Kennametal 2541970 Indexable Square-shoulder End Mill CV40

Product Description

The KENNAMETAL 2541970 is an indexable square-shoulder end mill designed for precise 90-degree shoulder milling operations in metalworking and machining applications. Built with a CV40 taper shank, it accepts three indexable inserts and delivers a maximum cutting diameter of 1.25 inches with a maximum depth of cut of 3 inches. The head length measures 4.875 inches. Through-coolant capability is integrated into the design, allowing direct delivery of coolant to the cutting zone to manage heat and extend insert life. This tool is installed and operated by machinists and CNC tooling technicians working with milling machines equipped with CV40 spindle interfaces.

This end mill is suited for square-shoulder and face milling operations on ferrous and non-ferrous materials in production and job-shop environments. The CV40 taper shank interface is compatible with standard CV40 spindle toolholders on vertical and horizontal machining centers. With a maximum rated speed of 32,300 RPM and support for through-coolant, it is well-matched to high-speed finishing and semi-finishing passes where chip evacuation and thermal management are priorities.

Key Features

• 1.25-inch cutting diameter for square-shoulder milling applications
• CV40 taper shank for direct spindle mounting on compatible machining centers
• Accepts 3 indexable inserts for cost-effective edge replacement without full tool changeover
• Through-coolant design directs fluid to the cutting zone for improved chip evacuation and heat control
• Maximum depth of cut of 3 inches supports deep shoulder passes in a single setup
• Maximum spindle speed rated at 32,300 RPM for high-speed machining capability

Compatibility

Designed for use with CV40 taper spindle interfaces on vertical and horizontal CNC machining centers. Specific machine model compatibility depends on spindle interface and drawbar configuration — verify CV40 toolholder fitment before installation.

Installation Notes

Installation and tool setup should be performed by a qualified machinist or CNC tooling technician. Always power down and lock out the machining center spindle before mounting or removing the tool. Ensure the CV40 taper shank and spindle bore are clean and free of debris before seating the tool. Confirm insert seating and clamping torque per insert manufacturer guidelines before initiating a cut.
