Accupro 12183878 Square End Mill 3/8 in 6 Flute Solid Carbide

Product Description

The ACCUPRO 12183878 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. Built with 6 flutes and a 40-degree helix angle, this centercutting tool delivers efficient chip evacuation and smooth surface finishes in a wide range of profiling, slotting, and peripheral milling applications. The micrograin carbide construction provides hardness and wear resistance suited to demanding production environments. With a 3/8 inch mill diameter and a 1-1/8 inch length of cut, it fits standard toolholding systems and is well-suited for both CNC machining centers and manual milling machines. Machinists and tool-and-die professionals select this geometry for its balance of rigidity and reach.

This end mill is classified as a long-length tool with a 3-inch overall length, making it appropriate for applications requiring extended reach into pockets, slots, or stepped features. The bright uncoated finish makes it a practical choice for aluminum, brass, copper, plastics, and other non-ferrous materials where coatings are unnecessary or undesirable. Right-hand cutting and right-hand flute direction are standard for conventional CNC spindle setups. It is sold individually and packaged as a single unit.

Key Features

• 6-flute geometry with 40-degree helix angle for improved surface finish and chip flow
• Centercutting design allows plunge entry directly into workpiece material
• Micrograin solid carbide construction for hardness and extended tool life
• Bright uncoated finish suited to non-ferrous and non-metallic workpiece materials
• Long-length classification with 3-inch overall length for extended reach applications
• Right-hand cut and right-hand spiral for use with standard CNC and manual milling spindles

Compatibility

Designed as a direct-fit replacement or standard tooling selection for 3/8 inch diameter collet chucks, end mill holders, and shrink-fit toolholders used in CNC machining centers and conventional vertical milling machines.

Installation Notes

Installation and tool changes should be performed with the machine spindle fully stopped and the control placed in a safe, locked-out state per applicable shop safety procedures. Ensure the shank is clean and fully seated in the toolholder before tightening. Verify runout with a dial indicator after clamping, particularly for tight-tolerance finishing operations. Follow machine manufacturer and tooling supplier guidelines for speeds and feeds appropriate to the workpiece material.
