Accupro 95169803 Square End Mill 1/8 in 5 Flute Solid Carbide

Product Description

The ACCUPRO 95169803 is a 5-flute, solid carbide square end mill designed for high-performance milling in demanding machining environments. Built from micrograin carbide stock and coated with AlTiCrN for heat and wear resistance, this tool handles aggressive cutting in hardened steels, stainless alloys, and other difficult-to-machine materials. The 38-degree helix angle promotes efficient chip evacuation and smooth cutting action, while the variable index flute spacing reduces chatter and vibration during full-slot and peripheral milling passes. At 0.125 inches in diameter with a 0.1875-inch length of cut, this is a precision tool suited for fine-detail work and tight-tolerance features.

This end mill is suited for CNC machining centers, vertical mills, and high-speed spindle setups used in tool rooms, production shops, and die-and-mold operations. The extended reach geometry, with a reach length of 0.375 inches, allows access to deeper pockets and stepped features without sacrificing rigidity. Its single-end configuration makes it a standard replacement consumable for shops running 5-flute finishing strategies or high-efficiency milling toolpaths.

Key Features

• AlTiCrN coating provides high-temperature hardness and oxidation resistance for dry and semi-dry cutting
• 5-flute design increases feed rate potential compared to standard 4-flute tools at the same diameter
• 38-degree helix angle improves chip flow and reduces cutting forces
• Variable index fluting minimizes harmonic vibration and chatter
• Micrograin carbide substrate offers consistent edge integrity and extended tool life
• Center-cutting capable, allowing plunge entry into workpiece material

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill for standard 1/8 inch collet chucks and end mill holders on CNC and manual milling equipment.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use a calibrated torque wrench with the appropriate collet nut wrench to secure the shank in a clean, undamaged collet. Inspect the collet bore and tool shank for chips or contamination before seating to avoid runout that can accelerate tool wear or cause breakage on small-diameter carbide tools.
