Kennametal 2079282 Hydraulic Chuck CAT40 18mm

Product Description

The KENNAMETAL 2079282 is a hydraulic tool chuck with a CAT40 taper shank, designed for precision tool holding in CNC machining centers. It accepts an 18 mm bore diameter and delivers a projection of 102 mm, a nose diameter of 39.6 mm, and a clamping depth of 41 mm. Rated to 15,000 RPM and equipped with through-coolant capability, this chuck is built for high-speed, high-accuracy metal cutting applications. Machinists and tooling technicians install this chuck to achieve consistent radial runout and secure tool grip during milling, drilling, or boring operations.

This hydraulic chuck is suited for use in horizontal and vertical CNC machining centers that accept CAT40 spindle interfaces. The through-coolant feature supports directed coolant delivery to the cutting edge, which is critical in deep-pocket milling, long-reach drilling, and heat-sensitive materials. With an overall length of 170.25 mm and a clamping depth of 41 mm, this chuck accommodates a range of cylindrical shank tooling in production and job-shop environments. It is installed by machine tool operators and CNC tooling technicians in both shop-floor and precision manufacturing settings.

Key Features

• CAT40 taper shank for direct spindle mounting on standard CAT40 machining centers
• 18 mm bore diameter with 41 mm clamping depth for secure cylindrical shank grip
• Hydraulic clamping mechanism provides high gripping force and low runout
• Rated to 15,000 RPM for high-speed machining applications
• Through-coolant capable for directed coolant flow to the cutting zone
• 102 mm projection and 39.6 mm nose diameter for accessibility in confined workspaces

Compatibility

Designed as an OEM-style hydraulic tool chuck for CNC machining centers equipped with a CAT40 spindle taper interface and compatible with cylindrical shank tooling at 18 mm bore diameter.

Installation Notes

Installation should be performed by a qualified CNC tooling technician or machinist familiar with CAT40 tooling systems. Before mounting or removing the chuck, de-energize the machine and follow all lockout/tagout procedures per OSHA and facility safety standards. Use the appropriate CAT40 pull stud and torque the retention knob to the machining center manufacturer's specification — do not estimate or exceed the spindle's draw-bar force rating. Inspect the hydraulic chuck for contamination or damage to the bore before each use, as debris can affect clamping force and runout.
