Accupro EM15300801 Square End Mill 1/8 in 4 Flute Carbide

Product Description

The ACCUPRO EM15300801 is a solid carbide square end mill designed for precision milling operations in metal, composites, and other hard materials. With a 0.125-inch cutting diameter, a 0.625-inch length of cut, and a 2-inch overall length, this tool is built for tight-tolerance slotting, profiling, and plunging in confined workspaces. The ultra-micrograin carbide substrate provides edge strength and wear resistance, while the titanium aluminum nitride (TiAlN) coating extends tool life at elevated cutting temperatures. Four right-hand spiral flutes at a 30-degree helix angle promote efficient chip evacuation and smooth finishes. This end mill is centercutting, allowing direct plunge entry without a pre-drilled hole.

This end mill is suited for CNC machining centers, vertical mills, and manual knee mills used in job shops, tool rooms, and production environments. The 1/8-inch shank diameter is compatible with standard collets and end mill holders used in both small-format machining centers and benchtop CNC routers. It is a common choice for detail work, narrow slot milling, and finish passes on ferrous and non-ferrous metals. Machinists handling precision components, prototype parts, or die and mold work will find the compact geometry well suited to fine-feature applications.

Key Features

• Solid ultra-micrograin carbide construction for rigidity and edge retention
• TiAlN coating for extended tool life at high cutting temperatures
• 4 right-hand spiral flutes with 30-degree helix angle for efficient chip flow
• Centercutting design allows direct plunge milling without a pilot hole
• Right-hand cut and right-hand flute configuration for standard spindle direction
• Single-end tool with 0.625-inch length of cut and 2-inch overall length

Compatibility

Designed as a standard 1/8-inch shank square end mill compatible with collet chucks, ER collet systems, and end mill holders sized for 1/8-inch shanks on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist familiar with tool holding systems and runout tolerances. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank to the recommended gauge-line depth in the collet or holder and torque the retention hardware per the tool holder manufacturer specifications. Verify runout with a dial indicator before beginning a cut, as excessive runout at this diameter will significantly shorten tool life.
