Accupro 12183454 Corner Radius End Mill 3/16 in 4 Flute

Product Description

The ACCUPRO 12183454 is a solid carbide corner radius end mill designed for precision milling operations in metal cutting and machining applications. It features a 3/16 inch diameter with a 0.03 inch corner radius, delivering controlled edge blending and reduced stress concentration at part corners. With 4 flutes and a 40-degree helix angle, this single-end, centercutting tool handles both plunging and peripheral cuts. The micrograin carbide construction provides hardness and wear resistance suitable for demanding shop environments. This tool is installed and used by machinists and CNC operators working in production or job-shop settings.

This end mill is suited for milling slots, pockets, and contoured features in ferrous and non-ferrous materials where a small corner radius is required for stress relief or part geometry. The long-length configuration with a 1 inch length of cut and 4 inch overall length provides reach for deeper features. The bright uncoated finish makes it a straightforward choice for general-purpose applications where specialized coatings are not required. Right-hand cutting and right-hand flute direction are standard for conventional CNC and manual milling setups.

Key Features

Compatibility

Designed as an OEM-style replacement or standard tooling selection for CNC machining centers and manual milling machines accepting 3/16 inch shank end mills with right-hand cutting direction.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe, powered-down state before changing tooling. Seat the 3/16 inch shank securely in a compatible collet or end mill holder and verify runout before beginning a cut. Follow machine manufacturer torque specifications for collet nuts and tool holders.
