Accupro 12182424 Corner Radius End Mill 3/16 in 4 Flute

Product Description

The ACCUPRO 12182424 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and non-ferrous materials. With a 3/16 inch (0.1875 inch) mill diameter and a 0.045 inch corner radius, this tool produces controlled edge breaks and blended contours in a single pass. The TiCN coating improves surface hardness and wear resistance, extending tool life in demanding cutting conditions. Four right-hand spiral flutes with a 40-degree helix angle promote efficient chip evacuation and smooth cutting action. This end mill is used by machinists and tool-and-die professionals working in production shops, mold making, and general CNC machining environments.

This tool is suited for slot milling, profile milling, and corner-radius contouring on CNC machining centers and manual mills. The centercutting geometry allows plunge entry, adding flexibility for pocketing operations. The 3/16 inch shank diameter matches the mill diameter for direct collet or end mill holder mounting. With a 5/8 inch length of cut and a 2 inch overall length, it is well-suited for shallow-to-medium depth cuts in tight workpiece geometries where reach must be controlled.

Key Features

• 0.045 inch corner radius produces consistent, repeatable edge blends and reduces stress concentrations at workpiece corners
• TiCN coating provides increased hardness and wear resistance compared to uncoated carbide
• Micrograin solid carbide substrate delivers rigidity and resistance to chipping under high feed rates
• Centercutting design enables direct plunge entry without a pre-drilled pilot hole
• 40-degree right-hand helix promotes chip flow and reduces heat buildup at the cutting edge
• Single-end configuration with 4 flutes balances cutting efficiency and chip clearance

Compatibility

Designed as an OEM-style solid carbide end mill for use in standard 3/16 inch collets, end mill holders, or shrink-fit tooling on CNC machining centers and manual vertical mills.

Installation Notes

Installation should be performed by a qualified machinist following established shop safety procedures. Ensure the spindle is fully stopped and the machine is locked out before mounting or removing the tool. Seat the shank fully in a clean, properly sized collet or end mill holder and torque the retention hardware to the holder manufacturer's specification. Confirm runout is within acceptable limits before beginning a production cut.
