Accupro 12183721 Corner Radius End Mill 1/2 in 4 Flute

Product Description

The ACCUPRO 12183721 is a solid carbide corner radius end mill designed for precision milling operations in metal cutting and machining applications. It features a 1/2 inch diameter, a 1-1/2 inch length of cut, and a 0.02 inch corner radius that reduces stress concentrations at the base of milled features. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. With four flutes and a bright/uncoated finish, this tool is suited for high-precision work where dimensional accuracy is critical. Machinists and CNC operators working in job shops, tool rooms, and production environments are the primary users.

This end mill is appropriate for use on CNC machining centers and manual mills handling ferrous and non-ferrous materials where a corner radius profile is required. The extra-long overall length of 6 inches extends reach for deep-pocket and long-reach milling scenarios. Its centercutting design allows direct plunge entry, adding versatility to slotting, profiling, and ramping operations. The right-hand flute direction and right-hand cutting direction are standard for conventional CNC setups.

Key Features

• 0.02 inch corner radius reduces tool stress and improves part surface finish at pocket corners
• 4-flute, right-hand spiral design supports efficient chip removal and stable cutting
• 40-degree helix angle promotes smooth cutting action and reduces chatter
• Centercutting geometry allows plunge milling and ramping entry
• Extra-long 6 inch overall length provides extended reach for deep-pocket work
• Micrograin solid carbide construction delivers hardness and wear resistance

Compatibility

Designed as an OEM-style solid carbide corner radius end mill for use in standard 1/2 inch collet or end mill holders on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Secure the shank fully in a clean, properly sized collet or end mill holder to the recommended engagement depth before tightening. Inspect the tool and holder for runout before beginning a cut. Follow all machine guarding and personal protective equipment requirements applicable to machining operations.
