Value Collection SC88953930 ER32 Collet Chuck Straight Shank

Product Description

The VALUE COLLECTION SC88953930 is an ER32 collet chuck with a straight shank, designed for use in CNC machining centers, manual mills, and drill presses where precise tool holding is required. The chuck features a 1-inch projection and accepts the full range of ER32 collets, delivering a total indicator runout (TIR) of 0.0004 inches for reliable concentricity in production and job-shop environments. With a 1-1/4-inch straight shank diameter and an overall length of 6.2 inches, this chuck suits a wide range of spindle configurations used by machinists and toolroom professionals.

This ER32 collet chuck is suited for light to medium-duty machining operations in both production and prototype environments. The straight shank design allows direct installation into spindles and tool holders with a matching 1-1/4-inch bore. It is commonly used in milling, drilling, reaming, and tapping applications where consistent tool runout is critical to part quality. No through-coolant capability is provided, making it best suited for dry or flood-coolant setups where internal coolant delivery is not required.

Key Features

• ER32 collet system compatibility for broad tooling range
• 0.0004-inch TIR for high concentricity and repeatable tool positioning
• 1-1/4-inch straight shank for direct spindle installation
• 1-inch projection keeps tooling close to the spindle face
• Overall length of 6.2 inches suits a variety of machine clearances
• No through-coolant — compatible with external flood or dry cutting setups

Compatibility

Designed as a straight-shank ER32 collet chuck for use with any machine spindle or tool holder accepting a 1-1/4-inch straight shank bore and standard ER32 collets.

Installation Notes

Installation should be performed by a qualified machinist with the spindle or machine fully powered down and locked out per applicable safety procedures. Ensure the shank bore and shank surfaces are clean and free of burrs before seating the chuck. Verify runout with a dial indicator after installation to confirm TIR is within acceptable limits for the application. Do not exceed the spindle speed ratings specified by the machine manufacturer for the shank diameter in use.
