Kennametal 4047737 Square End Mill 5/16 in 4 Flute Carbide

Product Description

The KENNAMETAL 4047737 is a solid carbide square end mill designed for high-performance material removal in ferrous machining applications. Measuring 0.3125 inches in diameter with a 0.5 inch length of cut and 2 inches overall length, this single-end mill runs a 4-flute, spiral-flute geometry at a 38-degree helix angle. The AlTiN coating improves heat resistance and tool life when cutting steel, stainless steel, cast iron, and hardened materials. It belongs to the HPHV series and features a variable index geometry that reduces chatter and improves surface finish at aggressive feed rates. Solid carbide construction from material grade KCPM15 provides the rigidity needed for demanding cuts. Right-hand cut and right-hand flute orientation are standard.

This end mill is suited for milling operations on machining centers and CNC mills handling steel, stainless steel, cast iron, and hardened materials in job shop and production environments. The center-cutting design allows plunge entry, making it practical for pocketing, slotting, and profiling without a pre-drilled entry point. The 5/16 inch shank diameter fits standard ER collet chucks and end mill holders commonly found in vertical and horizontal machining centers. It is a single-piece solid carbide tool — no inserts to index.

Key Features

• Solid carbide construction from KCPM15 grade for high wear resistance
• AlTiN coating for elevated heat resistance in steel and hardened material cutting
• 4-flute spiral geometry with 38-degree helix angle for efficient chip evacuation
• Variable index flute spacing reduces vibration and chatter at high feed rates
• Center-cutting capable — supports direct plunge entry for pocketing operations
• Right-hand cut, right-hand flute; single-end configuration

Compatibility

Rated for primary workpiece materials including steel, stainless steel, cast iron, and hardened materials per material codes P, M, K, and H. Belongs to the KENNAMETAL HPHV series.

Installation Notes

Installation is performed by a machinist or CNC tooling technician. Secure the 5/16 inch shank in a properly sized collet chuck or end mill holder and verify runout before cutting. Power down and lock out the spindle before changing tooling. Follow shop-specific feeds and speeds guidelines for the HPHV series and the specific workpiece material being machined.
