Accupro 12182199 Square End Mill 3/4 in 3 Flute Carbide

Product Description

The ACCUPRO 12182199 is a solid carbide square end mill designed for precision milling operations in metal, composite, and hard material applications. With a 0.750 inch mill diameter, 1 inch length of cut, and a 40-degree helix angle, this tool delivers efficient chip evacuation and smooth cutting performance in a wide range of machining environments. The micrograin carbide construction provides hardness and edge retention suited to high-speed and demanding cuts. It features a right-hand cut and right-hand spiral flute geometry with center-cutting capability, allowing plunge entry as well as peripheral and slot milling. The stub-length profile adds rigidity for reduced deflection. Weight is 0.75 pounds.

This end mill is suited for use in CNC machining centers, vertical mills, and manual milling machines where a stub-length, three-flute tool is appropriate. The 3/4 inch shank diameter matches standard collet and end mill holder sizes common in both job shop and production environments. The uncoated finish makes it a straightforward choice for general-purpose ferrous and non-ferrous milling where coating compatibility or regrinding flexibility is a priority. Licensed machinists and toolroom technicians are the typical end users for this style of cutting tool.

Key Features

• 0.750 inch mill diameter with a tight tolerance of +0.000 / -0.002 inches for precise fitment
• Micrograin solid carbide construction for hardness and edge retention
• 40-degree helix angle spiral flute promotes efficient chip flow
• Center-cutting design allows direct plunge entry into workpiece
• Right-hand cut and right-hand flute for standard spindle rotation
• Stub-length OAL of 3 inches adds rigidity and reduces tool deflection

Compatibility

Designed as an OEM-style replacement or standard tooling option for 3/4 inch collet chucks, end mill holders, and milling arbors accepting a 0.750 inch shank diameter in CNC and manual milling applications.

Installation Notes

This end mill is installed by a qualified machinist or toolroom technician. Ensure the milling machine spindle is fully stopped and locked out before changing tooling. Use a properly sized collet or end mill holder torqued to the machine manufacturer's specification to prevent slippage. Inspect the cutting edges and shank for damage before each use; carbide is brittle and should not be dropped or struck against hard surfaces.
