Accupro 14556361 Corner Radius End Mill 3/16 in 4 Flute Carbide

Product Description

The ACCUPRO 14556361 is a solid carbide corner radius end mill engineered for precision milling operations in demanding shop environments. Built from micrograin carbide and coated with AlTiN+ for heat and wear resistance, this tool handles hardened steels, stainless alloys, and abrasive workpiece materials. It features a 3/16 inch mill diameter, a 3/8 inch length of cut, and a 0.015 inch corner radius that extends tool life and reduces chipping at the cutting edge. The 4-flute, right-hand spiral geometry promotes efficient chip evacuation. Machinists and CNC operators install this end mill in vertical machining centers, CNC mills, and manual knee mills requiring fine-radius corner geometry.

This end mill suits precision contouring, slotting, and profiling applications where corner breakdown is a concern. The stub length configuration and straight cylindrical shank make it a practical choice for high-rigidity setups in tight clearance situations. It is centercutting, allowing direct plunge entry, and its right-hand cutting direction is compatible with standard spindle configurations. Typical applications include die and mold work, aerospace component machining, and close-tolerance part production in job shop and production environments.

Key Features

• AlTiN+ coating provides elevated heat resistance and extended tool life on ferrous and hardened materials
• Micrograin solid carbide substrate delivers superior rigidity and edge retention compared to high-speed steel
• 0.015 inch corner radius reduces edge chipping and improves surface finish at workpiece corners
• Centercutting design allows plunge milling without a pre-drilled entry point
• 4-flute right-hand spiral geometry balances chip evacuation and surface finish quality
• Stub length construction maximizes rigidity and minimizes deflection in close-tolerance cuts

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC and manual milling machines accepting a 3/16 inch straight cylindrical shank end mill in Series 6/44 configuration.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing tooling. Seat the shank fully in a collet or end mill holder and torque the retention mechanism to the machine manufacturer specification. Verify runout with a dial indicator before beginning a production cut to confirm proper seating and avoid premature tool failure.
