collet system compatibility for broad collet size range within the ER11 series
• 0.0004-inch TIR for high concentricity and precision toolholding
• Straight shank with 0.625-inch diameter for direct spindle or holder insertion
• 1-inch projection keeps tooling close to the spindle face, reducing overhang and vibration
• 3.5-inch overall length suits compact machine configurations
• Lightweight at 0.396 pounds for reduced spindle load

Compatibility

Designed as a standard ER11 collet chuck replacement or addition for machine tools configured with a straight shank spindle bore or matching toolholder accepting a 0.625-inch straight shank.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle completely before inserting or removing the chuck. Use the appropriate ER11 collet nut wrench and spanner to achieve proper collet seating and clamping force. Do not exceed the collet series clamping range, and inspect the collet and chuck bore for debris or damage before each use.
