Accupro 12176627 Corner Radius End Mill 5/8 in 3 Flute

Product Description

The ACCUPRO 12176627 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining applications. It features a 5/8 inch diameter with a 0.025 inch corner radius that reduces stress concentration at the cutting edge, extending tool life and improving surface finish on workpiece corners and slots. With 3 right-hand spiral flutes and a bright uncoated finish, this single-end, centercutting tool handles a 7/8 inch length of cut at a 40-degree helix angle. The micrograin carbide construction provides hardness and wear resistance suited to demanding cutting conditions. Licensed machinists and CNC operators are the primary users of this tooling.

This end mill is suited for use in vertical and horizontal machining centers, CNC mills, and manual knee mills where a corner radius profile is required. It is appropriate for slotting, profiling, and peripheral milling in ferrous and non-ferrous materials. The centercutting geometry allows plunge entry into the workpiece, adding versatility in multi-axis and 3D contouring operations. The 5/8 inch shank diameter fits standard ER and straight-bore tool holders commonly found in production and job-shop environments.

Key Features

• 0.025 inch corner radius reduces edge chipping and improves corner surface finish
• Solid micrograin carbide construction for high hardness and extended tool life
• 3 right-hand spiral flutes with 40-degree helix angle for efficient chip evacuation
• Centercutting design allows direct plunge entry without pre-drilling
• Bright uncoated finish suitable for a wide range of materials including aluminum and non-ferrous alloys
• Single-end configuration with 3 inch overall length for reach in standard setups

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide corner radius end mill for standard 5/8 inch straight-bore and collet-style tool holders used in CNC and manual milling machines.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. The machine spindle must be fully stopped and locked out before changing tooling. Confirm that the tool holder bore and collet size match the 5/8 inch shank diameter before seating the end mill. Proper tool runout should be verified with a dial indicator after tightening to ensure accurate cuts and prevent premature tool wear.
