Accupro 12182885 Corner Radius End Mill 3/8 in 4 Flute

Product Description

The ACCUPRO 12182885 is a single-end corner radius end mill designed for precision milling in ferrous and non-ferrous materials. Built from micrograin solid carbide, it delivers the rigidity and wear resistance required for demanding cutting operations. The tool features a 0.03 inch corner radius that reduces stress concentrations at the cutting edge, extending tool life in high-cycle production environments. A TiCN coating lowers friction and improves hardness at the cutting surface. With a 40-degree helix angle and 4 right-hand spiral flutes, the 12182885 promotes efficient chip evacuation and stable cutting performance. Licensed machinists and CNC tooling specialists are the primary installers and operators of this tool.

This end mill is suited for stub-length milling applications in vertical and horizontal machining centers, as well as manual milling machines. The 3/8 inch mill diameter and 5/8 inch length of cut make it appropriate for slotting, profiling, and contouring passes where a corner radius is specified to reduce part stress or match a drawing callout. The centercutting design allows plunge entry. Right-hand cutting direction is standard for conventional spindle rotation. This tool is appropriate for shops working in tool steel, stainless, aluminum, and similar materials where TiCN coating provides an advantage.

Key Features

• Micrograin solid carbide construction for rigidity and extended tool life
• TiCN coating reduces friction and improves surface hardness at the cutting edge
• 0.03 inch corner radius reduces stress at part corners and protects the cutting edge
• 40-degree helix angle with 4 right-hand spiral flutes promotes efficient chip evacuation
• Centercutting design permits direct plunge entry without a pilot hole
• Stub-length geometry provides added rigidity in short-reach applications

Compatibility

Designed as an OEM-style replacement or standard tooling selection for 3/8 inch collet or end mill holder setups on CNC machining centers and manual milling machines requiring a corner radius end mill with a 3/8 inch shank.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. The machine spindle must be fully stopped and the tool changer or spindle lock engaged before mounting or removing the end mill. Verify collet size matches the 3/8 inch shank diameter before tightening. Inspect the tool for edge chipping or coating wear before each use, and confirm runout is within acceptable limits after seating in the holder.
