Accupro 14797046 Square End Mill 0.027 in 4 Flute Altin

Product Description

The ACCUPRO 14797046 is a solid carbide square end mill designed for precision milling of ferrous and hard materials in CNC machining applications. With a 0.027-inch cutting diameter and a 0.041-inch length of cut, this is a micro-geometry tool suited for fine-detail work, slotting, and profiling in tight geometries. The AlTiN coating provides heat resistance and extended tool life at elevated cutting speeds. The 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. Machinists and tool-and-die professionals install this cutter in CNC mills and machining centers requiring small-diameter, high-precision end milling.

This end mill is appropriate for use in precision machining environments where tight tolerances and small feature sizes are required. It is well-suited for profiling, slotting, and finish milling in hardened steels, stainless steels, and similar difficult-to-machine alloys. The right-hand cutting direction and right-hand flute spiral make it compatible with standard CNC spindle rotation. Its 1/8-inch shank diameter fits standard collet systems commonly found on vertical machining centers and CNC routers equipped for micro tooling.

Key Features

• 0.027-inch cutting diameter with mill diameter tolerance of +0.0000 / -0.0010 inches for consistent sizing
• AlTiN coating for elevated-temperature performance and extended tool life on hard materials
• 4-flute, right-hand spiral configuration for improved surface finish and material removal rate
• 30-degree helix angle promotes efficient chip evacuation during slotting and profiling
• Micrograin solid carbide construction for rigidity and edge retention at micro diameters
• Center-cutting capable, allowing plunge entry as well as peripheral milling

Compatibility

Designed as an OEM-style replacement or direct-fit tool for CNC milling applications requiring a 1/8-inch shank, 0.027-inch diameter, 4-flute square end mill in the ASQSC4-AT-CC-30H series.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the spindle before installing or changing tooling. Seat the 1/8-inch shank fully into the collet or tool holder and torque the collet nut according to the collet manufacturer specifications. Verify runout with a dial indicator before beginning production cuts, as runout is especially critical at this diameter.
