Accupro 12183217 Corner Radius End Mill 3/16 in 4 Flute Ticn

Product Description

The ACCUPRO 12183217 is a solid carbide corner radius end mill designed for precision milling operations in metal fabrication and machining environments. With a 3/16 inch (0.1875 inch) mill diameter and a 0.060 inch corner radius, this tool produces smooth, radiused edges on workpiece corners, reducing stress concentrations and improving surface finish. The 40-degree helix angle promotes efficient chip evacuation and reduced cutting forces. A TiCN (Titanium Carbonitride) coating increases surface hardness and wear resistance, extending tool life across a range of ferrous and non-ferrous materials. This end mill is intended for use by machinists and CNC operators in production shop and job shop settings.

This tool suits applications requiring extra-long reach, with a 1-1/8 inch length of cut and a 3 inch overall length. The single-end, centercutting design allows plunge cutting in addition to peripheral and slot milling. Right-hand flute direction and right-hand cutting orientation are standard for conventional CNC vertical and horizontal milling setups. The micrograin carbide substrate supports consistent performance in tight-tolerance work where dimensional accuracy is critical.

Key Features

• 0.060 inch corner radius reduces stress risers and improves part finish on radiused profiles
• TiCN coating provides elevated surface hardness and extended tool life on hard materials
• 40-degree helix angle promotes aggressive chip evacuation and smooth cutting action
• Centercutting design enables direct plunge entry without a pre-drilled hole
• Extra-long length of cut (1-1/8 inches) allows reach into deep pockets and slots
• Micrograin solid carbide substrate delivers dimensional stability under high feed rates

Compatibility

Designed as an OEM-style solid carbide corner radius end mill suitable for standard 3/16 inch collet or end mill holder setups on CNC machining centers and manual mills.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for toolholder tightening and runout verification. Confirm the spindle and toolholder are clean and free of debris before seating the shank. Always power down and lock out the machine before changing tooling. Do not exceed the tool manufacturer recommended speeds and feeds for the workpiece material and coating type.
