Kennametal 2658450 Square End Mill 3/4 in 3 Flute Carbide

Product Description

The KENNAMETAL 2658450 is a solid carbide square end mill designed for high-performance milling in demanding machining environments. Built to SFRHEC series standards, it features a 3/4-inch cutting diameter, a 2-1/4-inch length of cut, and a 5-inch overall length with a 3/4-inch shank. The three-flute, fine-pitch geometry with a 37-degree helix and right-hand cut with right-hand flute direction delivers efficient chip evacuation and smooth cutting action. Micrograin carbide construction provides the hardness and wear resistance needed for precision work in ferrous and non-ferrous materials. This is a single-end, centercutting tool, meaning it can plunge directly into a workpiece.

This end mill is suited for slot milling, peripheral milling, and plunge operations on CNC machining centers and manual mills. The uncoated bright finish makes it a reliable choice for applications where coating buildup or heat sensitivity is a concern, or where the part will be re-ground. Typical users include CNC machinists, toolroom operators, and production shops running steel, aluminum, and similar workpiece materials. The centercutting capability adds versatility for cavity work and ramping operations.

Key Features

• Solid micrograin carbide construction for hardness and wear resistance
• 3-flute fine-pitch geometry with 37-degree helix for efficient chip removal
• Centercutting design allows direct plunge entry into workpiece
• Right-hand cut and right-hand flute for standard spindle rotation
• Uncoated bright finish suitable for regrinding and heat-sensitive applications
• Single-end configuration with 3/4-inch shank for secure tool holding

Compatibility

Designed as an OEM-style solid carbide square end mill for use in standard 3/4-inch tool holders, collet chucks, and end mill holders on CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or toolroom professional. Ensure the spindle is fully stopped and the machine is in an off or locked-out state before changing tooling. Seat the shank fully into a properly sized collet or end mill holder and torque the retention hardware to the tool holder manufacturer specification. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates wear on carbide tooling.
