Accupro 12183235 Corner Radius End Mill 1/4 in 4 Flute Ticn

Product Description

The ACCUPRO 12183235 is a solid carbide corner radius end mill designed for precision milling applications in ferrous and hardened materials. Built from micrograin carbide and coated with titanium carbonitride (TiCN), this tool delivers extended wear resistance and edge retention in demanding cutting environments. It features a 1/4 inch mill diameter, a 1-1/2 inch length of cut, and a 0.015 inch corner radius that reduces stress concentration at the cutting edge. The 4-inch overall length and extra-long length type make it suitable for deep-pocket and difficult-reach milling operations. Machinists and tool-and-die professionals working with CNC mills and machining centers are the primary users.

This end mill is suited for milling applications that require a controlled corner radius to prevent sharp-corner cracking in workpieces or molds. The TiCN coating performs well in cast iron, alloy steels, and stainless steel applications. The single-end, centercutting design allows plunge entry as well as conventional and climb milling. The extra-long configuration addresses setups where standard-length tooling cannot reach the cut depth required.

Key Features

• Micrograin solid carbide substrate for improved toughness and edge retention
• TiCN coating extends tool life in ferrous and abrasive materials
• 0.015 inch corner radius reduces stress risers at the cutting edge
• Centercutting geometry allows direct plunge entry without a pre-drilled hole
• Right-hand cut and right-hand spiral flute direction for standard CNC spindle compatibility
• Extra-long 4 inch overall length for deep-pocket and hard-to-reach milling

Compatibility

Designed for use in CNC machining centers and manual mills accepting a 1/4 inch shank. Suitable as an OEM-style replacement or standard tooling selection for 1/4 inch collet or end mill holder setups requiring a corner radius profile.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholder torque and runout specifications. Ensure the spindle is fully stopped and the machine is in a safe state before loading or changing tooling. Inspect collet and toolholder for wear or contamination before seating the shank. Verify runout at setup, as the tight shank diameter tolerance (-0.0001 to -0.0004 inch) requires a clean, undamaged holder bore for proper fit.
