Accupro 14556363 Corner Radius End Mill 3/16 in 4 Flute

Product Description

The ACCUPRO 14556363 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and hard materials. It features a 3/16 inch diameter with a 0.03 inch corner radius, 4 flutes, and an AlTiN+ coating that improves heat resistance and tool life at elevated cutting temperatures. The overall length is 2 inches with a 3/8 inch length of cut and a 3/16 inch straight-cylindrical shank. Right-hand cutting and right-hand flute direction are standard. This tool is used by machinists and toolroom operators running CNC mills or manual knee mills where edge blending and corner protection are required.

The 14556363 is suited for stub-length applications where rigidity matters more than reach. The centercutting geometry allows plunge entry, giving operators flexibility in tool paths without a separate drilling operation. The AlTiN+ coating performs well in dry or minimum-quantity lubrication setups on alloy steels, stainless steels, and hardened materials. The micrograin carbide substrate supports tight tolerances and resists chipping under interrupted cuts. This is a single-end tool from ACCUPRO Series 6/44, sold individually.

Key Features

• AlTiN+ coating for extended tool life in high-temperature cutting applications
• Micrograin solid carbide substrate for edge stability and wear resistance
• Centercutting design allows direct plunge entry into workpiece
• 0.03 inch corner radius reduces stress concentration at milled corners
• Right-hand spiral flutes with 40-degree helix angle for efficient chip evacuation
• Stub length construction maximizes rigidity and minimizes deflection

Compatibility

Designed as a standard straight-shank end mill compatible with ER collet chucks, end mill holders, and other 3/16 inch bore toolholding systems used on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the control is in an E-stop or tool-change state before mounting or removing the tool. Seat the shank fully in the holder and torque the collet nut or set screws per the toolholder manufacturer specifications. Inspect the cutting edges for chips or coating damage before each use.
