Harvey Tool 36210-C4 Corner Radius End Mill 1/4 in Carbide

Product Description

The HARVEY TOOL 36210-C4 is a solid carbide corner radius end mill designed for precision milling in demanding material applications. With a 1/4 inch mill diameter, 3/4 inch length of cut, and a 0.01 inch corner radius, this tool is built for tight-tolerance work where edge integrity and surface finish matter. The amorphous diamond (PVD) coating extends tool life and reduces friction across a wide range of workpiece materials. It runs four flutes in a right-hand spiral configuration with a 30-degree helix angle, making it suitable for both roughing and finishing operations on a single-end setup. Machinists and toolroom professionals working on CNC machining centers will find this a reliable miniature end mill for detail work.

This end mill is rated for use on steel, stainless steel, cast iron, non-ferrous metals, aluminum, wood, and composite materials. It fits into the HARVEY TOOL Miniature End Mills - Corner Radius - Stub and Standard series, making it a go-to option for small-scale features, slots, and profiling cuts where a sharp corner radius transition is required. Its straight-cylindrical 1/4 inch shank diameter fits standard toolholders without additional adapters. It is center-cutting and supports both plunge and ramp entry strategies.

Key Features

• 0.01 inch corner radius with a tight tolerance of plus or minus 0.001 inch for consistent edge geometry
• Amorphous diamond PVD coating for improved wear resistance and reduced built-up edge
• Four-flute right-hand spiral design supports both roughing and finishing in a single tool
• Center-cutting geometry allows direct plunge entry into workpieces
• 30-degree helix angle promotes efficient chip evacuation in deep-slot and profiling applications
• Solid carbide construction provides rigidity and heat resistance at elevated cutting speeds

Compatibility

Compatible with standard toolholders accepting a 1/4 inch straight-cylindrical shank. Designed for use on CNC machining centers and manual mills across steel, stainless steel, cast iron, aluminum, non-ferrous metals, wood, and composite workpiece materials as specified by HARVEY TOOL for this series.

Installation Notes

This end mill is installed and serviced by machinists and toolroom technicians operating CNC or manual milling equipment. Ensure the spindle is fully stopped and the machine is in a safe lockout state before changing tooling. Seat the shank fully in the toolholder and torque the retention hardware according to the toolholder manufacturer specifications. Inspect the corner radius and cutting edges before each use; solid carbide tooling is brittle and should not be dropped or used if chipping is visible.
