Accupro 12183800 Square End Mill 9/16 in 5 Flute Carbide

Product Description

The ACCUPRO 12183800 is a solid carbide square end mill designed for high-performance milling in ferrous and non-ferrous metals. It features a 9/16-inch cutting diameter, a 1-1/2-inch length of cut, and a 3-1/2-inch overall length with a matching 9/16-inch shank diameter. The 5-flute geometry paired with a 45-degree helix angle promotes efficient chip evacuation and improved surface finish at higher feed rates. An AlTiN coating provides elevated heat resistance and extended tool life in dry or semi-dry cutting conditions. This end mill is centercutting, allowing direct plunge entry into the workpiece. It is intended for use by machinists and CNC operators in precision machining environments.

This end mill is suited for peripheral milling, slotting, and plunge operations in a range of materials where a carbide substrate and AlTiN finish deliver a clear advantage over HSS tooling. The right-hand cut and right-hand spiral flute configuration is standard for conventional CNC machining centers and manual mills. The regular-length profile makes it a practical choice for general-purpose milling where extended reach is not required. Micrograin carbide construction supports tighter tolerances and longer run intervals between tool changes.

Key Features

• Solid micrograin carbide substrate for rigidity and wear resistance
• AlTiN finish for high-heat performance in ferrous cutting applications
• 5-flute design increases feed rate capability and improves surface finish
• 45-degree helix angle promotes smooth cutting action and efficient chip flow
• Centercutting geometry allows direct plunge milling without pre-drilling
• Right-hand cut, right-hand flute spiral configuration for standard CNC setups

Compatibility

Designed as an OEM-style replacement or direct-fit cutting tool for CNC machining centers and manual mills accepting a 9/16-inch straight shank end mill.

Installation Notes

Installation should be performed by a qualified machinist familiar with CNC tooling and collet or end mill holder systems. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill. Verify collet size matches the 9/16-inch shank diameter and that the tool is seated to the appropriate gauge length before tightening. Inspect runout after seating to confirm the tool is properly secured before initiating a cut.
