Accupro 12182983 Corner Radius End Mill 1 in 4 Flute Ticn

Product Description

The ACCUPRO 12182983 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and non-ferrous materials. It features a 1 inch cutting diameter, a 2.25 inch length of cut, and a 0.06 inch corner radius that reduces stress concentration at the cutting edge and extends tool life in demanding applications. The TiCN (titanium carbonitride) coating adds surface hardness and wear resistance compared to uncoated carbide. Micrograin carbide construction provides the toughness needed for interrupted cuts and high-feed passes. This tool is used by machinists and tooling specialists in job shops, production facilities, and maintenance machining environments.

This end mill is suited for profiling, slotting, and contouring operations where a controlled corner radius is required to blend floor-to-wall transitions. The long-length configuration, with a 5 inch overall length, provides extended reach for deeper pockets and tall workpiece setups. Single-end, centercutting geometry allows plunge entry. Right-hand flute direction and right-hand cutting orientation are standard for conventional vertical and horizontal milling machine spindles.

Key Features

• 1 inch cutting diameter with 2.25 inch length of cut for deep-reach profiling
• 0.06 inch corner radius reduces edge chipping and improves surface finish at corners
• 4-flute spiral geometry for balanced chip evacuation and feed rate capacity
• TiCN coating increases surface hardness and wear resistance for extended tool life
• Micrograin solid carbide substrate for rigidity and resistance to deflection
• Centercutting design allows direct plunge entry without a pre-drilled pilot hole

Compatibility

Designed as an OEM-style replacement or direct tooling selection for milling machines accepting a 1 inch straight shank end mill holder or collet chuck.

Installation Notes

Installation requires a milling machine spindle with a matching 1 inch end mill holder, collet, or hydraulic chuck rated for the tool shank diameter tolerance range of -0.0001 to -0.0004 inches. Ensure the spindle is fully powered down and locked before mounting or removing tooling. Confirm runout with a dial indicator after seating the tool to verify proper chuck engagement before initiating a cut. Follow applicable shop safety standards and machine manufacturer guidelines for speeds, feeds, and depth of cut based on workpiece material.
