Kennametal 3795030 ER32 Collet Chuck KM50TS Through Coolant

Product Description

The KENNAMETAL 3795030 is an ER32 collet chuck designed for precision workholding in CNC machining centers and turning centers equipped with a KM50TS modular connection interface. It accepts the full ER32 collet series and handles tool shanks from 1 mm to 20 mm (0.0394 to 0.7874 inches) in diameter. The chuck projects 2.3622 inches (60 mm) from the spindle face and features through-spindle coolant delivery, directing coolant directly to the cutting edge for improved chip evacuation and tool life. Actuation is accomplished with a standard collet wrench. This chuck is installed by CNC setup technicians and machining professionals in production and job-shop environments.

The 3795030 is suited for milling, drilling, reaming, and tapping operations where a rigid, accurate ER-style collet connection is required. The KM50TS modular shank allows fast, repeatable tool changes without removing the chuck body from the spindle, making it a practical choice for high-mix production cells and tool-preset workflows. Its through-coolant path supports flood and high-pressure coolant systems, reducing heat buildup during deep-cavity or high-speed operations.

• Wrench-actuated collet nut with 50 mm (1.9685-inch) diameter
• Compact, balanced design suited for moderate to high spindle speeds

Compatibility

Designed for use with spindles equipped with a KM50TS modular connection interface and compatible with the ER32 collet series across the full 1 to 20 mm capacity range.

Installation Notes

Installation and removal should be performed by a qualified CNC machinist or toolroom technician. Power down and lock out the spindle drive before handling the chuck or collet. Ensure the KM50TS mating surfaces are clean and free of chips or coolant residue before seating the chuck to maintain runout accuracy. Torque the collet nut using the correct ER32 wrench; do not use pipe wrenches or improvised tools that can damage the nut or collet taper.
