Accupro 12181534 Corner Radius End Mill 3/4 in 2 Flute Carbide

Product Description

The ACCUPRO 12181534 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and non-ferrous materials. Built from micrograin carbide and left in a bright, uncoated finish, this single-end tool features a 0.02-inch corner radius, a 3/4-inch cutting diameter, and a 40-degree helix angle. With 2 flutes and a centercutting design, it is suited for plunge cuts, slot milling, and peripheral milling where a controlled edge radius is required to reduce chipping and improve surface finish. Machinists and tool and die professionals rely on this geometry for finishing passes on hardened and difficult materials.

This end mill is suited for use in vertical machining centers, CNC mills, and manual knee mills where a 3/4-inch shank holder is available. The 1-1/2-inch length of cut accommodates medium-depth pocketing and profiling operations. The right-hand cutting direction and right-hand flute spiral are standard for conventional and climb milling setups. Its extended 4-inch overall length provides clearance in deep-cavity or tall-workpiece applications without requiring a specialized holder extension.

Key Features

• Micrograin solid carbide construction for rigidity and edge retention
• 0.02-inch corner radius reduces stress concentration and edge chipping at the tool tip
• 40-degree helix angle promotes smooth chip evacuation and reduces cutting forces
• Centercutting design allows direct plunge entry into workpiece material
• Bright, uncoated finish compatible with a wide range of cutting fluids and materials
• Right-hand cut and right-hand spiral for standard CNC and manual mill setups

Compatibility

Designed as a standard 3/4-inch shank corner radius end mill compatible with 3/4-inch collet chucks, end mill holders, and shrink-fit tooling systems used in CNC and manual milling applications.

Installation Notes

Installation should be performed by a qualified machinist following the tool holder manufacturer's torque and runout specifications. Ensure the machine spindle is fully stopped and locked before inserting or removing the end mill. Confirm shank seating depth meets the minimum engagement requirement of the holder to prevent pullout under load. Inspect the cutting edges for chips or damage before each use and replace the tool if edge integrity is compromised.
