Kennametal 3100405 Milling Chuck 3.54 in Projection

Product Description

The KENNAMETAL 3100405 is a milling chuck designed to securely hold cutting tools in milling applications. It features a 3.54-inch projection, which determines the distance from the spindle face to the tool tip and directly affects reach and rigidity in the cut. Milling chucks of this type transmit high torque to end mills and similar rotary tools while minimizing runout. This chuck is installed by machinists and tooling technicians on CNC machining centers and conventional milling machines where consistent tool holding performance is required.

This milling chuck is suited for use in metalworking environments, including job shops and production machining facilities. The 3.54-inch projection makes it appropriate for applications requiring moderate reach, such as cavity milling, profiling, and general-purpose end milling operations. It is compatible with milling spindle interfaces matched to KENNAMETAL tooling standards and is typically used where rigid, high-torque tool holding is a priority over quick-change convenience.

Key Features

• 3.54-inch projection for moderate reach in milling operations
• High-torque tool holding suitable for end mills and similar rotary cutting tools
• Designed for use on CNC machining centers and conventional milling machines
• Precision construction minimizes runout for consistent cutting performance

Compatibility

Designed as an OEM-style milling chuck replacement for milling spindle interfaces compatible with KENNAMETAL tooling systems. Verify spindle taper and bore size specifications before installation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before mounting or removing the chuck. Use the appropriate torque wrench and chuck key specified for the spindle interface - never exceed the recommended clamping torque for the tool bore size. Confirm tool runout with a dial indicator after mounting before beginning any cutting operation.
