Accupro 12185222 Square End Mill 0.2756 in 4 Flute Carbide

Product Description

The ACCUPRO 12185222 is a solid carbide square end mill designed for precision milling operations in metal fabrication and machining environments. With a 0.2756-inch (7.00 mm) mill diameter and a 0.4724-inch (12.00 mm) length of cut, this double-end tool delivers consistent performance in stub-length applications. The 40-degree helix angle and spiral flute geometry promote efficient chip evacuation and reduce cutting forces. A TiCN finish increases surface hardness and wear resistance, extending tool life in demanding materials. This end mill is installed and operated by machinists and CNC tooling professionals in production and job shop settings.

This end mill is suited for milling operations on ferrous and non-ferrous metals where a compact stub-length profile is required. The centercutting design allows for direct plunge entry as well as conventional side milling passes. Right-hand cut and right-hand flute orientation make it compatible with standard CNC machining center spindles. The 8.00 mm (approximately 0.315-inch) shank diameter fits standard collet and toolholder systems commonly found in vertical and horizontal machining centers.

Key Features

• Solid carbide micrograin construction for rigidity and edge retention
• TiCN coating for increased wear resistance and reduced friction at the cutting edge
• 4-flute design provides a strong core and smooth finish cuts
• 40-degree helix angle promotes efficient chip flow and reduced cutting pressure
• Double-end configuration maximizes tool life per unit
• Centercutting capability allows plunge milling without a pre-drilled entry point
• Stub length profile provides added rigidity in tight-clearance setups

Compatibility

Designed as a standard stub-length square end mill with an 8.00 mm shank diameter, compatible with ER-style collets, shrink-fit holders, and other toolholding systems sized for that shank diameter on CNC mills and machining centers.

Installation Notes

This end mill is installed by machinists using appropriate collet chucks or hydraulic toolholders torqued to the toolholder manufacturer specifications. The machine spindle should be confirmed at a full stop before tool changes. Verify runout with a dial indicator after clamping to ensure concentricity and prevent premature edge wear. Follow all machine guarding and PPE requirements per shop safety standards when operating.
