Accupro 12181733 Square End Mill 0.5 in 2 Flute Solid Carbide Altin

Product Description

The ACCUPRO 12181733 is a single-end, square-profile solid carbide end mill designed for precision metal removal in milling operations. The tool measures 0.5 inches in diameter with a 2-inch length of cut and a 4-inch overall length, making it a long-series configuration suitable for applications requiring extended reach into deep pockets or slots. The 40-degree spiral helix angle promotes aggressive chip evacuation and smooth cutting action. An AlTiN (Aluminum Titanium Nitride) coating provides thermal resistance and extended tool life when cutting ferrous and hardened materials. Licensed machinists and CNC operators are the primary users of this tool.

This end mill is suited for use on vertical and horizontal machining centers, CNC mills, and manual knee mills where a 0.5-inch shank is accepted. The long flute length supports full-depth slotting, profiling, and pocket milling in steel, stainless steel, cast iron, and similar hard materials. The centercutting design allows plunge entry directly into the workpiece without a pre-drilled pilot hole. Right-hand cut and right-hand flute geometry match standard spindle rotation on most commercial machine tools.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating extends tool life by reducing heat transfer into the carbide substrate
• 40-degree helix angle promotes efficient chip flow and reduces cutting forces
• Centercutting geometry allows direct plunge milling without a pilot hole
• Long-series flute length of 2 inches supports deep pocket and slot milling
• Right-hand cut and right-hand spiral flute match standard CNC spindle configurations

Compatibility

Designed as an OEM-style replacement or direct application tool for CNC machining centers and manual mills accepting a 0.5-inch straight shank end mill holder or collet.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. The shank must be fully seated and properly torqued in a clean, undamaged collet or end mill holder before spindle engagement. Inspect the collet and holder for runout before use, as excessive runout accelerates tool wear and degrades surface finish. Always confirm spindle rotation direction matches the right-hand cut orientation of this tool before initiating a cut.
