Accupro 14797588 Corner Radius End Mill 1/4 in 4 Flute

Product Description

The ACCUPRO 14797588 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining environments. With a 1/4 inch diameter and a 0.0200 inch corner radius, it produces clean, radiused inside corners that reduce stress concentrations in finished workpieces. The four-flute configuration provides a balance of chip clearance and surface finish quality. At 2-1/2 inches overall length with a 3/4 inch length of cut, this tool fits standard toolholders used on CNC machining centers and manual mills. It is centercutting, allowing plunge entry into the workpiece. Machinists and CNC operators in job shops, production facilities, and tool rooms are the primary users.

This end mill is suited for finishing and light profiling passes in ferrous and non-ferrous materials where a radiused corner profile is required. The miniature series designation reflects its small-diameter geometry, making it appropriate for detailed pocket milling, slot work, and contouring operations where tight tolerances are critical. The bright, uncoated finish makes it a cost-effective choice for general-purpose applications or for use with cutting fluids in controlled machining environments.

Key Features

• Solid carbide micrograin construction for rigidity and wear resistance in small-diameter tooling
• 0.0200 inch corner radius for consistent radiused edges and reduced stress risers in milled features
• Four flutes with right-hand spiral cut and right-hand cutting direction for standard CNC and manual mill setups
• Centercutting geometry allows direct plunge entry without pre-drilling
• Single-end tool with 1/4 inch shank diameter for compatibility with standard collet systems
• 30 degree helix angle supports smooth chip evacuation during profiling and slotting passes

Compatibility

Designed as an OEM-style replacement and standard-fitment cutting tool for 1/4 inch collet systems on CNC machining centers, vertical mills, and routers requiring a corner radius end mill in the miniature series range.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool is secure in a clean, properly sized collet or toolholder before beginning setup. Confirm runout is within acceptable limits before engaging the cut. Follow applicable shop safety protocols and machine manufacturer guidelines for toolholder torque and speed-feed parameters appropriate to the workpiece material.
