Accupro 12183887 Square End Mill 3/4 Inch 6 Flute Carbide

Product Description

The ACCUPRO 12183887 is a solid carbide square end mill designed for precision milling in demanding machining environments. With a 3/4-inch cutting diameter, 6-flute spiral geometry, and a 40-degree helix angle, this tool delivers smooth chip evacuation and stable cutting performance in ferrous and non-ferrous materials. The micrograin carbide substrate provides hardness and wear resistance suited for high-speed applications. At 5 inches overall length with a 2-1/4-inch length of cut, this falls into the long-length category, making it useful for applications requiring extended reach into deep pockets or slots. It is an uncoated, centercutting, right-hand cut and right-hand flute configuration.

This end mill is used in CNC machining centers and manual mills for slotting, profiling, and peripheral milling operations. Its long length of cut is well suited for deep-cavity work in mold making, die work, and general precision part manufacturing. The centercutting design allows it to plunge directly into the workpiece, adding versatility for interpolation and ramping operations. Machinists and tooling professionals handling production or job-shop work will find this tool appropriate for a wide range of steel, aluminum, and similar workpiece materials.

Key Features

• 6-flute spiral design improves chip removal and surface finish at higher feed rates
• 40-degree helix angle reduces cutting forces and vibration in deep-cut applications
• Centercutting geometry allows direct plunge entry without a pilot hole
• Micrograin solid carbide construction for extended tool life in high-speed milling
• Long-length classification with 2-1/4-inch length of cut for deep pocket access
• Right-hand cut and right-hand flute, compatible with standard spindle rotation

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard 3/4-inch ER or shell-mill collet chucks used in CNC and manual milling machines requiring a 3/4-inch shank end mill.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the tool holder. Verify collet or chuck bore is clean and within tolerance before seating the shank to maintain runout accuracy. Follow machine manufacturer guidelines and applicable shop safety standards when setting tool length offsets and spindle speeds.
