Accupro 12177076 Square End Mill 7/32 in 4 Flute Carbide

Product Description

The ACCUPRO 12177076 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. Built from micrograin carbide, it delivers the hardness and edge retention needed for cutting ferrous and non-ferrous materials. The 7/32 inch (0.2188 inch) cutting diameter pairs with a 4-flute, spiral-flute geometry and a 40-degree helix angle to balance chip evacuation with surface finish quality. At 2-1/2 inches overall length with a 5/8 inch length of cut, this end mill fits standard CNC machining centers and manual mills. It is centercutting, allowing direct plunge entry. Shank diameter is 1/4 inch. This tool is uncoated and runs right-hand cut with right-hand flute direction.

This end mill is suited for slot milling, profiling, and peripheral milling operations in shop and production environments. The micrograin carbide substrate handles both light finishing passes and moderate material removal rates. The 40-degree helix angle makes it well-suited for aluminum, plastics, and softer steels where smooth chip flow is a priority. Machinists, tool-and-die technicians, and CNC operators working on precision components will find this tool appropriate for tight-tolerance work given the mill diameter tolerance of plus 0.001 inch and minus 0.000 inch.

Key Features

• Micrograin solid carbide construction for hardness and edge retention
• 4-flute spiral geometry with 40-degree helix angle for efficient chip evacuation
• Centercutting design allows direct plunge milling without a pilot hole
• Right-hand cut and right-hand flute for standard spindle operation
• Mill diameter tolerance of plus 0.001 inch / minus 0.000 inch for precise fitment
• Uncoated finish suitable for a wide range of general-purpose milling applications

Compatibility

Designed as a direct-fit replacement or standard tooling option for CNC machining centers, knee mills, and manual milling machines accepting a 1/4 inch straight shank. No specific OEM compatibility was stated in the product data.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use a properly sized collet or end mill holder matching the 1/4 inch shank diameter to avoid runout. Verify tool projection and length of cut against the programmed depth to prevent overloading the flutes during operation.
