Accupro 12176874 Corner Radius End Mill 0.0313in 4 Flute

Product Description

The ACCUPRO 12176874 is a solid carbide corner radius end mill designed for precision milling operations requiring a controlled edge radius and tight dimensional tolerances. With a 0.0313-inch cutting diameter and a 0.005-inch corner radius, this tool reduces stress concentrations at the cutting edge and improves surface finish in slotting, profiling, and pocket-milling applications. The 4-flute, right-hand spiral geometry delivers efficient chip evacuation and stable cutting action. Micrograin carbide construction provides the hardness and wear resistance needed for demanding cuts in ferrous and non-ferrous materials. This end mill is intended for use by machinists and tooling professionals working on CNC machining centers and manual mills.

This end mill is suited for fine detail work in mold making, die work, and precision part machining where sharp inside corners must be avoided or radius blending is required. The single-end, centercutting design allows plunge entry in addition to standard peripheral and slot cutting. The bright, uncoated finish makes it a practical choice for aluminum, brass, and other non-ferrous materials where coating adhesion is not required and tool identification after use is straightforward.

Key Features

• 0.0313-inch cutting diameter with a 0.005-inch corner radius for controlled edge blending
• 4-flute right-hand spiral geometry for efficient chip removal and surface finish
• Solid micrograin carbide construction for hardness and wear resistance
• Centercutting design allows plunge milling in addition to peripheral cuts
• Bright/uncoated finish suitable for non-ferrous and general-purpose milling
• Single-end configuration with 0.375-inch length of cut and 1.5-inch overall length

Compatibility

Designed as an OEM-style replacement or direct tooling selection for CNC machining centers and manual milling machines accepting a 0.125-inch straight shank.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully de-energized and at a complete stop before changing tooling. The 0.125-inch shank should be secured in a compatible collet or end mill holder to the manufacturer-specified clamping depth. Verify runout with a dial indicator after installation and before beginning any cut to protect both the tool and the workpiece.
