Accupro 12182272 Square End Mill 1/8 in 3 Flute Carbide

Product Description

The ACCUPRO 12182272 is a solid carbide square end mill designed for precision milling operations in metal, composite, and engineered materials. Built from micrograin carbide with a TiCN (Titanium Carbonitride) finish, this three-flute tool runs right-hand cut and right-hand spiral flute geometry with a 40-degree helix angle. The long-length configuration delivers a 3/4-inch length of cut from a 1/8-inch diameter, making it well suited for deep-reach slotting and profiling in tight geometries. Centercutting capability allows plunge entry without a pre-drilled start hole. Machinists and tool-and-die professionals rely on this style of end mill for close-tolerance finishing work.

This end mill is sized for small-diameter, precision work in CNC machining centers, manual mills, and high-speed spindle applications. The 1/8-inch shank fits standard ER collets and end mill holders common in both production shops and toolroom environments. The long overall length of 3 inches supports reach into recessed features or multi-axis setups where tool clearance is a factor. The TiCN coating reduces friction and extends tool life compared to uncoated carbide when cutting ferrous and non-ferrous materials.

Key Features

• Micrograin solid carbide construction for rigidity and edge retention
• TiCN finish improves wear resistance and reduces built-up edge
• 40-degree helix angle promotes chip evacuation and smooth cutting action
• Centercutting design permits direct plunge milling without pilot hole
• Right-hand cut, right-hand flute — standard orientation for conventional and climb milling
• Long-length configuration provides extended reach for deep-pocket and recessed-feature work

Compatibility

Designed as a standard 1/8-inch shank square end mill compatible with ER collet chucks, end mill holders, and shrink-fit tooling systems that accept 1/8-inch diameter shanks on CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is in an energy-isolated state before loading or changing tooling. Verify collet or holder runout before first cut, as shank diameter tolerance on this tool is -0.0001 to -0.0004 inches and excess runout will accelerate edge wear. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and coating type.
