Accupro 12183230 Corner Radius End Mill 1/4 in 4 Flute

Product Description

The ACCUPRO 12183230 is a solid carbide corner radius end mill designed for precision milling operations requiring a controlled edge radius and extended reach. With a 1/4 inch diameter, a 1-1/2 inch length of cut, and a 0.045 inch corner radius, this tool produces smooth, radiused transitions at the base of milled features while reducing stress concentrations. The 4-flute, right-hand spiral configuration supports efficient chip evacuation and surface finish quality. Micrograin carbide construction provides the hardness and wear resistance needed for demanding cutting applications. Machinists and tool-and-die professionals use this end mill in CNC machining centers and manual mills.

This end mill is suited for profiling, slotting, and contouring operations in ferrous and non-ferrous materials where a corner radius is required rather than a sharp 90-degree edge. The extra-long 4 inch overall length and 1/4 inch shank diameter make it appropriate for deep-pocket work or applications requiring extended reach. The bright/uncoated finish makes it a general-purpose choice across a range of workpiece materials. Single-end, centercutting geometry allows for both plunge and lateral entry cuts.

Key Features

• 0.045 inch corner radius reduces edge chipping and stress at milled corners
• Micrograin solid carbide construction for hardness and extended tool life
• 4 flutes with right-hand spiral and right-hand cutting direction
• Centercutting design allows direct plunge entry into workpiece
• Extra-long 4 inch OAL provides reach for deep-pocket milling
• Bright/uncoated finish compatible with a wide range of materials

Compatibility

Designed as an OEM-style replacement or standard tooling selection for CNC machining centers and manual mills accepting a 1/4 inch straight shank end mill.

Installation Notes

Installation should be performed by a qualified machinist familiar with tool holder specifications and runout tolerances. Ensure the machine spindle and tool holder are clean and free of debris before seating the shank. Verify shank engagement depth meets tool holder manufacturer minimums before operation. Always confirm spindle speed and feed rate settings are appropriate for the workpiece material before beginning a cut.
