Kennametal 6136881 End Mill Holder Straight Shank 3/4 in

Product Description

The KENNAMETAL 6136881 is a straight-shank end mill holder engineered for precision CNC machining applications. It features a 3/4-inch bore diameter and a 7.5-inch projection length, making it well suited for operations that require extended reach without sacrificing rigidity. The modular connection size is DL20. A through-coolant design channels cutting fluid directly to the tool tip, improving chip evacuation and heat management during milling operations. Machinists and CNC setup technicians working in production environments install this holder as part of a modular tooling system.

This end mill holder is intended for use in CNC machining centers equipped with a compatible DL20 modular interface. The 7.5-inch overall length and 7.5-inch projection make it appropriate for deep-pocket milling, cavity work, or any application where standard-length holders cannot reach the workpiece. The through-coolant feature is particularly beneficial in high-feed or difficult-to-machine materials where flood coolant alone is insufficient.

Key Features

• 3/4-inch hole diameter for secure end mill retention
• 7.5-inch projection and overall length for extended reach applications
• DL20 modular connection size for system compatibility
• Through-coolant capability for improved chip evacuation and tool life
• 0.73-inch nose diameter for clearance in tight workpiece geometries

Compatibility

Designed for use with DL20 modular tooling interfaces on compatible CNC machining centers. Verify spindle interface and modular connection specifications before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the tool carousel is safe before inserting or removing holders. Use the appropriate torque wrench and manufacturer-specified clamping procedures for the modular connection. Confirm through-coolant passages are clear and the coolant supply line is properly connected before resuming cutting operations.
