Accupro 12181547 Corner Radius End Mill 3/4 in 2 Flute Ticn

Product Description

The ACCUPRO 12181547 is a solid carbide corner radius end mill designed for precision milling operations in metal fabrication and machining environments. It features a 3/4 inch diameter, a 1-1/2 inch length of cut, and a 0.09 inch corner radius that reduces stress concentrations at the base of milled features. The micrograin carbide substrate delivers hardness and wear resistance, while the TiCN coating lowers friction and extends tool life in ferrous and non-ferrous materials. With a 40-degree helix angle, this single-end, centercutting tool evacuates chips efficiently and supports both plunge and peripheral cutting. It is intended for use by machinists and tooling specialists working in manual or CNC milling setups.

This end mill is suited for milling slots, pockets, and contoured profiles in production and job-shop environments. The corner radius geometry is particularly useful when machining radiused floor-to-wall transitions in pockets and cavities, reducing the need for secondary deburring or grinding. The right-hand flute direction and right-hand cutting orientation match standard CNC milling spindle configurations. It is appropriate for general-purpose machining of steel, stainless, cast iron, and similar materials where TiCN coating provides adequate thermal and abrasion protection.

Key Features

• 0.09 inch corner radius reduces stress risers and eliminates sharp inside corners in milled features
• TiCN coating provides wear resistance and reduced friction in ferrous and non-ferrous materials
• Micrograin solid carbide substrate for rigidity and edge retention at higher feed rates
• 40-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Centercutting design allows direct plunge entry into workpiece material
• Single-end configuration with right-hand cut and right-hand spiral flute direction

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide corner radius end mill for standard 3/4 inch collet or end mill holder tooling systems used in CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Secure the 3/4 inch shank in a properly sized collet, end mill holder, or shrink-fit holder and torque to the machine tool manufacturer's specification. Inspect the cutting edges and coating for chips or damage before use. Follow all applicable shop safety protocols and machine guarding requirements when changing or setting tooling.
