Accupro 12180376 Corner Rounding End Mill 4 Flute Solid Carbide

Product Description

The ACCUPRO 12180376 is a double-end corner rounding end mill designed for precision edge profiling on ferrous and non-ferrous metals. Built from solid carbide with a TiCN (Titanium Carbonitride) coating, it delivers extended tool life and heat resistance in demanding milling applications. The 4-flute geometry provides a smooth finish and efficient chip evacuation. At 0.035 inches radius and 3/16 inches diameter, this tool is suited for fine corner breaks and edge blending where tight tolerances are required. Licensed machinists and tool-and-die professionals are the primary users of this end mill.

This end mill is used in CNC milling centers and manual knee mills for corner rounding operations on steel, stainless, and hardened alloys. The double-end design maximizes the usable life of each tool, making it practical for production environments. With a 3/16 inches shank diameter, it fits standard ER collet chucks and end mill holders commonly found in machine shops. The 2 inches overall length keeps overhang minimal, improving rigidity during light finishing cuts.

Key Features

• Double-end design doubles usable cutting life per tool
• Solid carbide construction resists wear and deflection under load
• TiCN coating improves surface hardness and reduces friction for longer run times
• 4-flute configuration supports smooth corner rounding and clean edge finishes
• Right-hand cutting and right-hand flute direction for standard spindle operation
• Compact 3/16 inches diameter suits fine detail work and tight-clearance setups

Compatibility

Designed as an OEM-style replacement or direct-use corner rounding end mill for standard 3/16 inches shank ER collet chucks and end mill holders used in CNC and manual milling applications.

Installation Notes

Installation should be performed by a qualified machinist. Power down and lock out the machine spindle before changing tooling. Secure the shank fully within the collet or holder to the recommended grip length and verify runout before engaging a cut. Avoid side-loading the tool beyond its rated geometry, as solid carbide is brittle and susceptible to chipping under impact or excessive lateral force.
