Accupro 12176877 Corner Radius End Mill 0.0313in 4 Flute

Product Description

The ACCUPRO 12176877 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining environments. Measuring 0.0313 inches in diameter with a 0.005-inch corner radius, this single-end, centercutting tool removes material cleanly at tight tolerances. The 4-flute, right-hand spiral configuration paired with a TiCN coating supports extended tool life in ferrous and non-ferrous applications. Micrograin carbide construction provides the rigidity and edge retention required for fine-detail cuts at small diameters. Machinists and CNC operators working with close-tolerance components will find this tool suited to demanding finish and profiling work.

This end mill is used in CNC machining centers and manual mills where small-diameter, close-tolerance milling is required. Its 3/32-inch length of cut and 1/8-inch shank diameter make it appropriate for shallow slotting, profiling, and contouring operations in confined areas. The centercutting geometry allows plunge entry. It is a single-end tool sold individually, suited for job shops, tool rooms, and production environments handling small, detailed workpieces in steel, stainless, aluminum, and similar materials.

Key Features

• 0.0313-inch mill diameter with micrograin solid carbide construction for rigidity at small scale
• 0.005-inch corner radius reduces stress concentration and improves edge durability
• TiCN coating extends tool life and reduces friction in ferrous and non-ferrous cuts
• 4-flute, right-hand spiral design supports efficient chip evacuation and surface finish
• Centercutting geometry allows direct plunge entry without pilot drilling
• 1/8-inch shank diameter compatible with standard collet and chuck systems

Compatibility

Designed for use in CNC machining centers and conventional mills accepting a 1/8-inch shank diameter. Verify spindle collet or chuck sizing before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank fully within the collet or chuck to the recommended engagement depth per machine manufacturer guidelines. Confirm runout with a dial indicator before beginning production cuts, particularly at this diameter where small runout values have a proportionally large effect on tool life and part accuracy.
