Accupro 12176825 Corner Radius End Mill 1 in 2 Flute Carbide

Product Description

The ACCUPRO 12176825 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining applications. It features a 1 inch cutting diameter, a 1.75 inch length of cut, and a 0.045 inch corner radius that reduces stress concentrations at the base of a cut and extends tool life on contoured profiles. With 2 flutes and a right-hand spiral flute design, it delivers efficient chip evacuation and a clean finish. The micrograin carbide substrate provides the hardness and wear resistance needed for demanding cuts in ferrous and non-ferrous materials. This end mill is installed by machinists and CNC programmers in production and job shop environments.

This end mill is suited for slotting, profiling, and ramping operations where a corner radius is specified by the part print. The single-end, centercutting design allows plunge entry and flexible toolpath strategies. With a 1 inch shank diameter and 4 inch overall length, it seats securely in standard end mill holders, collet chucks, and shrink-fit tooling systems. It is appropriate for use in vertical machining centers, horizontal machining centers, and manual knee mills. Applications include mold and die work, aerospace component machining, and general precision part production.

Key Features

• 0.045 inch corner radius reduces stress risers and improves surface finish at part transitions
• Solid micrograin carbide construction for hardness and wear resistance
• 2-flute right-hand spiral geometry promotes efficient chip removal
• Centercutting design allows direct plunge entry without a pre-drilled hole
• Bright/uncoated finish suitable for use with cutting fluids across a range of workpiece materials
• 40-degree helix angle supports aggressive feed rates and smooth cutting action

Compatibility

Designed as an OEM-style solid carbide corner radius end mill compatible with standard 1 inch end mill holders, collet chucks, and shrink-fit tooling systems used in CNC and manual milling equipment.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Verify holder runout is within acceptable limits before committing to production cuts, as excessive runout will accelerate wear and compromise corner radius tolerance. Follow applicable shop safety procedures and machine guarding requirements during setup and operation.
