Accupro 12177084 Square End Mill 3/8 in 4 Flute Carbide

Product Description

The ACCUPRO 12177084 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. Built from micrograin carbide stock, it delivers the hardness and edge retention needed for ferrous and non-ferrous materials. The 4-flute, spiral geometry with a 40-degree helix angle promotes efficient chip evacuation and smooth surface finishes. At 0.375 inches in diameter with a 0.875-inch length of cut, this end mill suits slotting, profiling, and peripheral milling operations. The uncoated finish makes it a reliable general-purpose option where coating is not required. Installed by CNC machinists and manual mill operators alike.

This end mill is suited for production and job-shop environments running vertical or horizontal milling machines and CNC machining centers. Its centercutting capability allows plunge entry directly into the workpiece without a pre-drilled pilot hole, adding flexibility for complex toolpaths. The right-hand cut and right-hand flute configuration is standard for conventional and climb milling setups. With a 0.375-inch shank diameter, it seats directly in standard ER or end mill holders sized for 3/8-inch tooling.

Key Features

• Solid micrograin carbide construction for edge hardness and wear resistance
• 4-flute spiral geometry with 40-degree helix angle for efficient chip flow and surface finish
• Centercutting design allows direct plunge entry without pilot hole
• Right-hand cut and right-hand flute for standard milling machine setups
• Uncoated - suitable for general-purpose use and re-sharpening
• Matched shank and cutting diameter at 0.375 inches for straightforward tool holding

Compatibility

Designed as an OEM-style replacement or direct-use end mill for milling machines and CNC machining centers accepting 3/8-inch shank tooling in standard ER collets or end mill holders.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully powered down and locked out per shop safety procedures. Verify tool holder runout before operation, as excessive runout accelerates edge wear and degrades surface finish. Tighten collet or set-screw holders to the tool holder manufacturer's specified procedure. Confirm cutting parameters - speed, feed, and depth of cut - are appropriate for the workpiece material before engaging the cut.
