Accupro 12178828 Square End Mill 1/8 in 2 Flute Carbide

Product Description

The ACCUPRO 12178828 is a square-end, single-end solid carbide end mill designed for precision milling in ferrous and non-ferrous materials. It features a 1/8 inch cutting diameter, a 1 inch length of cut, and a 2-1/2 inch overall length with a matching 1/8 inch shank. The micrograin carbide substrate provides rigidity and wear resistance at elevated cutting speeds. An AlTiN coating adds thermal protection and reduces friction, extending tool life in dry or minimal-lubrication operations. This tool is well suited for machinists, toolmakers, and CNC operators working on close-tolerance features in production and job-shop environments.

This end mill is built for slotting, profiling, and contouring operations in CNC machining centers and manual mills. Its 40-degree helix angle promotes efficient chip evacuation and smooth cutting action, making it appropriate for hardened steels, stainless, cast iron, and similar materials. The centercutting geometry allows direct plunge entry, adding flexibility for pocket milling without a pre-drilled start hole. The small diameter and standard shank size make it a common choice for intricate detail work and tight-radius features.

Key Features

• Solid micrograin carbide construction for rigidity and extended tool life
• AlTiN coating for thermal resistance and reduced friction in dry cutting
• 40-degree helix angle for efficient chip evacuation and smooth cut surface
• Centercutting design allows direct plunge milling without a pilot hole
• Right-hand cut, right-hand spiral flute configuration for standard CNC spindle use
• 2-flute geometry balances chip clearance and cutting edge strength at small diameters

Compatibility

Designed as a standard-shank replacement end mill for CNC machining centers and manual knee mills accepting 1/8 inch collets or end mill holders. Consult machine spindle and collet specifications before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before loading or changing the tool. Secure the shank to the full recommended engagement depth in the collet or end mill holder to prevent pullout under cutting loads. Verify runout with a dial indicator after tool loading and before starting the cut, particularly given the tight shank diameter tolerances on this tool.
