Accupro 95168360 Square End Mill 3/8 in 4 Flute Carbide

Product Description

The ACCUPRO 95168360 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous metal applications. It features a 3/8 inch mill diameter with a 1 inch length of cut, a 2.5 inch overall length, and a 3/8 inch shank diameter. The variable helix geometry reduces harmonic vibration during cut, improving surface finish and tool life. An nACRo coating provides high-temperature oxidation resistance, making this end mill well suited for harder workpiece materials. The micrograin carbide substrate supports tighter tolerances and edge integrity at higher feed rates. Machinists and toolroom technicians are the primary users.

This end mill is used in vertical machining centers, CNC knee mills, and manual milling machines for slotting, profiling, and peripheral milling operations. The single-end, center-cutting configuration allows plunge entry, side milling, and ramping. The right-hand cut and right-hand flute spiral are standard for conventional CNC toolpaths. It is suited for production runs and precision tool-and-die work where close dimensional control is required. The 4-flute spiral design supports higher feed rates compared to 2-flute end mills while maintaining chip evacuation in shallow-to-moderate depth-of-cut applications.

Key Features

• Variable helix design reduces chatter and harmonic vibration during milling
• nACRo coating provides oxidation resistance and extends tool life in harder materials
• Micrograin solid carbide substrate supports tight tolerances and sharp edge retention
• Center-cutting geometry allows plunge, ramp, and helical interpolation entry
• 4-flute spiral configuration balances feed rate capability with chip clearance
• Mill diameter tolerance of plus 0.000 and minus 0.002 inches for dimensional accuracy

Compatibility

Designed as a direct-fit replacement for standard 3/8 inch shank square end mill holders, collet chucks, and ER-style collet systems used in CNC and manual milling equipment.

Installation Notes

Installation is performed by machinists or toolroom technicians familiar with CNC or manual milling equipment. Secure the shank fully within the tool holder to the recommended gauge-line depth before tightening. Inspect the collet or end mill holder for runout before use, as excessive runout accelerates edge wear and reduces dimensional accuracy. Do not exceed the tool's rated length of cut when programming axial depth of cut.
