Sandvik Coromant 5722946 ER16 Collet Chuck Straight Shank

Product Description

The SANDVIK COROMANT 5722946 is an ER16 collet chuck with a straight shank and integrated through-coolant capability. It accepts ER16 series collets and is designed for use in CNC machining centers, lathes, and milling machines where precise tool holding and coolant delivery to the cutting zone are required. The shank diameter is 3/4 inch with a shank length of 5.59 inches and an overall length of 7.146 inches. The actuator type is wrench-driven. This tool holder is installed by machinists and CNC tooling technicians in production and job-shop environments.

This collet chuck is suited for light to medium milling, drilling, and reaming operations where the ER16 collet system is the specified standard. The through-coolant feature makes it appropriate for deep-hole drilling and high-speed operations where flood coolant alone is insufficient to clear chips or cool the cutting edge. Typical applications include vertical machining centers and CNC turning centers equipped with a 3/4-inch straight-shank tool station.

Key Features

• ER16 collet system for broad collet compatibility within the ER16 series
• Through-coolant design delivers coolant directly to the cutting zone
• 3/4 inch straight shank diameter for standard tooling stations
• Overall length of 7.146 inches suits extended-reach applications
• Wrench actuator type for secure, repeatable collet clamping
• Nose diameter of 0.8661 inches (22.00 mm) for clearance in confined workpiece geometries

Compatibility

Designed for use with ER16 series collets in CNC machining centers and turning centers equipped with a 3/4-inch straight-shank tool holding station. Specific machine compatibility depends on spindle configuration and tooling block specifications.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle and tool station are fully powered down and the spindle is locked before seating or removing the chuck. Use the appropriate ER wrench and collet nut torque procedure per the machine tool manufacturer guidelines. Inspect the collet, nut, and chuck bore for chips or damage before each use.
