Kennametal 3331467 Square End Mill 4 Flute Solid Carbide Altin

Product Description

The KENNAMETAL 3331467 is a solid carbide square end mill designed for high-performance milling in demanding shop environments. Measuring 0.5 inches in cutting diameter with a 1.25-inch length of cut and a 3-inch overall length, this tool is built for precision metal removal in ferrous and hardened materials. The AlTiN coating provides heat resistance and extended tool life at elevated cutting speeds. The KC643M micrograin carbide grade delivers edge strength and wear resistance. With four spiral flutes and a variable index design, it reduces chatter and produces consistent surface finishes. This end mill is typically installed and run by machinists and CNC operators in production and job shop environments.

The 3331467 is a single-end, centercutting end mill suited for peripheral and plunge milling operations. Its right-hand cut and right-hand flute configuration is standard for vertical machining centers and CNC milling machines. The HPHVT series designation identifies it as a high-performance, high-velocity tooling line, commonly applied to aggressive roughing and finishing passes in steel, stainless, cast iron, and similar materials. The 0.5-inch shank diameter fits standard ER and side-lock toolholders common in production machining setups.

Key Features

• Solid carbide construction with KC643M micrograin grade for edge retention in hard materials
• AlTiN coating for heat resistance and extended tool life at high cutting speeds
• Variable index flute geometry reduces vibration and chatter during aggressive cuts
• Centercutting design allows direct plunge entry without pre-drilling
• Right-hand cut and right-hand spiral flutes for standard CNC milling spindle compatibility
• HPHVT series engineered for high-velocity, high-performance milling applications

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill for CNC vertical machining centers and manual mills accepting a 0.5-inch shank diameter. No specific machine model compatibility was stated by the manufacturer for this SKU.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank fully into a clean, properly sized toolholder and torque the retention mechanism to the toolholder manufacturer's specification. Inspect the cutting edges and coating for chips or damage before mounting. Never exceed the spindle RPM and feed rate parameters established during setup for the specific workpiece material and depth of cut.
