Accupro 12182289 Square End Mill 1/2 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 12182289 is a solid carbide square end mill designed for precision material removal in milling operations. Built from micrograin carbide, it offers the rigidity and wear resistance required for demanding cutting applications in ferrous and non-ferrous materials. The 3-flute geometry with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. At 0.5 inches in diameter with a 1-inch length of cut and 4-inch overall length, this is a long-length configuration suited for applications requiring extended reach into pockets or slots. It is installed and operated by machinists and tooling specialists in job shop and production environments.

This end mill is well suited for slot milling, profiling, and pocket operations on machining centers and manual mills. The long length of cut — 1 inch — allows access to deeper features compared to standard-length end mills of the same diameter. The centercutting design permits plunge entry directly into a workpiece, adding operational flexibility. Right-hand cut and right-hand flute configuration align with conventional spindle rotation on standard vertical and horizontal machining centers.

Key Features

• Solid micrograin carbide construction for rigidity and extended tool life
• 3-flute design with 40-degree helix angle for efficient chip evacuation
• Centercutting geometry allows direct plunge entry into workpiece
• Long-length configuration with 1-inch length of cut for deeper feature access
• Right-hand cut and right-hand flute for standard spindle compatibility
• Uncoated finish suitable for use with appropriate cutting fluids

Compatibility

Designed as a direct-fit tooling option for standard 1/2-inch collets and end mill holders used on vertical machining centers, CNC mills, and manual knee mills requiring a long-length, 3-flute square end mill.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. The end mill must be secured in a properly sized collet or end mill holder to the torque specification required by the toolholder manufacturer — do not estimate by hand feel alone. Confirm spindle rotation direction matches the right-hand cut designation before running. Inspect the cutting edges and shank for damage before each use; carbide is brittle and can chip if dropped or improperly stored.
