Kennametal 4048737 Square End Mill 3/4 in 5 Flute Carbide

Product Description

The KENNAMETAL 4048737 is a single-end square end mill designed for demanding metal removal in ferrous and hardened materials. Built from solid carbide and coated with AlTiN, it delivers high heat resistance and extended tool life in aggressive cutting applications. The cutter measures 0.75 inches in diameter with a 1.5-inch length of cut and a 4-inch overall length. Five spiral flutes with a variable index geometry reduce harmonic vibration, improve chip evacuation, and produce consistent surface finishes. This tool is intended for professional machinists and CNC operators working in production environments.

This end mill is suited for milling steel, stainless steel, cast iron, and hardened materials in both roughing and finishing operations. The AlTiN coating performs well at elevated cutting temperatures, making it appropriate for high-speed and dry or minimal-coolant machining strategies. It is used in vertical and horizontal machining centers where a 0.75-inch shank diameter toolholder is present. The Series UCDE designation places it within a Kennametal family designed for hard-material performance. Material grade KCPM15 supports use in ISO material groups P, M, K, and H.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating for high-temperature oxidation resistance and extended tool life
• 5 spiral flutes with variable index design to reduce chatter and vibration
• 38-degree helix angle promotes efficient chip flow and smooth cutting action
• Right-hand cut, right-hand flute configuration compatible with standard CNC spindle direction
• Non-centercutting geometry — not intended for direct plunge entry

Compatibility

Designed for use with standard 0.75-inch shank diameter toolholders in CNC machining centers. Rated for primary workpiece materials including steel, stainless steel, cast iron, and hardened materials corresponding to ISO material codes P, M, K, and H.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. The spindle must be fully stopped and the machine placed in a safe, locked-out state before changing tooling. Seat the shank fully into a clean, properly sized collet or toolholder and torque retention hardware per the toolholder manufacturer specifications. Because this end mill is non-centercutting, do not program direct plunge moves — use ramping or helical entry strategies instead.
