Accupro 12182484 Square End Mill 19/64 in 4 Flute Carbide

Product Description

The ACCUPRO 12182484 is a solid carbide square end mill designed for precision milling operations in metal, composites, and engineering plastics. Built from micrograin carbide, it delivers tight tolerances and edge retention across a range of cutting applications. The 19/64-inch (0.2969-inch) diameter tool features four spiral flutes with a 40-degree helix angle, promoting efficient chip evacuation and smooth cutting action. The centercutting geometry allows plunge entry as well as conventional peripheral milling. Right-hand cut and right-hand flute orientation are standard. This tool is uncoated and runs in the regular-length configuration.

This end mill suits job shop machinists, tool-and-die makers, and production floor operators working on CNC machining centers and manual mills. The 3/4-inch length of cut supports shoulder milling, slotting, and profiling in shallow-to-medium-depth features. The 5/16-inch shank diameter fits standard ER and straight-bore collet systems commonly found in vertical machining centers and high-speed spindles. Typical materials include aluminum alloys, mild steel, and non-ferrous metals where an uncoated carbide tool is preferred.

Key Features

• Micrograin solid carbide construction for superior edge retention and rigidity
• Four spiral flutes with 40-degree helix angle for efficient chip evacuation
• Centercutting design allows direct plunge entry without pre-drilling
• Right-hand cut and right-hand flute orientation for standard CNC and manual mill setups
• Mill diameter tolerance of +0.000 / -0.002 inches for consistent fit and finish
• Uncoated finish suited for dry cutting or applications where coating is not required

Compatibility

Designed as a standard replacement or stocking end mill for CNC machining centers and manual milling machines accepting a 5/16-inch straight shank via ER collet, set-screw holder, or equivalent toolholding system.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully powered down and at rest before inserting or removing the tool from the holder. Verify collet size matches the 5/16-inch shank diameter and that the tool is seated to the correct gauge length before tightening. Inspect the cutting edges for chips or wear before each use, as carbide tools can fracture if run damaged.
