Accupro 12177411 Square End Mill 3/8 Inch 6 Flute Carbide

Product Description

The ACCUPRO 12177411 is a solid carbide square end mill designed for high-performance milling in metal, alloy, and composite materials. It features a 3/8 inch cutting diameter, a 1 inch length of cut, and a 2-1/2 inch overall length. The 6-flute geometry with a 45-degree helix angle improves chip evacuation and surface finish at higher feed rates. Micrograin carbide construction delivers hardness and edge retention superior to cobalt or HSS tooling. This is a centercutting tool, allowing plunge entry as well as conventional peripheral milling. Right-hand cut and right-hand flute configuration matches standard spindle rotation on most CNC machining centers and manual mills.

This end mill is suited for finish milling, slotting, and profiling operations in ferrous and non-ferrous materials. The uncoated micrograin carbide substrate performs well in aluminum, brass, and mild steels where coating adhesion or heat buildup is a concern. The 3/8 inch shank diameter fits standard ER collets, end mill holders, and set-screw-style tool holders used on vertical machining centers, CNC routers, and manual knee mills. Machinists and toolroom operators working in job shop and production environments will find the 6-flute design effective for high-speed finishing passes with light radial engagement.

Key Features

• Solid micrograin carbide construction for extended tool life and edge stability
• 6-flute spiral geometry with 45-degree helix angle for improved chip flow and surface finish
• Centercutting design allows direct plunge milling without a pre-drilled entry hole
• Right-hand cut, right-hand flute configuration for standard spindle operation
• Uncoated finish suitable for non-ferrous materials and applications where coating is not preferred
• Mill diameter tolerance of +0.000 / -0.002 inches for consistent fitment and dimensional accuracy

Compatibility

Designed as an OEM-style replacement or standard tooling option for 3/8 inch ER collet chucks, end mill holders, and set-screw holders on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the spindle before loading or unloading the tool. Ensure the shank is fully seated and properly torqued in the tool holder per the holder manufacturer specifications. Verify runout at the tool tip with a dial indicator before beginning cuts to protect both the tool and the workpiece.
