Accupro 12180762 Square End Mill 1 Inch 5 Flute Carbide

Product Description

The ACCUPRO 12180762 is a solid carbide square end mill designed for precision metal removal in milling operations. It features a 1 inch cutting diameter, a 1-3/4 inch length of cut, and a 4 inch overall length with a 1 inch shank diameter. The tool carries an AlTiN finish for elevated heat resistance and wear life in demanding cutting environments. A 40-degree helix angle and spiral flute geometry promote efficient chip evacuation and reduced cutting forces. This end mill is intended for use by machinists and tool-and-die professionals operating CNC mills, VMCs, and manual knee mills.

This end mill suits general-purpose and finish milling applications in ferrous and non-ferrous materials where tight tolerances and surface finish are priorities. The centercutting design allows plunge entry, adding versatility for pocketing, slotting, and contouring operations. The 5-flute configuration supports higher feed rates compared to 4-flute tooling in the same diameter range. It is suited for medium-to-high material removal passes in production or job-shop environments where solid carbide rigidity outperforms high-speed steel alternatives.

Key Features

• 1 inch cutting diameter with mill diameter tolerance of +0.000 / -0.002 inches
• 5-flute spiral geometry for increased feed rate capacity and improved finish
• 40-degree helix angle promotes chip flow and reduces heat buildup at the cutting edge
• AlTiN coating provides oxidation resistance and extends tool life in ferrous materials
• Centercutting design allows direct plunge entry for pocketing operations
• Micrograin solid carbide substrate delivers edge strength and dimensional stability
• Variable index flute spacing reduces chatter and vibration during cut

Compatibility

Designed as an OEM-style replacement and standard-geometry end mill for use in CNC and manual milling machines accepting a 1 inch straight shank with a shank diameter tolerance of -0.0001 / -0.0004 inches.

Installation Notes

Installation is performed by machinists or CNC setup technicians. Secure the shank in a properly sized collet chuck, end mill holder, or Weldon-style holder rated for the 1 inch shank diameter, and verify runout with a dial indicator before cutting. Power down and lock out the spindle before tool changes per machine-specific lockout/tagout procedures. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and cut depth.
